Upgrading the Switch Software
These are the procedures for downloading software. Before downloading software, read this section for important information:

•
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. The second line of the display shows the version.
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 through the device manager. To upgrade the switch through the command-line interface (CLI), use the tar file and the archive download-sw privileged EXEC command.
Note
Table 3 lists the filenames for this software release.
Archiving Software Images
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.
Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for more information:
http://www.cisco.com/en/US/products/sw/iosswrel/ps5187/prod_bulletin0900aecd80281c0e.html
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
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. 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:
Upgrading a Switch by Using the Device Manager
You can upgrade switch software by using the device manager. For detailed instructions, click Help.
Note
Upgrading a Switch by Using the CLI
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.
To download software, follow these steps:
Step 1
Step 2
http://www.cisco.com/public/sw-center/sw-lan.shtml
Step 3
For more information, see Appendix B in the software configuration guide for this release.
Step 4
Step 5
Switch# ping tftp-server-addressFor more information about assigning an IP address and default gateway to the switch, see the software configuration guide for this release.
Step 6
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:
Switch# archive download-sw /overwrite tftp://198.30.20.19/c3750-ipservices-tar.122-44.SE.tarYou can also download the image file from the TFTP server to the switch and keep the current image by replacing the /overwrite option with the /leave-old-sw option.

New Software Features
These are the new software features for this release:
•
•
•
•
•
•
•
•
Limitations and Restrictions
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.
This section contains these limitations:
•
•
Cisco IOS Limitations
These limitations apply to the switch:
•
•
Configuration
•
This problem occurs under these conditions:
–
–
–
The workaround is to reconfigure the static IP address. (CSCea71176 and CSCdz11708)
•
The workaround is to configure the port for 10 Mp/s and half duplex or to connect a hub or a nonaffected device to the switch. (CSCed39091)
•
The workaround is to enter the no switchport block unicast interface configuration command on that specific interface. (CSCee93822)
•
There is no workaround. This is a cosmetic error and does not affect the functionality of the switch. (CSCef59331)
Dynamic ARP Inspection
When dynamic ARP inspection is configured on a VLAN, and the ARP traffic on a port in the VLAN is within the configured rate limit, the port might go into an error-disabled state. (CSCse06827)
Ethernet
Traffic on EtherChannel ports is not perfectly load-balanced. Egress traffic on EtherChannel ports are distributed to member ports on load balance configuration and traffic characteristics like MAC or IP address. More than one traffic stream might map to same member ports, based on hashing results calculated by the ASIC.
If this happens, traffic distribution is uneven 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 150 distinct incrementing destination IP addresses, and the number of ports in the EtherChannel set to either 2, 4, or 8, load distribution is optimal. (CSCeh81991)
IP
When the rate of received DHCP requests exceeds 2,000 packets per minute for a long time, the response time might be slow when you are using the console. The workaround is to use rate limiting on DHCP traffic to prevent a denial of service attack from occurring. (CSCeb59166)
IP Telephony
After you change the access VLAN on a port that has IEEE 802.1x enabled, the IP phone address is removed. Because learning is restricted on IEEE 802.1x-capable ports, it takes approximately 30 seconds before the address is relearned. No workaround is necessary. This limitation is unlikely to affect the Cisco Catalyst Blade Switch 3040 for FSC because IP phones are not usually connected to the switch uplink ports. (CSCea85312)
MAC Addressing Multicasting
•
•
•
–
–
There is no workaround. (CSCec20128)
•
The switchport block multicast interface configuration command is only applicable to non-IP multicast traffic.
There is no workaround. (CSCee16865)
•
–
–
The workaround is to enter the clear ip mroute privileged EXEC command on the interface. (CSCef42436)
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.
Use one of these workarounds:
–
–
QoS
•
•
•
The workaround is to use policy maps with 62 or fewer policers. (CSCsc59418)
SPAN and RSPAN
•
•
•
Trunking
•
•
•
VLAN
•
The workaround is to reduce the number of VLANs or trunks. (CSCeb31087)
Device Manager Limitations
•
The workaround is to click Yes when you are prompted to accept the certificate. (CSCef45718)
Important Notes
These sections describe the important notes related to this software release:
•
Cisco IOS Notes
These notes apply to Cisco IOS software:
•
•
•
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 and the ACS. You should also make sure that the switch has been properly configured as an AAA client on the ACS.
•
If the switch has interfaces with automatic QoS for voice over IP (VoIP) configured and you upgrade the switch software to Cisco IOS Release 12.2(40)SE (or later), when you enter the auto qos voip cisco-phone interface configuration command on another interface, you might see this message:
AutoQoS Error: ciscophone input service policy was not properly appliedpolicy map AutoQoS-Police-CiscoPhone not configuredIf 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.
Device Manager Notes
These notes apply to the device manager:
•
From Microsoft Internet Explorer:
1.
2.
3.
4.
5.
•
Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:
•
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 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.
Beginning in privileged EXEC mode, follow these steps to configure the HTTP server interface:
•
Open Caveats
This section describes the open severity 3 Cisco IOS configuration caveats with possible unexpected activity in this software release:
•
The switch might display tracebacks similar to these examples when a large number of IEEE 802.1x supplicants try to repeatedly log in and log out.
Examples:
Jan 3 17:54:32 L3A3 307: Jan 3 18:04:13.459: %SM-4-BADEVENT: Event 'eapReq' is invalid for the current state 'auth_bend_idle': dot1x_auth_bend Fa9
Jan 3 17:54:32 L3A3 308: -Traceback= B37A84 18DAB0 2FF6C0 2FF260 8F2B64 8E912C Jan 3 19:06:13 L3A3 309: Jan 3 19:15:54.720: %SM-4-BADEVENT: Event 'eapReq_no_reAuthMax' is invalid for the current ate 'auth_restart': dot1x_auth Fa4
Jan 3 19:06:13 L3A3 310: -Traceback= B37A84 18DAB0 3046F4 302C80 303228 8F2B64 8E912C Jan 3 20:41:44 L3A3 315: .Jan 3 20:51:26.249: %SM-4-BADEVENT: Event 'eapSuccess' is invalid for the current state 'auth_restart': dot1x_auth Fa9
Jan 3 20:41:44 L3A3 316: -Traceback= B37A84 18DAB0 304648 302C80 303228 8F2B64 8E912C
There is no workaround.
•
When IEEE 802.1x is globally disabled on the switch by using the no dot1x system-auth-control global configuration command, some interface level configuration commands, including the dot1x timeout and dot1x mac-auth-bypass commands, become unavailable.
The workaround is to enable the dot1x system-auth-control global configuration command before attempting to configure interface level IEEE 802.1x parameters.
•
The configuration file used for the configuration replacement feature requires the character string end\n at the end of the file. The Windows Notepad text editor does not add the end\n string, and the configuration rollback does not work.
These are the workarounds. (You only need to do one of these.)
–
–
The workaround is to configure routed IPv4 multicast and IPv6 unicast traffic in different switch ports.
•
The switch does not correctly update the entPhysicalChildIndex objects from the ENTITY-MIB, and some of the entPhysicalChildIndex entries are missing from the table. This adversely affects network management applications such as CiscoWorks CiscoView because they cannot manage the switch.
There is no workaround.
•
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.
Resolved Caveats

Cisco IOS Caveats Resolved in Cisco IOS Release 12.2(44)SE6
•
Symptoms: Several features within Cisco IOS software are affected by a crafted UDP packet vulnerability. 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. This advisory is posted at the following link: http://www.cisco.com/warp/public/707/cisco-sa-20090325-udp.shtml.
•
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. A sequence of specially crafted TCP/IP packets could cause any of the following results:
–
–
–
–
Workarounds that mitigate this vulnerability are available in the "workarounds" section of the advisory. The advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090325-ip.shtml
•
When MAC authentication bypass (MAB) authentication fails, a memory leak no longer occurs.
•
When a VLAN is assigned for IEEE 802.1x authentication and no VLAN is assigned for other types of authentication (such as user authentication or reauthentication), the 802.1x VLAN assignment no longer persists across subsequent authentication attempts.
•
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.
Cisco has released free software updates that address this vulnerability.
Several mitigation strategies are outlined in the workarounds section of this advisory.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20090325-tcp.shtml
•
When the switch uses HTTP (web-based) authentication, a memory leak no longer occurs after authorization and policy download.
•
The server side of the Secure Copy (SCP) implementation in Cisco IOS software contains a vulnerability that could allow authenticated users with an attached command-line interface (CLI) view to transfer files to and from a Cisco IOS device that is configured to be an SCP server, regardless of what users are authorized to do, per the CLI view configuration. 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 Cisco IOS SCP server is an optional service that is disabled by default. CLI views are a fundamental component of the Cisco IOS Role-Based CLI Access feature, which is also disabled by default. Devices that are not specifically configured to enable the Cisco IOS SCP server, or that are configured to use it but do not use role-based CLI access, are not affected by this vulnerability.
This vulnerability does not apply to the Cisco IOS SCP client feature.
Cisco has released free software updates that address this vulnerability.
There are no workarounds available for this vulnerability apart from disabling either the SCP server or the CLI view feature if these services are not required by administrators.
This advisory is posted at the following link:
http://www.cisco.com/warp/public/707/cisco-sa-20090325-scp.shtml.

