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.
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/kobayashi/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.122-25.SED.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.
Recovering from a Software Failure
For additional recovery procedures, see the "Troubleshooting" chapter in the software configuration guide 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 switch:
•
•
Configuration
These are the configuration limitations:
•
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 Mbps 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)
Ethernet
This is the Ethernet limitation:
•
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
This is the IP limitation:
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
These are the IP telephony limitations:
•
•
MAC Addressing Multicasting
These are the multicasting limitations:
•
•
•
–
–
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
These are the quality of service (QoS) limitations:
•
•
SPAN and RSPAN
These are the SPAN and Remote SPAN (RSPAN) limitations.
•
•
•
Trunking
These are the trunking limitations:
•
•
•
VLAN
This is the VLAN limitation:
•
The workaround is to reduce the number of VLANs or trunks. (CSCeb31087)
Device Manager Limitations
These are the Device Manager limitations for this release:
•
The workaround is to click Yes when you are prompted to accept the certificate. (CSCef45718)
•
There is no workaround (CSCsd98457).
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, check that there is network connectivity between the switch and the ACS. You should also check that the switch has been properly configured as an AAA client on the ACS.
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 caveats for this software release.
Open Cisco IOS Caveats
This section describes the open severity 3 Cisco IOS configuration caveats with possible unexpected activity in this software release:
•
When an IEEE 802.1x restricted VLAN is configured on a port, and a hub with multiple devices is connected to that port, no syslog messages are generated.
This is not a supported configuration. Only one host should be connected to an IEEE 802.1x restricted VLAN port.
•
When the Control Plane Policing (CoPP) policy is configured to drop packets that have IP options, packets with incorrectly created IP options are ignored.
The workaround is to configure CoPP to filter IP packets by source or destination address and not use the IP option for ACL filtering with CoPP.
•
An extra index in the port table of the ciscoStpExtensions MIB does not exist in the portCrossIndex MIB. For example, extra indexes such as 1000-16/40 are seen in stpxRootGuardConfigEnabled displays that do not exist in portCrossIndex, and they appear during an SNMP walk operation.
There is no workaround.
•
When a Cisco device is configured for Network Admission Control and the EAP over UDP port number is changed from its default value and then changed back with the eou default switch configuration command, the port change does not take effect, and EAP over UDP sessions can remain in a hold state.
The workaround is to reset the EAP over UDP port number to its default value (0x5566) by using the eou port 21862 switch configuration command.
•
When you configure a Cisco IP Phone to use Network Admission Control, the CDP packet is delayed, and the phone is identified as an agentless host without an identity profile.
The workaround is to enter the eou initialize ip address switch configuration command to revalidate the host that CDP has learned.
•
MAC address notification traps do not work when you have enabled port security on the interface.
The workaround is to disable port security on the interface.
•
When IEEE 802.1x is enabled on a source port for a SPAN session, Extensible Authentication Protocol over LAN (EAPOL) packets are not visible to the packet sniffing tool.
The workaround is to enable a voice VLAN on the SPAN source port.
•
When you filter a MAC address by entering the mac-address-table static vlan drop global configuration command, IEEE 802.1X still authenticates that address.
There is no workaround.
•
When you use the CiscoConfigCopyMIB to copy a configuration to the running configuration file, the switch might fail or display illegal memory access messages during the SNMP timer process.
This might happen when rmon alarm global configuration commands are present in the running configuration before downloading the copy.
The workaround is to disable all rmon alarm global configuration commands by using the no rmon alarm global configuration command before copying the configuration.
•
Removing the bridge topology change trap with the no snmp-server enable traps bridge topology change configuration command also disables the stpx root-inconsistency trap.
The workaround is to re-enable the stpx root-inconsistency trap by using the snmp-server enable traps stpx configuration command.
•
This error message appears during authentication when a method list is used, and one of the methods in the method list is removed:
AAA-3-BADMETHODERROR:Cannot process authentication method 218959117There is no workaround. However, this is only an informational message and does not affect switch functionality.
•
When you enter the show interfaces transceiver properties privileged EXEC command, the output does not correctly show the attached SFP module type if you have set the media-type interface configuration command to rj45, or if the interface is physically linked with the RJ-45 interface. This applies to the dual-media Ethernet interfaces Gi0/17 to Gi0/20. The incorrect output only occurs when the interface is physically linked with the RJ-45 interface, and the SFP module is not in use.
When the dual-media Ethernet interface is configured for media-type rj45, the attached SFP module type displays 10/100/1000BASE-TX, even though a fiber 1000BASE-SX SFP module is installed. When the interface is configured for media-type auto-select, the attached SFP module type displays unknown, even though a fiber 1000BASE-SX SFP module is installed.
The workaround is to identify the type of SFP module that is installed when the dual-media Ethernet interface is linked with an RJ-45 interface, configure the media-type to auto-select, and enter the shutdown interface configuration command to administratively disable the interface. Then enter the show interfaces transceiver properties privileged EXEC command to see the correct output.
•
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 you globally disable IEEE 802.1x 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 you attempt to configure interface level IEEE 802.1x parameters.
•
When you remove a voice VLAN from a secure port, this message appears:
PORT_SECURITY-6-VLAN_REMOVED: VLAN xxx is no longer allowed on port ppp. Its port security configuration has been removed.
There is no workaround. This is only a notification; no action is required.
•
When you enter the no speed interface configuration command, the Ethernet interface speed does not return to its default setting. This affects interfaces Gi0/17 to Gi0/20, Gi0/23, and Gi0/24. This does not affect interfaces Gi0/21 and Gi0/22.
The workaround is either to enter the speed interface configuration command auto keyword to change the interface speed to the default setting or to explicitly set the speed.
•
If you enter the test cable-diagnostics tdr privileged EXEC command on the dual-media interfaces Gi0/23 and Gi0/24, the Ethernet interface that is being tested shuts down and then comes back up.
There is no workaround.
•
When you change the media-type interface configuration command keyword from auto to rj45, the interface loses its link and does not recover it. This only affects the dual-media Ethernet interfaces Gi0/17 to Gi0/20, Gi0/23, and Gi0/24 when the interface is physically linked with the RJ-45 interface; it does not affect interfaces Gi0/21 or Gi0/22. This occurs when you have explicitly configured the duplex interface configuration command or the the speed interface configuration command to a keyword other than auto.
The workaround is to reconfigure the Ethernet interface for media-type rj45. Set the speed and duplex to auto. Then change the media-type to auto-select. Speed and duplex configurations are not permitted if the media-type is set to auto-select.
•
These error messages appear when you enter the service-policy interface configuration command on interface fa0:
QoS: policymap is supported on physical and VLAN interfaces only Service Policy attachment failed
Remove policy failed for interface Fa0
There is no workaround. The fa0 interface does not support service policies.
•
The Ethernet interface fa0 loses and regains its link because of a DHCP IP address timeout. This situation exists when the HP Onboard Administrator acts as the DHCP server and provides the IP address to the fa0 interface. This occurs when using the clear arp-cache privileged EXEC command to explicitly clear the ARP table.
The workaround is to add a static ARP table entry for the DHCP server (in this case, the Onboard Administrator) to the switch and to increase the lease time of the DHCP IP address on the server.
Open Device Manager Caveats
This section describes the open severity 3 Device Manager caveats with possible unexpected activity in this software release:
•
On the device manager Front Panel view, port fa0 remains green even if the port is administratively shut down.
There is no workaround.
•
If you access the Device Manager by using the IP address that is assigned through the fa0 interface, and you create a management VLAN, the Management VLAN field in the Device Manager window appears to be editable even though it has already been created.
The workaround is to refresh the Device Manager window by choosing Configure > Express Setup or by clicking Refresh in the device manager toolbar.
•
When any of the dual-purpose ports Gi0/17 to Gi0/20 are configured as an RJ-45 port, the Device Manager front panel incorrectly shows the SFP module slots Gi0/17 to Gi0/20 as having a 1000BASE-TX module.
There is no workaround.
Resolved Caveats
This sections describes the caveats that have been resolved in these releases:
•
•
Resolved Caveats in Cisco IOS Release 12.2(25)SEF1 and Later
This section describes the caveats that have been resolved in Cisco IOS Release 12.2(25)SEF1 and later.
•
Multiple Cisco products contain either of two authentication vulnerabilities in the Simple Network Management Protocol version 3 (SNMPv3) feature. 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.
The United States Computer Emergency Response Team (US-CERT) has assigned Vulnerability Note VU#878044 to these vulnerabilities.
Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-0960 has been assigned to these vulnerabilities.
This advisory will be posted at http://www.cisco.com/warp/public/707/cisco-sa-20080610-snmpv3.shtml
•
Date changes in Daylight Savings Time in 2007 might no longer cause Cisco IOS to generate timestamps, such as in syslog messages, that are inaccurate by 1 hour.
Resolved Caveats in Cisco IOS Release 12.2(25)SEF1
This section describes the caveats that have been resolved in Cisco IOS Release 12.2(25)SEF1.
•
Symptoms: A router may crash if it receives a packet with a specific crafted IP option as detailed in Cisco Security Advisory: Crafted IP Option Vulnerability:
http://www.cisco.com/warp/public/707/cisco-sa-20070124-crafted-ip-option.shtml
Conditions: This DDTS resolves a symptom of CSCec71950. Cisco IOS with this specific DDTS are not at risk of crash if CSCec71950 has been resolved in the software.
Workaround: Cisco IOS versions with the fix for CSCec71950 are not at risk for this issue and no workaround is required. If CSCec71950 is not resolved, see the following Cisco Security Advisory: Crafted IP Option Vulnerability for workaround information:
http://www.cisco.com/warp/public/707/cisco-sa-20070124-crafted-ip-option.shtml
•
The Cisco IOS Transmission Control Protocol (TCP) listener in certain versions of Cisco IOS software is vulnerable to a remotely-exploitable memory leak that may lead to a denial of service condition.
This vulnerability only applies to traffic destined to the Cisco IOS device. Traffic transiting the Cisco IOS device will not trigger this vulnerability.
Cisco has made free software available to address this vulnerability for affected customers.
This issue is documented as Cisco bug ID CSCek37177.
There are workarounds available to mitigate the effects of the vulnerability.
This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20070124-crafted-tcp.shtml
•
When a Cisco IP Phone is connected to a switch, only the voice VLAN (VVID) of the switch learns the MAC address of phone. This is the correct behavior.
In previous releases, the MAC address was learned on both the VVID and the Data VLAN (PVID). When the dynamic MAC addresses were removed (manually or automatically) either by a topology change or by enabling or disabling the port security or the IEEE 802.1x feature, the MAC address of Cisco IP Phones MAC address was relearned only on the VVID.
•
It is no longer necessary to detach and then reapply a hierarchical policy map to force changes to a VLAN level class-map to take effect.
•
A switch no longer fails IEEE 802.1x authentication if it downloads an access control list (ACL) that has more than 20 ACL access control entries (ACEs) from a RADIUS server.
•
The switch can now forward an IEEE802.1x request that has null credentials.
•
When the radius-server source-ports 1645-1646 global configuration command is removed, the switch no longer sends the RADIUS server requests with incorrect source ports, which caused failed authentication attempts.
•
If you globally disable IEEE 802.1x authentication by using the no dot1x system-auth-control global configuration command and if the dot1x port-control auto or the dot1x port-control force-unauthorized interface configuration command was previously entered, the dot1x port-control auto or the dot1x port-control force-unauthorized interface configuration command no longer takes effect, and the host can now access the port.
•
SFP interfaces now reliably connect to a Cisco Catalyst 6500 series switch.

In addition, if you have a valid Cisco service contract, Cisco Technical Assistance Center (TAC) engineers provide telephone support. If you do not have a valid Cisco service contract, contact your reseller.

Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411
Australia: 1 800 805 227
EMEA: +32 2 704 55 55
USA: 1 800 553 2447For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is "down" or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
