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 4 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/partner/products/sw/iosswrel/ps5187/prod_bulletin0900aecd80281c0e.
HtmlYou can copy the binary software image file (with the .bin suffix) 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.122-46.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.
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 the 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 Mp/s and half duplex or to connect a hub or a nonaffected device to the switch. (CSCed39091)
•
–
–
No workaround is necessary. (CSCed50819)
•
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:
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
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
This is the IP telephony limitation:
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. (CSCea85312)
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)
–
•
–
–
When multicast traffic is sent in one direction and unicast traffic is sent in another, unicast traffic is dropped at the multicast traffic source port.
The workaround is to apply a policy map so that the least significant traffic is discarded. (CSCsq83882)
QoS
These are the quality of service (QoS) limitations:
•
•
•
The workaround is to use policy maps with 62 or fewer policers. (CSCsc59418)
SPAN and RSPAN
These are the SPAN and Remote SPAN (RSPAN) limitations:
•
•
•
Trunking
These are the trunking limitations:
•
•
•
VLAN
These are the VLAN limitations:
•
The workaround is to reduce the number of VLANs or trunks. (CSCeb31087)
•
Device Manager Limitations
This is the device manager limitation for this release:
•
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.
•
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:
•
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.
•
When you use the ipv6 address dhcp interface configuration command on an interface that is configured in router mode, other addresses on the prefix associated with the new address might not be accessible.
The workaround is to use the ipv6 address dhcp interface configuration command on an interface that is configured in host mode, or configure a static route to the prefix through the interface.
Resolved Caveats
This section describes the caveats that have been resolved in this release:
•
These traceback messages such as these no longer appear when a large number of IEEE 802.1x supplicants repeatedly try to log in and log out.
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 Fa9Jan 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•
When IEEE 802.1x is globally disabled on the switch by using the no dot1x system-auth-control global configuration command, interface level IEEE 802.1x configuration commands, including the dot1x timeout and dot1x mac-auth-bypass commands, are now available.
•
The configuration file used for the configuration replacement feature no longer requires the character string end\n at the end of the file.
•
The switch now correctly updates the entPhysicalChildIndex objects from the ENTITY-MIB, and all of the entPhysicalChildIndex entries appear in the table.
•
When the ip pim sparse-mode and ip wccp web-cache redirect in configuration commands are applied on a global table interface, traffic is now sent to multicast receivers.
•
An end host no longer remains in the guest VLAN after IEEE 802.1X authentication.
•
When IEEE 802.1x is enabled on the switch, EAP notification packets are no longer dropped.
•
A switch no longer fails under these conditions:
–
–
•
A switch running the IP base image now supports full EIGRP stub routing.
•
The SSH Protocol now supports generic message authentication and is compliant with RFC 4256.
•
If you specify the router ID before entering the autonomous-system autonomous-system-number address-family configuration command, the router ID is no longer lost when the switch reloads.
•
Any form of the passive-interface command entered in one instance propagates to all configured address-family instances for the same EIGRP routing process.
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 sections contains these updates to the system message guide:
New System Messages
