Note
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. 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.
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. To upgrade the switch through the command-line interface (CLI), use the tar file and the archive download-sw privileged EXEC command.
Table 2 lists the software filename for this software release.
Table 2 Cisco IOS Software Image Files for Catalyst 3750 Metro Switches
Filename
c3750me-i5-tar.122-52.SE.tar
Cisco IOS image tar file.
This image has Layer 2+ and Layer 3 features.c3750me-i5k91-tar.122-52.SE.tar
Cisco IOS cryptographic image tar file.
This image has the Kerberos, SSH1 , SSL2 , Layer 2+, and Layer 3 features.
1 SSH = Secure Shell
2 SSL = Secure Socket Layer
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 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 CLI
This procedure is for copying the 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.
Download the software from Cisco.com to your management station by following these steps:
Step 1
Step 2
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 files, click the link for your switch platform, and then follow the links on the page to select the correct tar image file.
Step 3
For more information, see Appendix B in the software configuration guide for this release.
Step 4
Step 5
Step 6
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 been 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/c3750me-i5-tar.122-50.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
Switch software can be corrupted during an upgrade, by downloading the wrong file to the switch, and by deleting the image file. In all of these cases, the switch does not pass the power-on self-test (POST), and there is no connectivity. You can use the Xmodem protocol to recover from these failures.
For detailed 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.
•
•
•
•
•
•
Configuration
•
This problem occurs under these conditions:
–
–
–
The workaround is to reconfigure the static IP address. (CSCea71176)
•
The workaround is to upgrade to Cisco IOS Release 12.2(25)EY or later. (CSCec35100)
•
These are the workarounds:
1.
2.
3.
•
–
–
–
No workaround is necessary; these are the designed behaviors. (CSCed50819)
•
However, when dynamic ARP inspection is not enabled and jumbo MTU is configured, ARP and RARP packets are correctly bridged in hardware. (CSCed79734)
•
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)
•
When you enter the show ip arp inspection log privileged EXEC command, the log entries from all switches in the stack are moved to the switch on which the command was entered.
There is no workaround. (CSCed95822)
•
The workaround is to enter the no switchport block unicast interface configuration command for that specific interface. (CSCee93822)
•
The workaround is to statically configure the MAC address of port 1/0/3 in the CAM table of the switch bound to port 1/0/2 by using the mac address-table static mac-addr vlan vlan-id interface fastethernet1/0/2 global configuration command. (CSCee87864)
•
There is no workaround. This is a cosmetic error and does not affect the functionality of the switch. (CSCef59331)
•
2d20h: %PLATFORM_UCAST-3-LB: PI<->PD handles out of sync for Adj 222.1.1.1 LB -Traceback= 252620 A919CC A847E0 A85BE0 A927FC AA2D28 A965E0 A89C08 A78744 B08F48 ADF504 ADDC4C AE3460 AD25CC B94AA0 B94F20
There is no workaround. (CSCeh13477)
•
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. (CSCsk65142)
EtherChannel
•
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 879A58There is no workaround.(CSCsh12472)
Fallback Bridging
•
The workaround is to remove the VLAN from the bridge group or to remove the static MAC address from the VLAN. (CSCdw81955)
•
The workaround is to disable fallback bridging. To remove an interface from a bridge group and to remove the bridge group, use the no bridge-group bridge-group interface configuration command. Another workaround is to disable port security on all ports in all VLANs participating in fallback bridging by using the no switchport port-security interface configuration command. (CSCdz80499)
Hot Standby Routing Protocol (HSRP)
•
The workaround is to ensure that the ports on the standby cluster members are not in the spanning-tree blocking state. To verify that these ports are not in the blocking state, see the "Configuring STP" chapter in the software configuration guide. (CSCec76893)
•
There is no workaround. Do not configure HSRP on MPLS interfaces. (CSCeg76540)
IP
•
The workaround is to set an ARP timeout value higher than 120 seconds. (CSCea21674)
•
The workaround is to use rate limiting on DHCP traffic to prevent a denial of service attack from occurring. (CSCeb59166)
IP Telephony
•
The workaround is to power the AP by using an AC wall adaptor. (CSCin69533)
•
There is no workaround. (CSCea85312)
logging event-spanning-tree Command
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 utilization. CPU utilization 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 operates and could cause problems such as STP convergence delay.
High CPU utilization 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:
•
•
•
•
The workaround is to configure aggressive UDLD. (CSCsh70244).