•
A router that is configured for HTTP and voice-based services no longer unexpectedly reloads due to memory corruption.
•
When AAA is enabled and you use the aaa group server radius group-name global configuration command to put the switch in server group configuration mode, entering the server-private command no longer causes the switch to reload.
•
The switch no longer reloads when you use the aaa authentication eou default group radius enable global configuration command to configure an EAP over UDP (EOU) method list.
•
A Cisco IOS device may crash while processing an SSL packet. This can happen during the termination of an SSL-based session. The offending packet is not malformed and is normally received as part of the packet exchange.
Cisco has released free software updates that address this vulnerability.

The switch no longer reloads when you use a Kron command scheduler routine to automatically copy configuration data using the Secure Copy Protocol (SCP). (Kron is a Cisco IOS utility for scheduling non-prompting CLI commands to execute at a later time.)
•
When IGMP snooping is enabled and an EtherChannel member interface fails, the switch no longer stops forwarding multicast traffic on the EtherChannel. In previous releases, this occurred when multicast routing was enabled and the EtherChannel interface was a member of a multicast group not directly connected (that is, the multicast group that did not have the C flag set in the show ip mroute privileged EXEC command output).
•
When a switch is connected to a third-party router through an EtherChannel and the EtherChannel is running in Link Aggregation Control Protocol (LACP) mode, the interfaces in the EtherChannel no longer fail after you enter the switchport trunk native vlan vlan-id interface configuration command to change the native VLAN from VLAN 1 (the default) to a different VLAN ID.
•
When dynamic ARP inspection is enabled and IP validation is disabled, the switch no longer drops ARP requests that have a source address of 0.0.0.0. When you are enabling IP validation, use the allow zeros keyword to allow the 0.0.0.0 source address.
•
When MAC addresses are learned on an EtherChannel port, the addresses are now correctly deleted from the MAC address table.
•
When you configure an IP address on a switch virtual interface (SVI) with DCHP and enable DHCP snooping on the SVI VLAN, the switch SVI can now obtain an IP address.
•
When a VLAN includes multiple MAC addresses, the number of MAC addresses shown in SNMP now matches the output of the show mac-address count vlan vlan-id privileged EXEC command.
•
MAC flap-notification no longer occurs when a switch is running VLAN bridge spanning-tree protocol (STP) and fallback bridging is configured on the VLANs running STP.
•
Multiple Spanning-Tree Protocol (MSTP) convergence time has been improved for Cisco IOS Release 12.2.
•
Changing the spanning tree mode from MSTP to other spanning modes no longer causes tracebacks.
•
The TxBufferFullDropCount counter no longer increments when the switch is a standalone switch.
•
The Total- output-drops field in the show interfaces privileged EXEC command output now displays accurate ASIC drops.
•
If you enter a space before a comma in the define interface-range or the interface range global configuration command, the space before the comma is now saved in the switch configuration.
•
A switch configured for Link Layer Discovery Protocol (LLDP) now correctly reports the enabled switch capabilities in the LLDP type, length, and value (TLV) attributes.
Documentation Updates
This section contains these documentation updates:
•
•
Updates to the Software Configuration Guide
These are the updates to the software configuration guide:
•
When you globally enable BPDU guard on ports that are Port Fast-enabled (the ports are in a Port Fast-operational state), spanning tree shuts down Port Fast-enabled ports that receive BPDUs.
This is the correct information:
When you globally enable BPDU guard on ports that are Port Fast-enabled (the ports are in a Port Fast-operational state), spanning tree continues to run on the ports. They remain up unless they receive a BPDU.
•
After you have entered the eigrp stub router configuration command, only the eigrp stub connected summary command takes effect. Although the CLI help might show the receive-only and static keywords and you can enter these keywords, the switch always behaves as if the connected and summary keywords were configured.
Updates to the System Message Guide
These are the updates to the system message guide:
Error Message VQPCLIENT-2-TOOMANY: Interface [chars] shutdown by active host limit.Explanation The system has shut down the specified interface because too many hosts have requested access to that interface. [chars] is the interface name.
Recommended Action To enable the interface, remove the excess hosts, and enter the no shutdown interface configuration command.
Error Message VQPCLIENT-3-VLANNAME: Invalid VLAN [chars] in response.Explanation The VLAN membership policy server (VMPS) has specified a VLAN name that is unknown to the switch. [chars] is the VLAN name.
Recommended Action Ensure that the VLAN exists on the switch. Verify the VMPS configuration by entering the show vmps privileged EXEC command.
Error Message WCCP-5-CACHEFOUND: Web Cache [IP_address] acquired.Explanation The switch has acquired the specified web cache. [IP_address] is the web cache IP address.
Recommended Action No action is required.
Error Message WCCP-1-CACHELOST: Web Cache [IP_address] lost.Explanation The switch has lost contact with the specified web cache. [IP_address] is the web cache IP address.
Recommended Action Verify the operation of the web cache by entering the show ip wccp web-cache privileged EXEC command.
