Software Compatibility
For information about the recommended platforms for web-based management, operating systems, and browser support, refer to the "Getting Started with CMS" chapter of the software configuration guide.
Windows
This release uses a CMS plug-in (Windows only) that replaces the Java plug-in. You can download the plug-in from this URL:
http://www.cisco.com/pcgi-bin/tablebuild.pl/CMS-Plug-In-Win-1-0:
Note
Solaris
Java plug-in 1.4.1_02 is required to run CMS. You can download the Java plug-in and installation instructions from this URL:
http://www.cisco.com/public/sw-center/lan/java/1.4.1-02.htmlCluster Compatibility
This section describes how to choose command and standby command switches when a cluster consists of a mixture of Catalyst switches. The command switch must be the same type as the standby command switch.
When you create a switch cluster, we recommend configuring the highest-end switch in your cluster as the command switch. If your cluster has Catalyst 2970, Catalyst 3550, Catalyst 2950, Catalyst 2900 XL, and Catalyst 3500 XL switches, the Catalyst 3550 switch (with the latest software release) should be the command switch.
Table 2 lists the cluster capabilities and software versions for the switches. The switches are listed from the highest to lowest end. A lower-end switch cannot be the command switch of a switch listed above it in the table. For example, a Catalyst 2950 switch cannot be the command switch of a cluster that has Catalyst 2970 or Catalyst 3550 switches.

1 Catalyst 2900 XL (4-MB) switches appear in the front-panel and topology views of the Cluster Management Suite (CMS). However, CMS does not support configuration or monitoring of these switches.
Some versions of the Catalyst 2900 XL software do not support clustering, and if you have a cluster with switches that are running different versions of Cisco IOS software, software features added in the latest release might not be reflected on switches running the older versions. For example, if you start CMS on a Catalyst 2900 XL switch running Cisco IOS Release 11.2(8)SA6, the windows and functionality can be different from a switch running Cisco IOS Release 12.0(5)WC(1) or later.

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 number. 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.
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 both the Cisco IOS image file and the files needed for the CMS. You must use the combined .tar file to upgrade the switch through the CMS. 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 software filenames for this software release.
Upgrading a Switch by Using CMS
You can upgrade switch software by using CMS. From the feature bar, select Administration > Software Upgrade. For detailed instructions, click Help.
Upgrading a Switch by Using the CLI
This procedure is for copying the combined .tar file to the Catalyst 2970 switch by using the CLI. 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, and if necessary, the TFTP server application, follow these steps:
Step 1
Step 2
•
http://www.cisco.com/kobayashi/sw-center/sw-lan.shtml
•
http://www.cisco.com/public/sw-center/sw-lan.shtml
To download the image, select Catalyst 2970 software.
To obtain authorization and to download the crypto software files, select Catalyst 2970 3DES Cryptographic Software.
Step 3
For more information, refer to 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, refer to the software configuration guide for this release.
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 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/c2970-i612-tar.121-14.EA1.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 detailed recovery procedures, refer to the "Troubleshooting" chapter in the software configuration guide for this release.

