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
If you wish to use Device Manager to upgrade the switch from Cisco IOS Release 12.2(35)SE through Cisco IOS Release 12.2(40)SE1 (the LAN Base image) to Cisco IOS Release 12.2(44)SE or later (the IP base image), you must first upgrade to Cisco IOS Release 12.2(40)SE2.
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/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
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 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
When using the device manager to upgrade your switch, do not use or close your browser session after the upgrade process begins. Wait until after the upgrade process completes.
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
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/public/sw-center/sw-lan.shtml
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 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-addressFor more information about assigning an IP address and default gateway to the switch, see the software configuration guide for this release.
Step 6
Download the image file from the TFTP server to the switch. If you are installing the same version of software that is currently on the switch, overwrite the current image by entering this privileged EXEC command:
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.
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 by using these methods:
•
The Express Setup program or the HP Onboard Administrator program described in the getting started guide.
•
The CLI-based setup program, as described in the hardware installation guide.
•
The DHCP-based autoconfiguration, as described in the software configuration guide.
•
Manually assigning an IP address, as described in the software configuration guide.
New Software Features
These are the new software features for this release:
•
DHCP-based autoconfiguration and image update to download a specified configuration and image to a large number of switches
•
Configurable small-frame arrival threshold to prevent storm control when small frames (64 bytes or less) arrive on an interface at a specified rate (the threshold)
•
Support for the *, ip-address, interface interface-id, and vlan vlan-id keywords with the clear ip dhcp snooping command
•
HTTP and HTTP(s) support over IPv6, which eliminates the need to run dual stack on the switch
•
Simple Network and Management Protocol (SNMP) can be configured over IPv6 transport so that an IPv6 host can send SNMP queries and receive SNMP notifications from a device running IPv6
•
IPv6 supports stateless autoconfiguration to manage link, subnet, and site addressing changes, such as management of host and mobile IP addresses
•
IEEE 802.1x readiness check to determine the readiness of connected end hosts before configuring IEEE 802.1x on the switch
•
The switch now ships with the IP base image installed, which provides Layer 2+ features, including static routing, EIGRP and PIM stub routing, the Hot Standby Router Protocol (HSRP), the Routing Information Protocol (RIP), IPv6 host management, and IPv6 MLD snooping
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" section
•
"Device Manager Limitations" section
Cisco IOS Limitations
These limitations apply to the switch:
•
"MAC Addressing Multicasting" section
Configuration
•
A static IP address might be removed when the previously acquired DHCP IP address lease expires.
This problem occurs under these conditions:
–
When the switch is booted without a configuration (no config.text file in flash memory).
–
When the switch is connected to a DHCP server that is configured to give an address to it (the dynamic IP address is assigned to VLAN 1).
–
When an IP address is configured on VLAN 1 before the dynamic address lease assigned to VLAN 1 expires.
The workaround is to reconfigure the static IP address. (CSCea71176 and CSCdz11708)
•
When connected to some third-party devices that send early preambles, a switch port operating at 100 Mp/s full duplex or 100 Mp/s half duplex might bounce the line protocol up and down. The problem is observed only when the switch is receiving frames.
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)
•
When port security is enabled on an interface in restricted mode and the switchport block unicast interface command has been entered on that interface, MAC addresses are incorrectly forwarded when they should be blocked
The workaround is to enter the no switchport block unicast interface configuration command on that specific interface. (CSCee93822)
•
A traceback error occurs if a crypto key is generated after an SSL client session.
There is no workaround. This is a cosmetic error and does not affect the functionality of the switch. (CSCef59331)
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 random source-ip and dest-ip traffic, configure load balance method as src-dst-ip
•
for incrementing source-ip traffic, configure load balance method as src-ip
•
for incrementing dest-ip traffic, configure load balance method as dst-ip
•
Configure the number of ports in the EtherChannel so that the number is equal to a power of 2 (for example, 2, 4, or 8)
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. (CSCea85312)
MAC Addressing Multicasting
•
If the number of multicast routes and Internet Group Management Protocol (IGMP) groups are more than the maximum number specified by the show sdm prefer global configuration command, the traffic received on unknown groups is flooded in the received VLAN even though the show ip igmp snooping multicast-table privileged EXEC command output shows otherwise. The workaround is to reduce the number of multicast routes and IGMP snooping groups to less than the maximum supported value. (CSCdy09008)
•
IGMP filtering is applied to packets that are forwarded through hardware. It is not applied to packets that are forwarded through software. Hence, with multicast routing enabled, the first few packets are sent from a port even when IGMP filtering is set to deny those groups on that port. There is no workaround. (CSCdy82818)
•
If an IGMP report packet has two multicast group records, the switch removes or adds interfaces depending on the order of the records in the packet:
–
If the ALLOW_NEW_SOURCE record is before the BLOCK_OLD_SOURCE record, the switch removes the port from the group.
–
If the BLOCK_OLD_SOURCE record is before the ALLOW_NEW_SOURCE record, the switch adds the port to the group.
There is no workaround. (CSCec20128)
•
When IGMP snooping is disabled and you enter the switchport block multicast interface configuration command, IP multicast traffic is not blocked.
The switchport block multicast interface configuration command is only applicable to non-IP multicast traffic.
There is no workaround. (CSCee16865)
•
Incomplete multicast traffic can be seen under either of these conditions:
–
You disable IP multicast routing or re-enable it globally on an interface.
–
A switch mroute table temporarily runs out of resources and recovers later.
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:
–
Cancel membership in the multicast group by using the no ip igmp join-group group-address interface configuration command on an SVI.
–
Disable IGMP snooping on the VLAN interface by using the no ip igmp snooping vlan vlan-id global configuration command. (CSCeh90425)
QoS
•
Some switch queues are disabled if the buffer size or threshold level is set too low with the mls qos queue-set output global configuration command. The ratio of buffer size to threshold level should be greater than 10 to avoid disabling the queue. The workaround is to choose compatible buffer sizes and threshold levels. (CSCea76893)
•
When auto-QoS is enabled on the switch, priority queuing is not enabled. Instead, the switch uses shaped round robin (SRR) as the queuing mechanism. The auto-QoS feature is designed on each platform based on the feature set and hardware limitations, and the queuing mechanism supported on each platform might be different. There is no workaround. (CSCee22591)
•
A QoS service policy with a policy map containing more than 62 policers cannot be added to an interface by using the service-policy interface configuration command.
The workaround is to use policy maps with 62 or fewer policers. (CSCsc59418)
SPAN and RSPAN
•
Egress SPAN routed packets (both unicast and multicast) show the incorrect source MAC address. For remote SPAN packets, the source MAC address should be the MAC address of the egress VLAN, but instead the packet shows the MAC address of the RSPAN VLAN. For local SPAN packets with native encapsulation on the destination port, the packet shows the MAC address of VLAN 1. This problem does not appear with local SPAN when the encapsulation replicate option is used. This limitation does not apply to bridged packets. The workaround is to use the encapsulate replicate keywords in the monitor session global configuration command. Otherwise, there is no workaround. This is a hardware limitation. (CSCdy81521)
•
During periods of very high traffic when two RSPAN source sessions are configured, the VLAN ID of packets in one RSPAN session might overwrite the VLAN ID of the other RSPAN session. If this occurs, packets intended for one RSPAN VLAN are incorrectly sent to the other RSPAN VLAN. This problem does not affect RSPAN destination sessions. The workaround is to configure only one RSPAN source session. This is a hardware limitation. (CSCea72326)
•
Cisco Discovery Protocol (CDP), VLAN Trunking Protocol (VTP), and Port Aggregation Protocol (PAgP) packets received from a SPAN source are not sent to the destination interfaces of a local SPAN session. The workaround is to use the monitor session session_number destination {interface interface-id encapsulation replicate} global configuration command for local SPAN. (CSCed24036)
Trunking
•
The switch treats frames received with mixed encapsulation (IEEE 802.1Q and Inter-Switch Link [ISL]) as frames with FCS errors, increments the error counters, and the port LED blinks amber. This happens when an ISL-unaware device receives an ISL-encapsulated packet and forwards the frame to an IEEE 802.1Q trunk interface. There is no workaround. (CSCdz33708)
•
IP traffic with IP options set is sometimes leaked on a trunk port. For example, a trunk port is a member of an IP multicast group in VLAN X but is not a member in VLAN Y. If VLAN Y is the output interface for the multicast route entry assigned to the multicast group and an interface in VLAN Y belongs to the same multicast group, the IP-option traffic received on an input VLAN interface other than one in VLAN Y is sent on the trunk port in VLAN Y because the trunk port is forwarding in VLAN Y, even though the port has no group membership in VLAN Y. There is no workaround. (CSCdz42909).
•
For trunk ports or access ports configured with IEEE 802.1Q tagging, inconsistent statistics might appear in the show interfaces counters privileged EXEC command output. Valid IEEE 802.1Q frames of 64 to 66 bytes are correctly forwarded even though the port LED blinks amber, and the frames are not counted on the interface statistics. There is no workaround. (CSCec35100).
VLAN
•
If the number of VLANs times the number of trunk ports exceeds the recommended limit of 13,000, the switch can fail.
The workaround is to reduce the number of VLANs or trunks. (CSCeb31087)
Device Manager Limitations
•
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)
•
When the physical UID LED of the switch is on, it is blue. However, when the image of this LED on the device manager Front Panel view is on, it is green.
There is no workaround (CSCsd98457).
Important Notes
These sections describe the important notes related to this software release:
•
"Device Manager Notes" section
Cisco IOS Notes
These notes apply to Cisco IOS software:
•
The behavior of the no logging on global configuration command changed in Cisco IOS Release 12.2(18)SE and later. You can only use the logging on and then the no logging console global configuration commands to disable logging to the console. (CSCec71490)
•
In Cisco IOS Release 12.2(25)SEC, the implementation for multiple spanning tree (MST) changed from the previous release. Multiple STP (MSTP) complies with the IEEE 802.1s standard. Previous MSTP implementations were based on a draft of the IEEE 802.1s standard.
•
If the switch 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 and the ACS. You should also make sure that the switch has been properly configured as an AAA client on the ACS.
•
Cisco IOS Release 12.2(40)SE and later
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:
•
We recommend this browser setting to more quickly 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. 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 the HTTP protocol (the default is port 80) and the default method of authentication (the enable password) to communicate with the switch through any of its Ethernet ports and to allow switch 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 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:
•
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 start the device manager.
Open Caveats
•
This section describes the open severity 3 Cisco IOS configuration caveats with possible unexpected activity in this software release:CSCsc96474
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

There is no workaround.
•
CSCsd03580
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.
•
CSCsj74022
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.
•
CSCsk65142
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.

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.

CSCsx42798
A switch no longer displays processor memory-allocation failure messages under these conditions:
–
The switch is running IOS release 12.2(44)SE4 or 12.2(44)SE5.
–
Authentication, authorization, and accounting (AAA) is configured on the switch.
–
Memory in the primary processor pool is depleted.
Note
If the hardware configuration is not a switch stack, AAA requests might fail and the switch might experience high CPU usage for the authentication manager process. In addition, if the hardware configuration is a switch stack and 802.1x, web authentication, or MAC address bypass (MAB) are configured, the switch software might reload after reporting the memory-allocation failure.
This is resolved in Cisco IOS 12.2(44)SE6 and later.

Documentation Updates
This section contains these documentation updates:
•
"Updates to the Software Configuration Guide" section
•
"Updates to the System Message Guide" section
Updates to the Software Configuration Guide
These are the updates to the software configuration guide:
•
This information in the "Enabling BPDU Guard" section of the "Configuring Optional Spanning-Tree Features" chapter in the software configuration guide is incorrect:
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.
•
When routing is enabled on the switch, you can configure complete EIGRP routing. However, the configuration is not implemented because the software supports only EIGRP stub routing, as described in the "Configuring IP Unicast Routing" chapter of the software configuration guide.
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.