MAC Addressing
When a MAC address is configured for filtering on the internal VLAN of a routed port, incoming packets from the MAC address to the routed port are not dropped. (CSCeb67937)
Multiprotocol Label Switching (MPLS) and Ethernet over MPLS (EoMPLS)
•
The workaround is to configure the incoming ports as an IEEE 802.1Q trunk or as an access port. (CSCeb44014)
•
The workaround is to use the show mpls ldp parameter user EXEC command to see the configured value. (CSCeb76775)
•
There is no workaround. (CSCec13655)
•
The workaround is to allow the EoMPLS VLAN on the trunk on the ES ports. (CSCsc42814)
•
When you mark SNMP packets to an IP DSCP value setting, and you then mark the control plane protocol packets to a different CPU traffic quality of service (QoS) value setting, the CPU traffic setting overrides the SNMP IP DSCP setting.
This only occurs on the enhanced services ports with Multiprotocol Label Switching (MPLS) configured. The FastEthernet and Gigabit Ethernet customer edge ports are not affected.
There is no workaround. You can specify the marking as either SNMP IP DSCP or as CPU traffic QoS, not both.
•
There is no workaround. (CSCsq24540)
Multicasting
•
•
There is no workaround because non-RPF traffic is continuous in certain topologies. As long as the trunk port is a member on a trunk port in at least one VLAN, this problem for the non-RPF traffic occurs. (CSCdu25219)
•
The workaround is to reduce the number of multicast routes and IGMP snooping groups to less than the maximum supported value. (CSCdy09008)
•
There is no workaround. (CSCdy82818)
•
The workaround is to not apply a router ACL configured to deny access to a VLAN interface. Apply the security through other means; for example, apply VLAN maps to the VLAN instead of using a router ACL for the group. (CSCdz86110)
•
Multicast is not supported on tunnel interfaceserror message. IP PIM is not supported on tunnel interfaces.There is no workaround. (CSCeb75366)
•
–
–
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 clear ip mroute privileged EXEC command on the interface. (CSCef42436)
•
There is no workaround. (CSCef67261)
•
–
–
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)
Quality of Service (QoS)
•
•
The workaround is to choose compatible buffer sizes and threshold levels. (CSCea76893)
•
There is no workaround. (CSCeb75230)
•
There is no workaround. (CSCeb80223)
•
There is no workaround. (CSCeb80300)
•
There is no workaround. (CSCec08205)
•
The workaround is to configure explicit matches for traffic that requires priority treatment. (CSCec38901)
•
The workaround is to detach the service policy from the port while making the modifications and then to re-attach the service policy. (CSCec75945)
•
If this becomes a problem, you can change switch behavior by using the queue-limit policy-map class configuration command at the class level to set shorter queue depths. Each shaper has an associated buffer queue with a default depth of 128 packets.
For example:
Switch(config)# policy-map cos2-policySwitch(config-pmap)# class cos2Switch(config-pmap-c)# bandwidth 50000Switch(config-pmap-c)# queue-limit 32The point at which buffer memory is exhausted depends on the number of queues, the sizes of the queued packets, and whether or not the traffic pattern being sent to the switch allows the queues to drain at all.
Upgrading your switch to Cisco IOS Release 12.2(25)EY or later greatly reduces the possibility of this situation happening, although it can still occur with some configurations and traffic patterns. (CSCed83886)
•
There is no workaround. (CSCee22591)
•
The workaround is to use the CLI to enable the trap by entering the snmp-server enable traps mpls fast-reroute [protected] global configuration command. (CSCsq07065)
Resilient Ethernet Protocol (REP)
•
There is no workaround. (CSCsk00716)
•
–
–
–
–
–
You cannot enable these functions on REP segments without edge ports.
•
The workaround is to use the rep lsl-age-out timer interface configuration command to configure the REP LSL age timer for more than 1000 milliseconds (1 second). (CSCsz40613)
Routing
•
•
There is no workaround. (CSCea52915)
•
–
–
–
The workaround is to change any one of the listed conditions. (CSCed53633)
•
There is no workaround. (CSCsj41522)
SPAN and Remote SPAN (RSPAN)
•
There is no workaround for a remote SPAN session. This is a hardware limitation. (CSCdy72835)
•
The workaround is to use the encapsulate replicate keywords in the monitor session global configuration command. This is a hardware limitation. (CSCdy81521)
•
The workaround is to configure only one RSPAN source session. (CSCea72326)
•
Decreased egress SPAN rate.In all cases, normal traffic is not affected; the degradation limits only how much of the original source stream can be monitored. If fallback bridging and multicast routing are disabled, egress-SPAN monitoring is not degraded.
There is no workaround. If possible, disable fallback bridging and multicast routing. If possible, use ingress-SPAN to observe the same traffic. (CSCeb01216)
•
There is no workaround. (CSCeb23352)
•
The workaround is to use the monitor session session_number destination {interface interface-id encapsulation replicate} global configuration command for a local SPAN session. (CSCed24036)
•
There is no workaround. (CSCsj21718)
Trunking
•
There is no workaround. (CSCdz33708)
•
There is no workaround. (CSCdz42909)
•
There is no workaround. (CSCec35100).