In the Front Panel view, if the switch is running one of the previously listed software releases, the device LEDs do not appear. In the Topology view, if the member is a Long-Reach Ethernet (LRE) switch, the customer premises equipment (CPE) connected to the switch does not appear. The Bandwidth and Link graphs also do not appear in these views.
To view switch information, you need to upgrade the member switch software. For information about upgrading switch software, see the "Downloading Software" section.
Open Caveats
These sections describe the open caveats with possible unexpected activity in this software release:
•
Open Cisco IOS Caveats
These are the severity 3 Cisco IOS configuration caveats:
•
When multicast VLAN registration (MVR) groups are added or deleted, the receiver port that joined the groups after the addition still receives traffic even after the group is deleted. The correct behavior is that MVR data traffic to the group should stop flowing to the receiver port immediately after the no mvr group ip-address global configuration command is entered.
The workaround is to disable MVR by using the no mvr global configuration command and then to re-enable it by using the mvr command. Add and delete the groups that have problems by using the mvr group ip-address and the no mvr group ip-address global configuration commands.
•
On a voice VLAN port with both 802.1X and port security enabled, dynamic secure addresses might not be deleted when the port is changed from multihost mode to single-host mode. This means that addresses learned in the multihost mode are still allowed after changing to single-host mode. This problem occurs under these conditions:
–
–
–
The workaround is to disable and then re-enable port security on the port.
There is no workaround.
•
Although it is visible in the command-line help string, the source-only-learning keyword is not supported on the Catalyst 2970 switches. Also, the igmp snooping report-suppression feature does not work.
There is no workaround.
•
When DHCP snooping is enabled, if the lease time given by the server to the client is infinite, tracebacks are generated.
•
When both the sharing and shaping weights are enabled on Catalyst 2970 switches, the receiving rates might not follow the shared bandwidth weight if the priority queue is enabled on the egress queue.
The workaround is to use lower values of the shaped and shared weights for queues other than the first queue when the egress priority queue is enabled if shaping in other queues is required.
•
For an interface, if the voice VLAN and the access VLAN are assigned to different VLANs and the access VLAN enters a suspended state, the IP phones do not work.
The workaround is to reset the access VLAN to the active state.
•
When an ACL that denies packets is configured on an ingress or an egress interface, the CPU usage might be as high as 70% because these packets are forwarded to the CPU to determine if an ICMP-unreachable packet should be generated.
There is no workaround.
•
When a 802.1X enabled port is authenticated with a radius-assigned VLAN, the port is shut down or link is removed, and a traceback message appears.
There is no workaround.
•
After a link is up, a switch sends three EAP-Request/Identity messages to the client. There is a 30-second gap between messages. However, PCs that are running Windows XP or Windows 2000 drop the first message so that the second message that the client receives appears to be the first, which is at least 30 seconds after the link is up. Therefore, a user does not see a password window until at least 30 seconds after the link is up.
There is no workaround.
•
If per-user access control lists (ACLs) are downloaded from a RADIUS server after successful 802.1X authentication, disabling 802.1X does not remove the attached per-user ACLS from the interface.
The workaround is to enter the shutdown and no shutdown interface configuration commands to remove the ACLs.
•
If you change the input priority queue for queue 2 by using the mls qos srr-queue input priority-queue 2 bandwidth global configuration command, the configurations that are generated contain an extra input keyword such as mls qos srr-queue input priority-queue input 2 bandwidth. This extra keyword causes an error message if the command is saved and the switch is reloaded.
This is the workaround:
1.
2.
3.
4.
•
When there are many configured secure and sticky MAC addresses on a port, some addresses might be dropped and removed from the configuration when the switch restarts.
There is no workaround.
•
When you configure a unicast MAC address filter that matches a Windows XP 802.1X client MAC address, the switch sends an authentication succeed EAPOL packet to the client followed by an authentication failure EAPOL packet. The Windows XP 802.1X client continues to reauthenticate itself.
There is no workaround.
•
If BPDU filtering is enabled on a trunk port and BPDUs are received on VLANs on which an STP instance is not running, the BPDUs are dropped.
There is no workaround.
Open CMS Caveats
These are the severity 3 CMS configuration caveats:
•
The Port Settings table displays meaningless information in the columns for interface description and duplex cells. This problem occurs for some of the Catalyst 2820 and Catalyst 1900 switches.
There is no workaround.
•
CMS does not validate configuration values for STP port priority before applying them to the switch. When invalid values are applied, the attempt fails without a warning message. This applies to all switches running Cisco IOS Release 12.1 or later.
There is no workaround. Make sure that the configuration values entered are valid.
•
CMS does not validate configuration values for the STP port path cost before applying them to the switch. When invalid values are applied, the attempt fails without a warning message. This applies to all switches running Cisco IOS Release 12.1 or later.
There is no workaround. Make sure that the configuration values entered are valid for the switch type.
•
CMS does not validate configuration values for STP bridge parameters before applying them to the switch. When invalid values are applied, the attempt fails without a warning message. This applies to all switches running Cisco IOS Release 12.1 or later.
There is no workaround. Make sure that the configuration values entered are valid for the switch type.
•
When CMS is operating in read-only mode, an error is reported if Help is opened from the QoS Graph dialog box.
There is no workaround.
•
CMS does not apply shaped bandwidth weights that are invalid. Shaped weights are invalid if the sum of their reciprocals is greater than 1 and the weight of a queue is 0.
There is no workaround.
•
The settings on the Catalyst 2950 LRE ports cannot be modified by using the Port Settings window in CMS.
There is no workaround.
•
You cannot attach an access control list (ACL) to or remove one from an interface when you are in guide mode.
The workaround is to use expert mode to attach an ACL to or remove one from an interface.
•
When you change the Spanning Tree Protocol (STP) port priority on a switch that is running
Cisco IOS Release 12.1(19)EA1 or later, the value must range from 0 to 240 and be in an increment of 16. If you enter a value that is not an increment of 16, the configuration fails, and no error message appears.The workaround is to enter values from 0 to 240 that are in increments of 16.
•
If UplinkFast is enabled and you enter a value in the Path Cost field in the STP Modify Port Parameters window, 3000 is automatically added to the configured-STP cost value. For example, if the path cost is 10, the actual value is 3010. If you disable UplinkFast, the path-cost value changes to its originally configured value of 10.
There is no workaround.
•
CMS does not recognize the CWDM SFP module on the Catalyst 2940 switches, even though the CWDM SPF module is supported by the switches.
There is no workaround.
•
When you launch the IP Multicast wizard, multicast-enabled devices do not appear in the list of multicast-enabled devices.
There is no workaround. The wizard does not display multicast-enabled devices.
•
When you right-click on a Catalyst 3750 switch in the Front Panel view, these pop-up menu options do not appear:
–
–
The workarounds are to select these menu options from the feature bar:
–
–
•
When you click Highlight VLAN Port Membership Modes in the VLAN window of a switch whose front panel is not displayed in Front Panel view, CMS brings the Front Panel view to the foreground, but the Front Panel view of the switch is not displayed and you cannot see the highlighted ports.
Use one of these workarounds:
–
–
•
When you click Previous instead of Finish in the Save Configuration window, the configuration for the interfaces is not applied to the member devices.
The workaround is to click the Finish button to apply the configuration to member devices. If you need to modify the configuration, you need to launch the configuration wizard again.
•
The IGMP Report Window does not list all the entries in the table.
There is no workaround.
Resolved Caveats
These sections describe the caveats that have been resolved in this release.
•
•
Cisco IOS Caveats Resolved in Cisco IOS Release 12.1(19)EA1
These Cisco IOS caveats were resolved in Cisco IOS Release 12.1(19)EA1:
•
Local and Remote SPAN can now be configured at the same time.
•
If an interface on a Catalyst 2970 switch was mapped to queue-set 2 and you disable and then globally re-enable multilayer QoS, the interface is now mapped to the correct egress queue-set (queue-set 2).
Cisco CMS Caveats Resolved in Cisco IOS Release 12.1(19)EA1
This CMS caveat was resolved in Cisco IOS Release 12.1(19)EA1:
•
If a PC running CMS has low memory and CMS is running continuously for 2 to 3 days, the PC no longer runs of out of memory.

TAC Case Priority Definitions
To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.
Priority 1 (P1)—Your 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.
Priority 2 (P2)—Operation of an existing network is severely degraded, or significant aspects of your business operation 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.
Priority 3 (P3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
