CNA Compatibility
Cisco IOS Release 12.2(40)EX2 and later is only compatible with Cisco Network Assistant 5.0 and later. You can download Network Assistant from this URL:
http://www.cisco.com/go/networkassistant
For more information about Cisco Network Assistant, see the Release Notes for Cisco Network Assistant on Cisco.com.
Upgrading the Switch Module Software
These are the procedures for downloading software. Before downloading software, read this section for important information:
•"Finding the Software Version and Feature Set" section
•"Deciding Which Files to Use" section
•"Upgrading a Switch Module by Using the Device Manager or Network Assistant" section
•"Upgrading a Switch Module by Using the CLI" section
•"Recovering from a Software Failure" section
Finding the Software Version and Feature Set
The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release. 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 module. The second line of the display shows the version.
Note Although the show version output always shows the software image running on the switch module, the model name at the end of this display is the factory configuration (IP base feature set or IP services feature set). It does not change if you upgrade the software license.
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.
Deciding Which Files to Use
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 module through the device manager. To upgrade the switch module through the command-line interface (CLI), use the tar file and the archive download-sw or archive download privileged EXEC command.
Table 4 lists the filenames for this software release.
The universal software images support multiple feature sets. Use the software activation feature to deploy a software license and to enable a specific feature set. For information about software activation, see the Cisco Software Activation for IBM document on Cisco.com:
http://www.cisco.com/en/US/products/ps8741/products_installation_and_configuration_guides_list.html
Archiving Software Images
Before upgrading your switch module software, make sure that you have archived copies of the current Cisco IOS release and the Cisco IOS release from which you are upgrading. You should keep these archived images until you have upgraded all network devices to the new Cisco IOS image and until you have verified that the new Cisco IOS image works properly.
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.
Note Although you can copy any file on the flash memory to the TFTP server, it is time-consuming to copy all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and archive it on an internal host in your network.
You can also configure the switch module as a TFTP server to copy files from one switch module to another without using an external TFTP server by using the tftp-server global configuration command. For more information about the tftp-server command, see the "Basic File Transfer Services Commands" section of the Cisco IOS Configuration Fundamentals Command Reference, Release 12.2, at this URL:
http://www.cisco.com/en/US/docs/ios/12_2/configfun/command/reference/ffun_r.html
Upgrading a Switch Module by Using the Device Manager or Network Assistant
You can upgrade switch module software by using the device manager or Network Assistant. For detailed instructions, click Help.
Note When using the device manager to upgrade your switch module, do not use or close your browser session after the upgrade process begins. Wait until after the upgrade process completes.
Upgrading a Switch Module by Using the CLI
This procedure is for copying the combined tar file to the switch module. You copy the file to the switch module from a TFTP server and extract the files. You can download an image file and replace or keep the current image.
To download software, follow these steps:
Step 1 Use Table 4 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:
http://www.cisco.com/kobayashi/sw-center/sw-lan.shtml
To download the universal software image files for a switch module, click Cisco Catalyst Blade Switch 3000 Series for IBM.
Step 3 Copy the image to the appropriate TFTP directory on the workstation, and make sure that the TFTP server is properly configured.
For more information, see Appendix B in the software configuration guide for this release.
Step 4 Log into the switch module through the console port or a Telnet session.
Step 5 (Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC command:
Switch# ping tftp-server-address
For more information about assigning an IP address and default gateway to the switch module, see the software configuration guide for this release.
Step 6 Download the image file from the TFTP server to the switch module. If you are installing the same version of software that is currently on the switch module, overwrite the current image by entering this privileged EXEC command:
Switch# archive download-sw /overwrite /reload tftp:[[//location]/directory]/image-name.tarThe /overwrite option overwrites the software image in flash memory with the downloaded one.
The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved.
For //location, specify the IP address of the TFTP server.
For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive.
This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite the image on the switch module:
Switch# archive download-sw /overwrite tftp://198.30.20.19/cbs31x0-universal-tar.122-40.EX.tarYou can also download the image file from the TFTP server to the switch module and keep the current image by replacing the /overwrite option with the /leave-old-sw option.
Recovering from a Software Failure
For additional recovery procedures, see the "Troubleshooting" chapter in the software configuration guide for this release.
Installation Notes
You can assign IP information to your switch module by using the IBM advanced Management Module software and the switch module device manager Express Setup program, as described in the switch module getting started guide.
New Features
These sections describe the new supported hardware and the new and updated software features provided in this release:
•"New Hardware Features" section
•"New Software Features" section
New Hardware Features
For a list of all supported hardware, see the "Hardware Supported" section.
New Software Features
•Full QoS support for IPv6 traffic.
•Smart Install to allow a single point of management (director) in a network. You can use Smart Install to provide zero touch image and configuration upgrade of newly deployed switches and image and configuration downloads for any client switches.
•Cisco Medianet to enable intelligent services in the network infrastructure for a wide variety of video applications. One of the services of Medianet is auto provisioning for Cisco Digital Media Players and Cisco IP Video Surveillance cameras through Auto Smartports.
•Support for IP source guard on static hosts.
•RADIUS Change of Authorization (CoA) to change the attributes of a certain session after it is authenticated. When there is a change in policy for a user or user group in AAA, administrators can send the RADIUS CoA packets from the AAA server, such as Cisco Secure ACS to reinitialize authentication, and apply to the new policies.
•IEEE 802.1x User Distribution to allow deployments with multiple VLANs (for a group of users) to improve scalability of the network by load balancing users across different VLANs. Authorized users are assigned to the least populated VLAN in the group, assigned by RADIUS server.
•Support for critical VLAN with multiple-host authentication so that when a port is configured for multi-auth, and an AAA server becomes unreachable, the port is placed in a critical VLAN in order to still permit access to critical resources.
•Customizable web authentication enhancement to allow the creation of user-defined login, success, failure and expire web pages for local web authentication.
•Support for Network Edge Access Topology (NEAT) to change the port host mode and to apply a standard port configuration on the authenticator switch port.
•VLAN-ID based MAC authentication to use the combined VLAN and MAC address information for user authentication to prevent network access from unauthorized VLANs.
•MAC move to allow hosts (including the hosts connected behind an IP phone) to move across ports within the same switch without any restrictions to enable mobility. With MAC move, the switch treats the reappearance of the same MAC address on another port in the same way as a completely new MAC address.
•Support for including a hostname in the option 12 field of DHCPDISCOVER packets. This provides identical configuration files to be sent by using the DHCP protocol.
•DHCP snooping enhancement to support the selection of a fixed string-based format for the circuit-id sub-option of the Option 82 DHCP field.
•Support for VTP version 3 that includes support for configuring extended range VLANs (VLANs 1006 to 4094) in any VTP mode, enhanced authentication (hidden or secret passwords), propagation of other databases in addition to VTP, VTP primary and secondary servers, and the option to turn VTP on or off by port.
•Support for the LLPD-MED MIB and the CISCO-ADMISSION-POLICY-MIB.
•Support for up to 32 10 Gigabit Ethernet DWDM X2 optical modules.
Minimum Cisco IOS Release for Major Features
Table 5 lists the minimum software release (after the first release) required to support the major features of the Catalyst Switch Module 3110G, 3110X, and 3012. Features not listed are supported in all releases.
Limitations and Restrictions
You should review this section before you begin working with the switch module. 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 module hardware or software.
This section contains these limitations:
•"Cisco IOS Limitations" section
•"Device Manager Limitations" section
•"IBM BladeCenter Advanced Management Module Limitations" section
Cisco IOS Limitations
Unless otherwise noted, these limitations apply to the Catalyst Switch Module 3110G, 3110X, and 3012:
•"Access Control List" section
•"Address Resolution Protocol" section
•"Cisco X2 Transceiver Modules" section
•"IEEE 802.1x Authentication" section
Access Control List
This is the access control list (ACL) limitation:
When a MAC access list is used to block packets from a specific source MAC address, that MAC address is entered in the switch module MAC-address table.
The workaround is to block traffic from the specific MAC address by using the mac address-table static mac-addr vlan vlan-id drop global configuration command. (CSCse73823)
Address Resolution Protocol
This is an Address Resolution Protocol limitation:
The switch module might place a port in an error-disabled state due to an Address Resolution Protocol (ARP) rate limit exception even when the ARP traffic on the port is not exceeding the configured limit. This could happen when the burst interval setting is 1 second, the default.
The workaround is to set the burst interval to more than 1 second. We recommend setting the burst interval to 3 seconds even if you are not experiencing this problem.(CSCse06827))
Cisco X2 Transceiver Modules
These are the Cisco X2 transceiver module limitations:
•Cisco X2-10GB-CX4 transceiver modules with a version identification number lower than V03 might be difficult to install because of a size discrepancy. The workaround is to use modules with a version identification number of V03 or later. (CSCsg28558)
•Switch modules with the Cisco X2-10GB-LX4 transceiver modules with a version identification number before V03 might intermittently fail. The workaround is to use Cisco X2-10GB-LX4 transceiver modules with a version identification number of V03 or later. (CSCsh60076)
•When a Cisco X2-10GB-CX4 transceiver module is in the X2 transceiver module port and you enter the show controllers ethernet-controller tengigabitethernet privileged EXEC command, the command displays some fields as unspecified. This is the expected behavior, based IEEE 802.3ae. (CSCsd47344)
Configuration
These are the configuration limitations:
•When an excessive number (more than 100 packets per second) of Address Resolution Protocol (ARP) packets are sent to a Network Admission Control (NAC) Layer 2 IP-configured member port, a switch module might display a message similar to this:
PLATFORM_RPC-3-MSG_THROTTLED: RPC Msg Dropped by throttle mechanism: type 0, class 51, max_msg 128, total throttled 984323
-Traceback= 6625EC 5DB4C0 5DAA98 55CA80 A2F2E0 A268D8
No workaround is necessary. Under normal conditions, the switch module generates this notification when snooping the next ARP packet. (CSCse47548)
•When there is a VLAN with protected ports configured in a fallback bridge group, packets might not be forwarded between the protected ports.
The workaround is to not configure VLANs with protected ports as part of a fallback bridge group. (CSCsg40322)
•When a switch module port configuration is set at 10 Mb/s and half duplex, sometimes the port does not send in one direction until the port traffic is stopped and then restarted. You can detect the condition by using the show controller ethernet-controller or the show interfaces privileged EXEC commands.
The workaround is to stop the traffic in the direction in which it is not being forwarded, and then restart it after 2 seconds. You can also use the shutdown interface configuration command followed by the no shutdown command on the interface. (CSCsh04301)
•The switch module might display tracebacks similar to this example when an EtherChannel interface port-channel type changes from Layer 2 to Layer 3 or the reverse:
15:50:11: %COMMON_FIB-4-FIBNULLHWIDB: Missing hwidb for fibhwidb Port-channel1 (ifindex 1632) -Traceback= A585C B881B8 B891CC 2F4F70 5550E8 564EAC 851338 84AF0C 4CEB50 859DF4 A7BF28 A98260 882658 879A58
There is no workaround. (CSCsh12472)
•When line rate traffic is passing through a dynamic port, and you enter the switchport access vlan dynamic interface configuration command for a range of ports, the VLANs might not be assigned correctly. One or more VLANs with a null ID appears in the MAC address table instead.
The workaround is to enter the switchport access vlan dynamic interface configuration command separately on each port.(CSCsi26392)
•(Only Catalyst Switch Module 3110G and 3012) These privileged EXEC commands incorrectly display the internal, nonconfigurable Gigabit Ethernet interfaces n/0/19 and n/0/20.
show mls qos interfaceshow mls qos interface buffersshow mls qos interface policersshow mls qos interface queueingshow mls qos interface statisticsshow mac access-groupshow controllers ethernet-controllershow interfaces Gin/0/19 [all options]show idb allThere is no workaround. (CSCsk51772)
•If there is large-volume bidirectional traffic on the switch module Fa0 management interface, some packets might be dropped because of CPU limitations. This is not a likely occurrence because the Fa0 interface typically does not send or receive large-volume traffic.
There is no workaround. (CSCso35380)
•(Only Catalyst Switch Module 3110X) If you configure port security on Gigabit Ethernet interface n/0/14, the switch module software incorrectly allows the configuration. Port security is not supported on Gigabit Ethernet interface n/0/14.
There is no workaround. (CSCso75068)
•If you enter the show tech-support privileged EXEC command after you enter the remote command {all | stack-member-number} privileged EXEC command, the complete output does not appear.
The workaround is to use the session stack-member-number privileged EXEC command. (CSCsz38090)
IEEE 802.1x Authentication
These are the IEEE 802.1x authentication limitations:
•If a supplicant using a Marvel Yukon network interface card (NIC) is connected an IEEE 802.1x-authorized port in multihost mode, the extra MAC address of 0c00.0000.0000 appears in the MAC address table.
Use one of these workarounds (CSCsd90495):
–Configure the port for single-host mode to prevent the extra MAC address from appearing in the MAC address table.
–Replace the NIC with a new card.
•When MAC authentication bypass is configured to use Extensible Authentication Protocol (EAP) for authorization and critical authentication is configured to assign a critical port to an access VLAN:
–If the connected device is supposed to be unauthorized, the connected device might be authorized on the VLAN that is assigned to the critical port instead of to a guest VLAN.
–If the device is supposed to be authorized, it is authorized on the VLAN that is assigned to the critical port.
Use one of these workarounds (CSCse04534):
–Configure MAC authentication bypass to not use EAP.
–Define your network access profiles to not use MAC authentication bypass. For more information, see the Cisco Access Control Server (ACS) documentation.
Multicasting
These are the multicasting limitations:
•Multicast packets with a time-to-live (TTL) value of 0 or 1 are flooded in the incoming VLAN when all of these conditions are met:
–Multicast routing is enabled in the VLAN.
–The source IP address of the packet belongs to the directly connected network.
–The TTL value is either 0 or 1.
The workaround is to not generate multicast packets with a TTL value of 0 or 1 or to disable multicast routing in the VLAN. (CSCeh21660)
•Multicast packets denied by the multicast boundary access list are flooded in the incoming VLAN when all of these conditions are met:
–Multicast routing is enabled in the VLAN.
–The source IP address of the multicast packet belongs to a directly connected network.
–The packet is denied by the IP multicast boundary access-list configured on the VLAN.
There is no workaround. (CSCei08359)
•Reverse path forwarding (RPF) failed multicast traffic might cause a flood of Protocol Independent Multicast (PIM) messages in the VLAN when a packet source IP address is not reachable.
The workaround is to not send RPF-failed multicast traffic, or make sure that the source IP address of the RPF-failed packet is reachable. (CSCsd28944)
•If you use the clear ip mroute privileged EXEC command when multicast packets are present, it might cause temporary flooding of incoming multicast traffic in the VLAN.
There is no workaround. (CSCsd45753)
•When you configure the ip igmp max-groups number and ip igmp max-groups action replace interface configuration commands and the number of reports exceed the configured max-groups value, the number of groups might temporarily exceed the configured max-groups value. No workaround is necessary. The problem corrects itself when the rate or number of IGMP reports are reduced. (CSCse27757)
QoS
These are the quality of service (QoS) limitations:
•When QoS is enabled and the egress port receives pause frames at the line rate, the port cannot send packets.
There is no workaround. (CSCeh18677)
•Egress shaped round robin (SRR) sharing weights do not work properly with system jumbo MTU frames.
There is no workaround. (CSCsc63334)
•In a hierarchical policy map, if the VLAN-level policy map is attached to a VLAN interface and the name of the interface-level policy map is the same as that for another VLAN-level policy map, the switch module rejects the configuration. The VLAN-level policy map is removed from the interface.
The workaround is to use a different name for the interface-level policy map. (CSCsd84001)
•If the ingress queue has low buffer settings and the switch module sends multiple data streams of system jumbo MTU frames at the same time at the line rate, the frames are dropped at the ingress.
There is no workaround. (CSCsd72001)
•When you use the srr-queue bandwidth limit interface configuration command to limit port bandwidth, packets that are less than 256 bytes can cause inaccurate port bandwidth readings. The accuracy improves when the packet size is greater than 512 bytes.
There is no workaround. (CSCsg79627)
•If QoS is enabled on a switch and the switch has a high volume of incoming packets with a maximum transmission unit (MTU) size greater than 1512 bytes, the switch might reload.
Use one of these workarounds:
–Use the default buffer size.
–Use the mls qos queue-set output qset-id buffers allocation1 ... allocation4 global configuration command to allocate the buffer size. The buffer space for each queue must be at least 10 percent. (CSCsx69718)
RADIUS
This is the RADIUS limitation:
RADIUS change of authorization (COA) reauthorization is not supported on the critical auth VLAN.
There is no workaround. (CSCta05071)
Routing
This is the routing limitation:
When the PBR is enabled and QoS is enabled with DSCP settings, the CPU usage might be high if traffic is sent to unknown destinations.
The workaround is to not send traffic to unknown destinations. (CSCse97660)
Stacking
This is the stacking limitation:
Creating a mixed switch stack with a Catalyst Switch Module 3110, a Catalyst Switch Module 3120, or a Catalyst Switch Module 3130 produces unpredictable behavior and could cause a system failure. Because the switch module software does not detect this type of configuration, it allows a stack of this type.
There is no workaround. This is not a supported configuration. (CSCsj44478)
SPAN and RSPAN
These are the SPAN and Remote SPAN (RSPAN) limitations.
•When egress SPAN is running on a 10-Gigabit Ethernet port, only about 12 percent of the egress traffic is monitored.
There is no workaround. This is a hardware limitation. (CSCei10129)
•When the logging event-spanning-tree interface configuration command is configured and logging to the console is enabled, a topology change might generate a large number of logging messages, causing high CPU usage. CPU usage can increase with the number of spanning-tree instances and the number of interfaces configured with the logging event-spanning-tree interface configuration command. This condition adversely affects how the switch module operates and could cause problems such as STP convergence delay.
High CPU usage can also occur with other conditions, such as when debug messages are logged at a high rate to the console.
Use one of these workarounds (CSCsg91027):
–Disable logging to the console.
–Rate-limit logging messages to the console.
–Remove the logging event spanning-tree interface configuration command from the interfaces.
Device Manager Limitations
This is the device manager limitation:
When you are prompted to accept the security certificate and you click No, you only see a blank screen, and the device manager does not start.
The workaround is to click Yes when you are prompted to accept the certificate. (CSCef45718)
IBM BladeCenter Advanced Management Module Limitations
This is the advanced Management Module (aMM) limitation:
When a switch module is installed in a BC-HT chassis with the ISL Interposer, the switch module incorrectly reports that it is installed in a BC-T chassis and that it provides 8 server ports and no ISL ports. When it is installed with the non-ISL Interposers, the switch module incorrectly reports that it is installed in a BC-H chassis and that it provides 14 server ports.
See the IBM Retain database for more information.
Important Notes
These sections describe the important notes related to this software release for the Catalyst Switch Module 3110G, 3110X, and 3012:
•"Device Manager Notes" section
Cisco IOS Notes
This note applies to Cisco IOS software:
If the switch module requests information from the Cisco Secure Access Control Server (ACS) and the message exchange times out because the server does not respond, a message similar to this appears:
00:02:57: %RADIUS-4-RADIUS_DEAD: RADIUS server 172.20.246.206:1645,1646 is not responding.If this message appears, make sure that there is network connectivity between the switch module and the ACS. You should also make sure that the switch module has been properly configured as an AAA client on the ACS.
Device Manager Notes
These notes apply to the device manager:
•You cannot create and manage switch module clusters through the device manager. To create and manage switch module clusters, use the CLI or Cisco Network Assistant.
•When the switch module is running a localized version of the device manager, the switch module displays settings and status only in English letters. Input entries on the switch module can only be in English letters.
•For device manager session on Internet Explorer, popup messages in Japanese or in simplified Chinese can appear as garbled text. These messages appear properly if your operating system is in Japanese or Chinese.
•We recommend this browser setting to reduce the time needed to display the device manager from Microsoft Internet Explorer.
From Microsoft Internet Explorer:
1. Choose Tools > Internet Options.
2. Click Settings in the "Temporary Internet files" area.
3. From the Settings window, choose Automatically.
4. Click OK.
5. Click OK to exit the Internet Options window.
•The HTTP server interface must be enabled to display the device manager. By default, the HTTP server is enabled on the switch module. Use the show running-config privileged EXEC command to see if the HTTP server is enabled or disabled.
Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:
•The device manager uses HTTP (the default is port 80) and the default method of authentication (the enable password) to communicate with the switch module through any of its Ethernet ports and to allow switch module management from a standard web browser.
If you change the HTTP port, you must include the new port number when you enter the IP address in the browser Location or Address field (for example, http://10.1.126.45:184 where 184 is the new HTTP port number). You should write down the port number through which you are connected. Use care when changing the switch module 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 module.
Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:
If you use Internet Explorer Version 5.5 and select a URL with a nonstandard port at the end of the address (for example, www.cisco.com:84), you must enter http:// as the URL prefix. Otherwise, you cannot launch the device manager.
Open Caveats
Unless otherwise noted, these Cisco IOS configuration caveats apply to the Catalyst Switch Module 3110G, 3110X, and 3012:
•CSCsy85676
When you configure an ACL and enter the access-group interface configuration command to apply it to an interface for web authentication, the output from the show epm session ip-address or show ip access_list interface interface-id privileged EXEC command does not show any web authentication filter ID.
There is no workaround.
•CSCsz18634
On a switch running Cisco IOS release 12.2(46)SE, the output of the show interfaces privileged EXEC command shows 0 packets for port channel input and output rates.
The workaround is to reload the switch by entering the reload privileged EXEC command.
•CSCtb08823
SNMP requests on the stpxRSTPPortRoleTable object only return information for the stack master.
There is no workaround.
•CSCtb25230
When a switch stack is configured with DHCP snooping enabled on the host VLAN, hosts connected to the stack master receive bootp packets, but the a packet might not be forwarded to the end hosts connected to stack member switches. The behavior depends on which interface in the stack received the packet.
The workaround is to disable DHCP snooping for the affected VLAN.
•CSCtb88425
If you press the MODE button to enter Express Setup setup mode after the switch has received an IP address dynamically through DHCP, HTTP authentication with the default username and password cisco/cisco fails.
Use one of these workarounds:
–Downgrade the image to 12.2(46)SE where there is no HTTP authentication.

•CSCtc02635
On switches running Cisco IOS release 12.2(50)SE3 running MAC authentication bypass with multidomain authentication (MDA, IP phones connected to a port might not be able to regain network connectivity in the VOICE domain if the session times out and all RADIUS servers are unreachable.
There is no workaround.
Resolved Caveats
This release resolves these previously open caveats:
•CSCso35214
When you remove a switch module from a switch stack, the switch module Fa0 management interface remains administratively down and cannot be enabled by using the CLI.
The workaround is to reload the switch module.
•CSCso43123
(Only Catalyst Switch Module 3110X) When you move a blade server installed in slot 14 to another blade enclosure slot and install a new server in slot 14, unicast traffic from the original server to the new server might not be forwarded.
No workaround is needed. The problem corrects itself when the dynamic MAC address learning period times out. The default timeout is 5 minutes and is configurable in the CLI.
•CSCsw68528
On switches running Cisco IOS Release 12.2(44)SE or 12.2(46)SE, when you enter the show mvr interface interface-id members privileged EXEC command to see status of an MVR port, an MVR member port that is not connected always shows as ACTIVE.
The workaround is to use the show mvr interface interface-id or the show mvr members privileged EXEC command. These command outputs show the correct status of an MVR port.
•CSCsw69015
When you enter the mvr vlan vlan-id global configuration command to create an MVR VLAN and enable MVR on the switch by entering the mvr global configuration command, if you enter the show mvr interface interface-id members privileged EXEC command, the output shows the MVR groups on the interface. However, if you enable MVR first and then create the MVR VLAN, the MVR groups are not displayed correctly.
•CSCsw69335
In a stacked environment, IP ACLs are not applied to interfaces on member switches unless IP routing is enabled.
The workaround when applying IP ACLs to stack member interfaces is to enable IP routing on the stack master by entering the ip routing global configuration command.
•CSCsw96933
A switch running Cisco IOS Release 12.2(46)SE might lose packets for up to 30 seconds when a link fails. This occurs in some multiple spanning-tree (MST) topologies.
There is no workaround.
•CSCsx34798
The management port (Fa0) is shut down when a Telnet session is opened on the port from the chassis GUI. This occurs when the switch is in a stack and the stack members are powered down by using the chassis GUI.
The workaround is to reload the switch.
•CSCsx44525
If a Advanced Management Module (AMM) acts as a fail-over backup to another AMM, the ARP tables are not populated correctly.
There is no workaround.
•CSCsx71632
When VLAN-based quality of service (QoS) is enabled and then disabled on an interface by entering the mls qos vlan-based interface configuration command followed by the no version of the command, the port policy is not applied properly and could result in undefined behavior for packets matching the port policy.
The workaround is to remove the port policy by entering the no service-policy input policy-map-name interface configuration command and then reapply it to the interface.
•CSCsx78068
If you enable 802.1Q native VLAN tagging by entering the vlan dot1q tag native global configuration command and then change the native VLAN ID on an ingress trunk port by entering the switchport trunk native vlan vlan-id interface command, untagged traffic is forwarded instead of being dropped.
The workaround is to use one of these methods:
–Enter a shutdown followed by a no shutdown interface configuration command on the trunk port.
–Disable and then reenable native VLAN tagging by entering the no vlan dot1q tag native global configuration command followed by the vlan dot1q tag native command.
•CSCsy90265
If you repeatedly enter the show tech-support privileged EXEC command, the switch might leak memory and, in some cases, shut down.
The workaround is to reload the switch to clear the memory after repeated use of the show tech-support command.
•CSCsz66428
When flow control is enabled on a port-channel interface and you enter the flowcontrol receive on interface configuration command, the bundle is not enabled after the switch restarts. The command appears in the port-channel interface running configuration but does not appear in the switch running configuration. A message such as this appears:
%EC-5-CANNOT_BUNDLE2: Gi0/27 is not compatible with Po1 and will be suspended (flow control receive of Gi0/27 is on, Po1 is off)%EC-5-CANNOT_BUNDLE2: Gi0/28 is not compatible with Po1 and will be suspended (flow control receive of Gi0/28 is on, Po1 is off)Use one of these workarounds:
–To manually configure the port-channel interface, enter the flowcontrol receive on interface configuration command.
–To add the flow-control configuration to the interface after the switch restarts, use an EEM script similar to this:
event manager applet Add_flowcontrol_on_restartevent syslog pattern SYS-5-RESTARTaction 1 cli command "en"action 2 cli command "conf t"action 3 cli command "inter port 1"action 4 cli command "flowcontrol receive on"For action 3, specify the port-channel interface.
•CSCsz72234
In a VPN routing/forwarding (VRF) instance, a port channel is configured, and the default route is in the global routing table. If a link shuts down while the other links remain up, the port channel might not forward traffic.
Use one of these workarounds:
–Enter the shutdown interface configuration command, and then enter the no shutdown interface command.
–In the VRF instance, configure the links in the port channel as Layer 2 access links, and configure a switch virtual interface (SVI).
•CSCsz88857
When an interface on the stack master is a member of an EtherChannel and the channel group number is removed before a master switch changeover, you can not use the same group number when you recreate the EtherChannel after the changeover.
These are possible workarounds:
–Reload the switches in the EtherChannel into the channel group that you were not able to create.
–Use a new channel group number to bundle the physical interfaces in an EtherChannel.
–Reconfigure the EtherChannel before the master switch changeover.
•CSCsy89011
Communication between the blade switch and blade server breaks after upgrading the switch from 12.2(40)EX2 to 12.2(46)SE under these conditions:
–mac-address-table on the switch does not show the internal host MAC.
–When we ping the internal host IP from the switch console, the ping fails leaving temporary ARP entry for the IP with incomplete mac-address.
The workaround is to disable the native vlan tagging feature and then do 'shut' and 'no shut' on the interface.
•CSCta10012
The user saw the error message about port 20 as following:
027562: Jun 3 12:29:38.357 PDT: %CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on GigabitEthernet0/20 (1), with RCOBC01 GigabitEthernet0/20 (1002).On the blade switch 3012 switch, we can only see 18 ports. Logged from the management console and port 20 can not be modified as well
The workaround is to reload the switch that shows native VLAN in the message
•CSCta53893
If the host is in multiple-authentication (multiauth) mode and you configure the fallback authentication process as IEEE 802.1x or MAc authentication bypass, the per-user ACL does not work when the port uses web authentication as the fallback method and then uses 802.1x or MAC authentication bypass as the fallback method.
The workaround is to restart the switch.
•CSCta57846
The switch unexpectedly reloads when copying a configuration file from a remote server or from flash memory containing logging file flash:
The workaround is to enter the logging file flash:filename global configuration command to configure logging to flash instead of copying to flash.
•CSCta61664
Speed auto negotiation is turned "off" on the other side.
Workaround: Speed auto negotiation is turned "on" on the other side.
•CSCta78502
When you have configured a login banner by entering the banner login c message c global configuration command and the switch reloads, the output of banner is missing a carriage return, making the format incorrect.
There is no workaround.
•CSCta80514
When you enable MAC address learning on a VLAN and then change the interface configuration (such as adding the VLAN to the list of VLANs allowed on a trunk), MAC address learning is not disabled on the interface. If you disable MAC address learning on the switch, high CPU utilization occurs when the local forwarding manager tries to ut does not learn MAC addresses.
There is no workaround.
•CSCtb54305
You cannot configure private VLANs on port 14 on the Cisco Catalyst Switch Module 3110X.
There is no workaround.
•CSCtb77378
When you use IEEE 802.1x authentication with web authentication and an HTTP page opens, the switch redirects the user to an HTTP login page, not a HTTPS login page.
The workaround is to remove the custom banner.
•CSCtb84303
In a switch stack, when the SNMP vlan change (vmMembershipEntry) MIB is sent to a member switch other than the stack master, line protocol and notification flapping occurs.
There is no workaround.
•CSCtb97439
When remote neighbors change, the LLDP MIB does not properly update the remote neighbors.
The workaround is to clear the LLDP table by entering the clear lldp table privileged EXEC command.

Update to the "Configuring IEEE 802.1x Port-Based Authentication" Chapter
Common Session ID
Authentication manager uses a single session ID (referred to as a common session ID) for a client no matter which authentication method is used. This ID is used for all reporting purposes, such as the show commands and MIBs. The session ID appears with all per-session syslog messages.
The session ID includes:
•The IP address of the Network Access Device (NAD)
•A monotonically increasing unique 32 bit integer
•The session start time stamp (a 32 bit integer)
This example shows how the session ID appears in the output of the show authentication command. The session ID in this example is 160000050000000B288508E5:
Switch# show authentication sessions
Interface MAC Address Method Domain Status Session IDFa4/0/4 0000.0000.0203 mab DATA Authz Success 160000050000000B288508E5This is an example of how the session ID appears in the syslog output. The session ID in this example is also160000050000000B288508E5:
1w0d: %AUTHMGR-5-START: Starting 'mab' for client (0000.0000.0203) on Interface Fa4/0/4 AuditSessionID 160000050000000B288508E51w0d: %MAB-5-SUCCESS: Authentication successful for client (0000.0000.0203) on Interface Fa4/0/4 AuditSessionID 160000050000000B288508E51w0d: %AUTHMGR-7-RESULT: Authentication result 'success' from 'mab' for client (0000.0000.0203) on Interface Fa4/0/4 AuditSessionID 160000050000000B288508E5The session ID is used by the NAD, the AAA server, and other report-analyzing applications to identify the client. The ID appears automatically. No configuration is required.
Update to the "Configuring Embedded Event Manager" Chapter
Embedded Event Manager 3.2
Embedded Event Manager (EEM) is a distributed and customized approach to event detection and recovery offered directly in a Cisco IOS device. EEM offers the ability to monitor events and take informational, corrective, or any desired EEM action when the monitored events occur or when a threshold is reached. An EEM policy is an entity that defines an event and the actions to be taken when that event occurs.
EEM 3.2 is supported in Cisco IOS Release 12.2(52)SE and later releases, and introduced many new features.
EEM 3.2 introduces the following new event detectors:
•Neighbor Discovery—Neighbor Discovery event detector provides the ability to publish a policy to respond to automatic neighbor detection when:
–a Cisco Discovery Protocol (CDP) cache entry is added, deletedn or updated.
–a Link Layer Discovery Protocol (LLDP) cache entry is added, deleted, or updated.
–an interface link status changes.
–an interface line status changes.
•Identity—Identity event detector generates an event when AAA authorization and authentication is successful, when failure occurs, or after normal user traffic on the port is allowed to flow.
•Mac-Address-Table—Mac-Address-Table event detector generates an event when a MAC address is learned in the MAC address table.
Note The Mac-Address-Table event detector is supported only on switch platforms and can be used only on Layer 2 interfaces where MAC addresses are learned. Layer 3 interfaces do not learn addresses and routers do not usually support the mac-address-table infrastructure needed to notify EEM of a learned MAC address.
EEM 3.2 also introduces new CLI commands to support the applets to work with the new event detectors.
For further details about EEM 3.2 features, see the Embedded Event Manager 3.2 document.