•
3d20h: %PLATFORM_UCAST-3-LB: PI<->PD handles out of sync for Adj 222.1.1.1 LB -Traceback= 252620 A9204C A84E60 A86260 A92E7C AA36A0 AA3520 A96C60 A8A288 A78DC4 B095C8
There is no workaround. This does not affect switch functionality. (CSCeh20081)
Tunneling
•
The workaround is to configure identical VLAN mappings on both ES ports if they are going to be bundled into an EtherChannel. (CSCec49520)
VLAN
•
The workaround is to reduce the number of VLANs or trunks. (CSCeb31087)
•
There is no workaround. (CSCed71422)
•
The workaround is to define another policy-map name for the second-level policy-map with the same configuration to be used for another policy-map. (CSCef47377)
Important Notes
•
By definition, the local PE H-VPLS VLAN should not be relevant for the VPLS network. Because the local PE SVI with the xconnect and the remote PE SVI with the xconnect do not need to be on the same VLAN, it does not matter if the VLAN is carried across the transport network or not. However, problems could occur if a service provider deployed the Catalyst 3750M switch using the H-VPLS VLAN as the customer VLAN when H-VPLS came up with VC type 5 because the customer VLAN tag would not be consistent across the transport. The new behavior is now consistent with the Cisco default.
•
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.
•
–
–
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)
•
•
Note
•
Note
Open Caveats
•
When a class-map entry is added or modified, a delay of several seconds can occur if the switch already has many policy maps defined. For example, a 6- second delay occurs when a new class map is added to the a switch that already has 400 hierarchical QoS policies defined.
The delay occurs even if the policy maps are not attached to a switch interface. The console might also be unresponsive when this occurs.
There is no workaround.
•
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.
•
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:
–
–
Resolved Caveats
This release resolves these previously open caveats:
•
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.
•
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.
The workaround, if the groups are not displaying correctly, is to create the MVR VLAN before enabling MVR. The configuration then displays correctly.
•
When a switch sends an ARP request to find the MAC address of the default gateway, the switch sends the request in the wrong VLAN. An ARP entry associating the MAC address with the wrong VLAN is added to the table.
The workaround is to use the no arp arpa global configuration command in all VLANs with IDs lower than the ID of the correct VLAN.
•
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.
•
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:
–
–
•
If a switch is directly connected to another switch and both are running Cisco IOS IP Service Level Agreements (SLAs) to monitor jitter, a message about high jitter appears and then the problem is resolved automatically when the event does not occur:
036814: Feb 11 23:30:04: IP SLAs (10) jitter operation: seq=12, jitterIn=44036820: Feb 11 23:30:05: IP SLAs (10) jitter operation: seq=13, jitterIn=-44There is no workaround.
•
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.
•
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:
–
–
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.
•
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:
–
–
•
On an enhanced services (ES) port where you have configured bandwidth by entering the bandwidth value policy configuration command for a hierarchical policy, when a traffic stream bandwidth reservation is for a low rate (that is, less than 100 kb/s), the reservation is honored. However, the stream can become very bursty under congestion, especially when other streams at the same level of the QoS hierarchy are reserving substantially more bandwidth.
There is no workaround.
•
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.
•
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.
•
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.
•
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.
•
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.
Documentation Updates
The clustering chapter has been removed from the software configuration guide and the commands removed from the command reference. The Catalyst 3750 Metro switch does not support clustering.
This section contains these documentation updates:
•
•
•
Updates to the Software Configuration Guide
Updates to the "Configuring Ethernet OAM, CFM, and E-LMI" Chapter
•
The Service Diagnostics 2.0 C FM diagnostic scripts is part of the 12.2(52)SE release. The script is available for download at:
Refer to the Service Diagnostic 2.0 user guide at:
http://www.cisco.com/en/US/prod/collateral/iosswrel/ps6537/ps6555/ps9424/whitepaper_c11-566741.html
•
In the "Configuring the CFM Domain" section, Step 2 was to enter the ethernet cfm ieee global configuration command to configure the CFM version as IEEE 802.1ag.
This step is not required. If you are running Cisco IOS Release 12.2(52)SE, the CFM version is always 802.1ag and the command is automatically generated when you enable CFM.
Update to the "Configuring IEEE 802.1x Port-Based Authentication" Chapter
This section was added:
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:

Installation Update
Cisco Ethernet Switches are equipped with cooling mechanisms, such as fans and blowers. However, these fans and blowers can draw dust and other particles, causing contaminant buildup inside the chassis, which can result in a system malfunction.
You must install this equipment in an environment as free as possible from dust and foreign conductive material (such as metal flakes from construction activities).
These standard provide guidelines for acceptable working environments and acceptable levels of suspended particulate matter:
