The Catalyst , , and switches do not support switch stacking. Unless otherwise noted, the term switch refers to a standalone switch and to a switch stack. Verify that these release notes are correct for your switch:. You can download the switch software from this site registered Cisco. This software release is part of a special release of Cisco IOS software that is not released on the same 8-week maintenance cycle that is used for other platforms.

As maintenance releases and future software releases become available, they will be posted to Cisco. The system requirements are described in these sections:. Table 1 lists the hardware supported on this release. Each uplink port is considered a single interface with dual front ends RJ connector and SFP module slot.

The dual front ends are not redundant interfaces, and only one port of the pair is active. Cisco EtherSwitch service module.

These sections describes the hardware and software requirements for using the device manager:. Table 2 lists the minimum hardware requirements for running the device manager.

Table 2 Minimum Hardware Requirements. Table 3 lists the supported operating systems and browsers for using the device manager. The device manager verifies the browser version when starting a session to ensure that the browser is supported. Note The device manager does not require a plug-in.

Table 3 Supported Operating Systems and Browsers. Service Pack 1 or higher is required for Internet Explorer 5. You cannot create and manage switch clusters through the device manager. To create and manage switch clusters, use the command-line interface CLI or the Network Assistant application. When creating a switch cluster or adding a switch to a cluster, follow these guidelines:.

Cisco IOS These are the procedures for downloading software. Before downloading software, read this section for important information:. A subdirectory contains the files needed for web management. The image is stored on the system board flash device flash:. You can use the show version privileged EXEC command to see the software version that is running on your switch.

The second line of the display shows the version. Note For Catalyst and switches and the Cisco EtherSwitch service modules, although the show version output always shows the software image running on the switch, the model name shown at the end of this display is the factory configuration IP base image [formerly known as the SMI] or IP services image [formerly known as the EMI] and does not change if you upgrade the software image. You can also use the dir filesystem : privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.

The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file. This file contains the Cisco IOS image file and the files needed for the embedded device manager.

You must use the combined tar file to upgrade the switch through the device manager. The image that provides full Layer 3 routing and advanced services was referred to as the enhanced multilayer image EMI. Table 5 lists the filenames for this software release.

Catalyst IP base image and device manager files. This image also runs on the Cisco EtherSwitch service modules. Catalyst IP services image and device manager files. Catalyst IP base cryptographic image and device manager files.

Catalyst IP services cryptographic image and device manager files. Catalyst advanced IP services image, cryptographic file, and device manager files. Catalyst IP base image file and device manager files. Catalyst image file and device manager files. Catalyst cryptographic image file and device manager files. This image has the Kerberos and SSH features. Catalyst LAN lite cryptographic image file and device manager files.

Catalyst LAN lite image file and device manager files. The switch and the internal controller run separate software versions, which must be upgraded separately. If the image versions are not compatible, the wireless LAN controller switch could stop functioning. Table 6 is the compatibility matrix for Catalyst and wireless controller. Before upgrading your switch software, make sure that you have archived copies of the current Cisco IOS release and the Cisco IOS release to which you are upgrading.

You should keep these archived images until you have upgraded all devices in the network to the new Cisco IOS image and until you have verified that the new Cisco IOS image works properly in your network. See Product Bulletin for more information:. You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a host by using the copy flash: tftp: privileged EXEC command.

We recommend that you download the tar file from Cisco. You can also configure the switch as a TFTP server to copy files from one switch to another without using an external TFTP server by using the tftp-server global configuration command.

You can upgrade switch software by using the device manager or Network Assistant. For detailed instructions, click Help. Note When using the device manager to upgrade your switch, do not use or close your browser session after the upgrade process begins. Wait until after the upgrade process completes. This procedure is for copying the combined tar file to the switch.

You copy the file to the switch from a TFTP server and extract the files. You can download an image file and replace or keep the current image. Step 1 Use Table 5 to identify the file that you want to download.

Step 2 Download the software image file. If you have a SmartNet support contract, go to this URL, and log in to download the appropriate files:. To download the image for a Catalyst switch, click Catalyst software.

To obtain authorization and to download the cryptographic software files, click Catalyst 3DES Cryptographic Software. For more information, see Appendix B in the software configuration guide for this release.

Step 4 Log into the switch through the console port or a Telnet session. For more information about assigning an IP address and default gateway to the switch, see the software configuration guide for this release. If you are installing the same version of software that is currently on the switch, overwrite the current image by entering this privileged EXEC command:. Directory and image names are case sensitive.

This example shows how to download an image from a TFTP server at You can assign IP information to your switch by using these methods:. These sections describe the new supported hardware and the new and updated software features provided in this release:.

This release supports these new Catalyst switches:. These sections describe the new software features for this release:. This is the new feature for the Catalyst , , , and switches:. IEEE These are the new features for the Catalyst , , , and switches:. These are the new features for the Catalyst and switches:.

Table 7 lists the minimum software release required to support the major features of the Catalyst , , , and switches and the Cisco EtherSwitch service modules. Multicast virtual routing and forwarding VRF lite.

Support for auto rendezvous point auto-RP for multicast. Generic online diagnostics to test the hardware functionality of the supervisor engine. Stack MAC persistent timer and archive download enhancements. Support for configuring an IEEE Layer 2 point-to-point tunneling and Layer 2 point-to-point tunneling bypass. Support for SSL version 3.

Cisco intelligent power management to limit the power allowed on a port, or pre-allocate reserve power for a port. Software upgrade device manager or Network Assistant only.

You should review this section before you begin working with the switch. These are known limitations that will not be fixed, and there is not always a workaround.

Some features might not work as documented, and some features could be affected by recent changes to the switch hardware or software. Unless otherwise noted, these limitations apply to the Catalyst , , , and switches and the Cisco EtherSwitch service modules:.

These are the configuration limitations:. This problem occurs under these conditions:. The workaround is to reconfigure the static IP address. Change the routed port to a nonrouted port or the reverse. Re-enable auto-QoS on the interface.

If the file is manually removed from the file system, the DHCP snooping database does not create another database file. You need to disable the DHCP snooping database and enable it again to create the database file. No workaround is necessary; these are the designed behaviors. When you enter the show ip arp inspection log privileged EXEC command, the log entries from all switches in the stack are moved to the switch on which you entered the command.

The workaround is to enter the no switchport block unicast interface configuration command on that specific interface. There is no workaround. This is a cosmetic error and does not affect the functionality of the switch. To change the baud rate, reload the Cisco EtherSwitch service module with the bootloader prompt.

You can then change the baud rate and change the speed on the TTY line of the router connected to the Cisco EtherSwitch Service module console. The workaround is to use switch ports other than those specified for redundancy and for applications that immediately detect active links. High CPU utilization can also occur with other conditions, such as when debug messages are logged at a high rate to the console.

The workaround is to configure aggressive UDLD. If the Cisco EtherSwitch service module is in access mode, the workaround is to enter the spanning-tree portfast interface configuration command on the internal Gigabit Ethernet interface. If the service module is in trunk mode, there is no workaround. If this happens, uneven traffic distribution will happen on EtherChannel ports. Changing the load balance distribution method or changing the number of ports in the EtherChannel can resolve this problem.

Use any of these workarounds to improve EtherChannel load balancing:. For example, with load balance configured as dst-ip with distinct incrementing destination IP addresses, and the number of ports in the EtherChannel set to either 2, 4, or 8, load distribution is optimal. When the active switch fails in a switch cluster that uses HSRP redundancy, the new active switch might not contain a full cluster member list.

The workaround is to ensure that the ports on the standby cluster members are not in the spanning-tree blocking state. The workaround for networks with pre-standard powered devices is to leave the maximum wattage set at the default value You can also configure the maximum wattage for the port for no less than the value the powered device reports as the power consumption through CDP messages.

For networks with IEEE Class 0, 3, or 4 devices, do not configure the maximum wattage for the port at less than the default The workaround is to enter the power inline never interface configuration command on all the Fast Ethernet ports that are not powered by but are connected to IP phones if the problem persists. The workaround is to enable PoE and to configure the switch to recover from the PoE error-disabled state. CiscoWorks is not supported on the Catalyst FS switch. The switchport block multicast interface configuration command is only applicable to non-IP multicast traffic.

The workaround is to enter the clear ip mroute privileged EXEC command on the interface. After you configure a switch to join a multicast group by entering the ip igmp join-group group-address interface configuration command, the switch does not receive join packets from the client, and the switch port connected to the client is removed from the IGMP snooping forwarding table.

The workaround is to enable IP routing or to disable multicast routing on the switch. You can also use the ip igmp snooping querier global configuration command if IP multicast routing is enabled for queries on a multicast router port.

These are the powers limitation for the Cisco EtherSwitch service modules:. You should use the power inline never interface configuration command on Cisco EtherSwitch service module ports that are not connected to PoE devices. This is not a problem because the display correctly shows the total used power and the remaining power available on the system.

The workaround is to enter the shutdown and the no shutdown interface configuration commands on the Fast Ethernet interface of a new IP phone that is attached to the service module port after the internal link is brought up. These are the quality of service QoS limitations:. This error message means there is a temporary memory shortage that normally recovers by itself. You can verify that the switch stack has recovered by entering the show cef line user EXEC command and verifying that the line card states are up and sync.

No workaround is required because the problem is self-correcting. The workaround is to change any one of the listed conditions. The workaround is to use an IP address as the next hop instead of an interface.

CSCsi [Catalyst and switches]. This is a hardware limitation and only applies to these switches CSCdy :. This is a hardware limitation and only applies to these switches CSCea :. These are the Catalyst and Cisco EtherSwitch service module switch stack limitations:. This occurs after a stack master re-election when the previous stack master was running the IP services image formerly known as the EMI and the new stack master is running the IP base image formerly known as the SMI.

These are the workarounds. Only one of these is necessary:. This is the expected behavior of the offline configuration provisioning feature. The workaround is to copy the bootable image to the parent directory or first directory. The workaround is to assign a lower path cost to the forwarding port. This can but does not always occur during link flaps and does not last for more than a few milliseconds.

No manual intervention is needed. The problem corrects itself within a short interval after the link flap as all the switches in the stack synchronize with the new load-balance configuration. The workaround is to reboot the new member switch. Use the remote command all show run privileged EXEC command to compare the running configurations of the stack members.

The workaround is to reduce the number of VLANs or trunks. The workaround is to define another policy-map name for the second-level policy-map with the same configuration to be used for another policy-map.

The workaround is to configure the burst interval to more than 1 second. CSCse, Catalyst switches only. The workaround is to enter the switchport access vlan dynamic interface configuration command separately on each port.

The workaround is to click Yes when you are prompted to accept the certificate. These sections describe the important notes related to this software release for the Catalyst , , , and switches and for the Cisco EtherSwitch service modules:. If this message appears, check that there is network connectivity between the switch and the ACS.

If this happens, enter the no auto qos voip cisco-phone interface command on all interface with this configuration to delete it. Then enter the auto qos voip cisco-phone command on each of these interfaces to reapply the configuration.

From the Settings window, choose Automatically. Click OK to exit the Internet Options window. Configure the HTTP server interface for the type of authentication that you want to use. You should write down the port number through which you are connected.

Use care when changing the switch IP information. If you are not using the default method of authentication the enable password , you need to configure the HTTP server interface with the method of authentication used on the switch. This section describes the open caveats with possible unexpected activity in this software release. Unless otherwise noted, these severity 3 Cisco IOS configuration caveats apply to the Catalyst , , , and switches and to Cisco EtherSwitch service modules:.

When connected to the router through an auxiliary port in a session to a Cisco EtherSwitch service module, the service module session fails when you enter the shutdown and the no shutdown interface configuration commands on the service module router interface. When the router is rebooted after it is powered on approximately once in 10 to 15 reboots , the Router Blade Communication Protocol RBCP between the router and the EtherSwitch service module might not be reestablished, and this message appears:.

The workaround is to reload the EtherSwitch service module software without rebooting the router. The switch might display tracebacks similar to these examples when a large number of IEEE Jan 3 L3A3 Jan 3 Jan 3 When IEEE The workaround is to enable the dot1x system-auth-control global configuration command before attempting to configure interface level IEEE The workaround is to enable IP routing on the switch by entering the ip routing global configuration.

When you enable routing, the VRF is cleared from the deleted queue. When you enter the boot host retry timeout global configuration command to specify the amount of time that the client should keep trying to download the configuration and you do not enter a timeout value, the default value is zero, which should mean that the client keeps trying indefinitely.

However, the client does not keep trying to download the configuration. The workaround is to always enter a non zero value for the timeout value when you enter the boot host retry timeout timeout-value command.

A stack member switch might fail to bundle Layer 2 protocol tunnel ports into a port channel when you have followed these steps:. You configure a Layer 2 protocol tunnel port on the master switch. You configure a Layer 2 protocol tunnel port on the member switch. You add the port channel to the Layer 2 protocol tunnel port on the master switch.

You add the port channel to the Layer 2 protocol tunnel port on the member switch. After this sequence of steps, the member port might stay suspended.

The workaround is to configure the port on the member switch as a Layer 2 protocol tunnel and at the same time also as a port channel. For example:. When a RIP network and IP address are configured on an interface, a traceback error occurs after you enter the shutdown, no shutdown, switchport and no switchport interface configuration commands.

In a mixed stack of Catalyst switches and Catalyst E switches, when the stack reloads, the Catalyst E might not become stack master, even it has a higher switch priority set.

The workaround is to check the flash. If it contains many files, remove the unnecessary ones. Check the lost and found directory in flash and if there are many files, delete them. To check the number of files use the fsck flash: command. You only need to do one of these.

The workaround is to specify the egress interface on the IPv6 static route. The workaround is to delete the child policy, which removes it from the parent policy.

Then recreate the child policy with the same or a different name and reference it in the parent policy. The parent policy then successfully attaches to the SVI. This adversely affects network management applications such as CiscoWorks CiscoView because they cannot manage the switch.

System capabilities appear correctly, but the enabled capabilities are not identified if the switch is configured only as a Layer 2 switch. When a switch stack boots up, one or more traceback messages may appear on the switch console when the switch stack has these conditions:.

This should be executed after the VLAN database is in sync across the stack. When the configuration file is removed from the switch and the switch is rebooted, port status for VLAN 1 and the management port Fast Ethernet 0 is sometimes reported as up and sometimes as down , resulting in conflicts.

This status depends on when you respond to the reboot query:. Would you like to enter the initial configuration dialog? This is the correct state.

The workaround is to wait for approximately 1 minute after rebooting and until the VLAN 1 interface line status appears on the console before you respond to the query. After a stack bootup, the spanning tree state of a port that has IEEE This can occur on a voice port where the Port Fast feature is enabled. The workaround is to enter a shutdown interface configuration command followed by a no shutdown command on the port in the blocked state.

When the switch uses HTTP web-based authentication, a memory leak no longer occurs after authorization and policy download. A switch no longer displays processor memory-allocation failure messages under these conditions:. Note If the hardware configuration is not a switch stack, AAA requests might fail and the switch might experience high CPU usage for the authentication manager process. In addition, if the hardware configuration is a switch stack and This is resolved in Cisco IOS A switch no longer fails when a BGP peer flap occurs at the same time as a peer configuration policy is being modified.

RIP routes now correctly update when the maximum-paths 16 option is used. If any of the affected features are enabled, a successful attack will result in a blocked input queue on the inbound interface. Only crafted UDP packets destined for the device could result in the interface being blocked, transit traffic will not block the interface.

Cisco has released free software updates that address this vulnerability. Workarounds that mitigate this vulnerability are available in the workarounds section of the advisory.

A vulnerability in the handling of IP sockets can cause devices to be vulnerable to a denial of service attack when any of several features of Cisco IOS software are enabled. An EAP-Success message is now sent to a supplicant after it is authenticated on a port. When you apply the ip pim sparse mode and ip wccp web-cache redirect in configuration commands on a global table interface, traffic is now sent to multicast receivers.

Outgoing packets are no longer dropped from an interface with policy-based routing PBR :. A switch now boots correctly after a software reload or power cycle. In previous releases, under some rare circumstances, the image would be truncated to zero bytes and the switch would not boot. The dot1x timeout reauth-period server interface configuration command now works correctly.

In previous releases, the switch would reauthenticate correctly after the command was entered, but the switch would then reauthenticate every 10 minutes. Cisco IOS software contains a vulnerability in multiple features that could allow an attacker to cause a denial of service DoS condition on the affected device.

A sequence of specially crafted TCP packets can cause the vulnerable device to reload. Several mitigation strategies are outlined in the workarounds section of this advisory. IPv6 MLD snooping now continues to work correctly after a switch in the stack reloads. The switch now correctly processes ingress traffic when a port is configured with a short The username is now properly logged when the remote command privileged EXEC command is used to configure a cluster member.

A PoE switch no longer stops delivering power in certain conditions when a PoE device is reconnected after a port has gone down. This vulnerability could allow valid users to retrieve or write to any file on the device's file system, including the device's saved configuration and Cisco IOS image files, even if the CLI view attached to the user does not allow it.

This configuration file may include passwords or other sensitive information. The workaround is to not copy an SNMP configuration with a configuration file that contains crypto key generate rsa.

If the switch has existing keys, the Cisco IOS operating system expects either a Yes or No response that you want to replace the existing keys. If the switch does not have existing keys, the system expects the key size. When IEEE The workaround is to enable the dot1x system-auth-control global configuration command before attempting to configure interface level IEEE The workaround is to configure the burst interval to more than 1 second. The workaround is to remove the trust settings on a small number of ports one switch at a time.

If the problem still occurs, continue to reduce the number of ports. When cross-stack UplinkFast CSUF is configured on a switch and one of the member ports is flapping, packets transmitted from an EtherChannel port might be duplicated.

When there are more than five switches in a stack or when four or more switches join a stack, there might be a long delay between the time the Ready prompt appears and a switch that is starting up begins carrying traffic. This delay can last several minutes. However, this condition only causes a delay during switch startup, and no data is lost.

This causes intermittent unicast packet flooding in the network. The workaround is to enter the ping ip address privileged EXEC command from the switch to the next hop router to avoid the intermittent flooding. Clearing secure addresses by entering the clear port-security global configuration command in a stack member might cause traffic to be dropped from the switch. Some secure addresses learned on the stack master might not be learned on a stack member. Packets with a secure source address might also be dropped.

You only need to do one of these:. When both an authorized data domain and an authorized voice domain is present on a port, and you change the VLAN configuration on the port to equal the assigned VLAN, a traceback error appears.

This problem only occurs on the ports of a member switch. During repeated reauthentication of supplicants on an IEEE The workaround is to enable MAB by entering the dot1x mac-auth-bypass interface configuration command, or enter the dot1x timeout tx-period 1 to set the IEEE If IEEE The workaround is to enter the shutdown interface configuration command followed by the no shutdown command on the port connected to the client.

An IEEE The feature remains disabled until the link goes down on the port. The result is that if an IEEE Instead, the port keeps trying to authenticate the new host via IEEE The workaround is to enter the dot1x guest-vlan supplicant global configuration command to allow access to the guest VLAN even after EAPoL packets have been seen on a port.

This sections describes the caveats that have been resolved in this release:. Unless otherwise noted, these resolved caveats apply to the Catalyst , , , and switches and the Cisco EtherSwitch service modules. The output of the show ip route privileged EXEC command now correctly displays the default gateway. The stack master switch no longer resets with an error message when you enter the show storm-control user EXEC command and specify a stack member interface that is not configured for storm control.

The switch no longer reloads when the write core privileged EXEC command is entered when testing a core dump configuration and FTP is selected as the file transfer protocol. A switch no longer displays this error message when reading from or writing to the configuration file:. A vulnerability has been discovered in a third party cryptographic library which is used by a number of Cisco products. Due to the nature of the vulnerability it may be possible, in some cases, to trigger this vulnerability without a valid certificate or valid application-layer credentials such as a valid username or password.

Successful repeated exploitation of any of these vulnerabilities may lead to a sustained Denial-of-Service DoS ; however, vulnerabilities are not known to compromise either the confidentiality or integrity of the data or the device. These vulnerabilities are not believed to allow an attacker will not be able to decrypt any previously encrypted information. The vulnerable cryptographic library is used in the following Cisco products:.

Cisco has made free software available to address this vulnerability for affected customers. There are no workarounds available to mitigate the effects of the vulnerability. Note Another related advisory is posted together with this Advisory. It also describes vulnerabilities related to cryptography that affect Cisco IOS. When multiple hosts are authenticated on an IEEE Access control lists that are applied to routed ports on a member switch are now programmed into the switch hardware.

If two or more switches in a stack of PoE switches restarted at the same time and you entered the no switch stack-member-number provision global configuration command, this message no longer appears on the console:.

When an IEEE This is not a supported configuration. Only one host should be connected to an IEEE When a switch joins a stack running Cisco IOS If two Cisco EtherSwitch service modules were directly connected through Fast Ethernet interfaces configured as both Mbps and full duplex and as automatic speed and duplex settings, one interface might have detected the other as a Cisco-powered device.

In order to trigger these vulnerabilities, a malicious client must send malformed packets during the SSL protocol exchange with the vulnerable device. Cisco IOS is affected by the following vulnerabilities:. Cisco has made free software available to address these vulnerabilities for affected customers. There are workarounds available to mitigate the effects of these vulnerabilities. Note Another related advisory has been posted with this advisory.

This additional advisory also describes a vulnerability related to cryptography that affects Cisco IOS. A combined software table for Cisco IOS is available to aid customers in choosing a software releases that fixes all security vulnerabilities published as of May 22, When a stack of Catalyst switches are configured with a Layer 3 LACP EtherChannel, tracebacks are no longer generated when a stack master failover occurred.

When a Cisco device is configured for Network Admission Control and the EAP over UDP port number changes from its default value and then changes back with the eou default switch configuration command, the port change now takes effect.

When you configure a Cisco IP Phone to use Network Admission Control, the CDP packet is no longer delayed, and the phone is no longer identified as an agentless host without an identity profile. A nonstackable EtherSwitch Service Module no longer boots with this provisioned switch error message:. Secure server will use temporary self-signed certificate.

If a supplicant with that address is authenticated, its authorization is revoked. When you remove the bridge topology change trap with the no snmp-server enable traps bridge topologychange configuration command, the stpx root-inconsistency trap is now active. VRF is removed by using the no ip vrf global configuration command. When IGMP snooping is enabled and an EtherChannel member interface goes down, the switch now forwards multicast traffic on the rest of the EtherChannel member interfaces.

An authenticated Sometimes the switch dropped a fragmented multicast packet when it did not have the S,G entry, and more than packets per second pps of other multicast traffic were sent to the switch CPU. When you apply the mls qos trust dscp global configuration command to a port, this error message no longer appears:. When you remove and reconfigure a loopback interface, it no longer appears in the ifTable.

If the command is not configured on the master, it does not appear on the stack member switches. The output from the show interface global configuration command now shows private VLANs for notconnect ports. EtherChannels with very long allowed VLAN lists no longer experience a link flap when a master failover occurs.

A routing protocol flap no longer occurs when a stack member joins the stack. However, this does not affect switch functionality. If a Putty client is used to change the configuration to a device with SSH, the switch no longer stops responding to incoming traffic, such as SSH, Telnet, or ping packets. If fallback bridging is enabled on a routed port connected to an IEEE These vulnerabilities can be exploited when processing a malformed SNMPv3 message.

These vulnerabilities could allow the disclosure of network information or may enable an attacker to perform configuration changes to vulnerable devices. The SNMP server is an optional service that is disabled by default. Only SNMPv3 is impacted by these vulnerabilities. Workarounds are available for mitigating the impact of the vulnerabilities described in this document. This section provides these updates to the product documentation for the Catalyst , , , and switches:.

When you configure one end of an EtherChannel in either PAgP or LACP mode, the system negotiates with the other end of the channel to determine which ports should become active. In previous releases, the incompatible ports were suspended.

The port configuration does not change, but the port does not participate in the EtherChannel. For new messages in this release, see the Catalyst , , , , and Switch System Message Guide, You can use a web browser to authenticate a client that does not support IEEE You can configure a port to use only web authentication. You can also configure the port to first try and use IEEE Note The proxyacl entry determines the type of allowed network access.

For more information, see the Catalyst Software Configuration Guide. The console prompts you for a username and password on future attempts to access the switch console after entering the aaa authentication login command. If you do not want to be prompted for a username and password, configure a second login authentication list:. Configure the network access server to recognize and use vendor-specific attributes VSAs.

To disable the IP device tracking table, use the no ip device tracking global configuration commands. Beginning in privileged EXEC mode, follow these steps to configure a port to use web authentication:. Specify the port to be configured, and enter interface configuration mode.

Specify the default access control list to be applied to network traffic before web authentication. Optional Save your entries in the configuration file. This example shows how to configure only web authentication on a switch port:. Define a fallback profile to allow an IEEE Specify the default access control list to apply to network traffic before web authentication. Associate an IP admission rule with the profile, and specify that a client connecting by web authentication uses this rule.

Enable IEEE Configure the port to authenticate a client by using web authentication when no IEEE This example shows how to configure IEEE For more information about the ip admission name and dot1x fallback commands, see the command reference for this release.

Use the dot1xfallback interface configuration command on the switch stack or on a standalone switch to configure a port to use web authentication as a fallback method for clients that do not support IEEE To return to the default setting, use the no form of this command. Specify a fallback profile for clients that do not support IEEE You must enter the dot1x port-control auto interface configuration command on a switch port before entering this command.

This example shows how to specify a fallback profile to a switch port that has been configured for IEEE You can verify your settings by entering the show dot1x [ interface interface-id ] privileged EXEC command. Displays IEEE Use the fallback profile global configuration command on the switch stack or on a standalone switch to create a fallback profile for web authentication. Specify the fallback profile for clients that do not support IEEE The fallback profile is used to define the IEEE The only supported behavior is to fall back to web authentication.

After entering the fallback profile command, you enter profile configuration mode, and these configuration commands are available:. This example shows how to create a fallback profile to be used with web authentication:. You can verify your settings by entering the show running-configuration [ interface interface-id ] privileged EXEC command.

Configure a port to use web authentication as a fallback method for clients that do not support IEEE Use the ip admission interface configuration command to enable web authentication. You can also use this command in fallback-profile mode. Use the no form of this command to disable web authentication.

The ip admission command applies a web authentication rule to a switch port. This example shows how to apply a web authentication rule to a switchport:. This example shows how to apply a web authentication rule to a fallback profile for use on an IEEE Use the ip admission name proxy http global configuration command to enable web authentication. The ip admission name proxy http command globally enables web authentication on a switch.

After you enable web authentication on a switch, use the ip access-group in and ip admission web-rule interface configuration commands to enable web authentication on a specific interface.

This example shows how to configure only web authentication on a switchport:. Use the show fallback profile privileged EXEC command to display the fallback profiles that are configured on a switch. Optional Append redirected output to a specified URL.

Optional Display begins with the line that matches the expression. Optional Display excludes lines that match the expression. Optional Display includes lines that match the specified expression. Expression in the output to use as a reference point.

Use the show fallback profile privileged EXEC command to display profiles that are configured on the switch. Expressions are case sensitive. For example, if you enter exclude output , the lines that contain output are not displayed, but the lines that contain Output are displayed. This is an example of output from the show fallback profile command:.

The Express Setup configuration windows were updated in the getting started guide. This is the complete procedure:. When you first set up the switch, you should use Express Setup to enter the initial IP information. This enables the switch to connect to local routers and the Internet.

You can then access the switch through the IP address for further configuration. Power the switch by connecting the supplied AC power cord to the switch power connector and to a grounded AC outlet. When the switch powers on, it begins the power-on self-test POST. Wait for the switch to complete POST, which can take several minutes. POST errors are usually fatal. Press and hold the Mode button for 3 seconds. If the LEDs left of the Mode button begin to blink after you press the button, release it.

Blinking LEDs mean that the switch has already been configured and cannot go into Express Setup mode. Connect the other end of the cable to the Ethernet port on your PC. Start a web browser on your PC. Enter the IP address The Express Setup page appears. Enter this information in the Network Settings fields:. Optional You can enter the Optional Settings information now or enter it later by using the device manager interface:. Optional Click the Advanced Settings tab on the Express Setup window, and enter the advanced settings now or enter them later by using the device manager interface.

Optional Enter this information in the Advanced Setting fields:. To complete Express Setup, click Submit from the Basic Settings or the Advanced Settings tab to save your settings, or click Cancel to clear your settings. When you click Submit , the switch is configured and exits Express Setup mode. The PC displays a warning message and tries to connect with the new switch IP address.

If you configured the switch with an IP address that is in a different subnet from the PC, connectivity between the PC and the switch is lost. Disconnect the switch from the PC, and install the switch in your production network. This information was added to the Regulatory Compliance and Safety Information for the Catalyst , , , and switches.
