Cluster Compatibility

This section describes how to choose command and standby command switches when a cluster consists of a mixture of Catalyst switches. When creating a switch cluster or adding a switch to a cluster, follow these guidelines:

•When you create a switch cluster, we recommend configuring the highest-end switch in your cluster as the command switch. Table 2 lists the cluster capabilities and Cisco IOS releases for the switches. The switches are listed from highest- to lowest-end switch.

•If you are managing the cluster through CMS, and the command switch is running Cisco IOS Release 12.1(19)EA1 or later, the switch that has the latest software release does not have to be the command switch. It is also not required that the highest-end switch in your cluster be the command switch if the command switch is running Cisco IOS Release 12.1(19)EA1 or later.

•The standby command switch must be the same type as the command switch. For example, if the command switch is a Catalyst 3750 switch, all standby command switches must be Catalyst 3750 switches.

Table 2 Switch Software and Cluster Capability 

Switch	Cisco IOS Release	Cluster Capability
Catalyst 3750	12.1(11)AX or later	Member or command switch
Catalyst 3560	12.1(19)EA1b or later	Member or command switch
Catalyst 3550	12.1(4)EA1 or later	Member or command switch
Catalyst 2970	12.1(11)AX or later	Member or command switch
Catalyst 2955	12.1(12c)EA1 or later	Member or command switch
Catalyst 2950	12.1(5.2)WC(1) or later	Member or command switch
Catalyst 2950 LRE	12.1(11)JY or later	Member or command switch
Catalyst 2940	12.1(13)AY or later	Member or command switch
Catalyst 3500 XL	12.0(5.1)XU or later	Member or command switch
Catalyst 2900 XL (8-MB switches)	12.0(5.1)XU or later	Member or command switch
Catalyst 2900 XL (4-MB switches)	11.2(8.5)SA6 (recommended)	Member switch only1
Catalyst 1900 and 2820	9.00(-A or -EN) or later	Member switch only

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.

CMS is not forward-compatible on command switches running Cisco IOS 12.1(14)EA1 and earlier. This means that if a member switch is running a release that is newer than the release running on the command switch, the new features are not available on the member switch. If the member switch is a new device running a release that is later than the release on the command switch, and if the command switch is running a release earlier than Cisco IOS Release 12.1(19)EA1, the command switch cannot recognize the member switch, and the Front Panel view displays it as an unknown device. You cannot configure any parameters or generate a report through CMS for that member; instead, you must launch the Device Manager application to configure and to obtain reports for that member.

If you have a cluster with switches that are running different versions of Cisco IOS software, features added on the latest release might not be reflected on switches running the older releases. 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.

Some early Cisco IOS releases do not support clustering.

For more information about clustering and CMS, refer to the software configuration guide.

Software Compatibility

For information about the recommended platforms for web-based management, operating systems and browser support, and CMS plug-in guidelines, refer to the "Getting Started with CMS" chapter of the software configuration guide.

Windows

This release uses a CMS plug-in to run CMS. You can download the latest CMS plug-in for Windows from this URL:

http://www.cisco.com/pcgi-bin/Support/ClusterMgmtSuite/cms_plugin_redirect.cgi?platform=windows&version=1.1

Solaris

This release uses a CMS plug-in that replaces the Java plug-in. You can download the latest CMS plug-in for Solaris from this URL:

http://www.cisco.com/pcgi-bin/Support/ClusterMgmtSuite/cms_plugin_redirect.cgi?platform=solaris&version=1.1

New Features

These sections describe the new supported hardware and the new software features provided in this release:

•"New Hardware Features" section

•"New Software Features" section

New Hardware Features

For a list of all supported hardware, see the "Hardware Supported" section.

New Software Features

Cisco IOS Release 12.1(19)EA1c contains these features:

•Ability to provide power to connected Cisco prestandard and IEEE 802.3af-compliant powered devices from all Catalyst 3750-24PS, 3750-48PS, 3560-24PS, and 3560-48PS switch 10/100 Ethernet ports if the switch detects that there is no power on the circuit.

•The Catalyst 3750-24PS and 3560-24PS switches can provide 15.4 W of power on each 10/100 port; the Catalyst 3750-48PS and 3560-48PS switches can provide 15.4 W of power to any 24 of the 48 10/100 ports, or any combination of ports can provide an average of 7.7 W of power at the same time, up to maximum switch power output of 370 W.

• Automatic detection and power budgeting; the switch maintains a power budget, monitors and tracks requests for power, and grants power only when it is available.

---

Note The Cisco IP Phone 7970G can operate in low- and high-power modes. For high-power mode and full functionality, we recommend that you use an external power adapter. The phone functions if power is provided by Cisco prestandard or IEEE 802.3af PoE, but it has reduced power, and the display is at half brightness. The Catalyst 3550, 3560, and 3750 switches can provide 15.4 W per port. However, this release does not support CDP enhancements to allow negotiation with the Cisco IP Phone 7970G to cover its wider power range.

Refer to the Cisco IP Phone 7970 Administration Guide for Cisco CallManager for details.

---

---

Note On PoE switches, CDP messages enable the switch to refine the power consumption of Cisco powered devices with more accuracy than what is available by using generic IEEE Classes.

On 48-port PoE switches, CDP allows the switch to optimize the available 370 W budget of PoE across Cisco powered devices.

---

•CMS support for these features:

–The option to install CMS on your computer rather than to download it from the cluster every time you start a CMS session.

---

Note CMS is downloaded to your browser each time you launch CMS. You can increase the speed at which CMS loads by permanently installing CMS on your PC or workstation. Select CMS > Installation and Distributions, and click Install. CMS is installed locally and will load faster the next time that you launch it.

---

–A feature bar, which offers networking features to configure and reports, graphs, and statistics to display. These options were previously on the menu bar, which is now dedicated to CMS service options. You can choose features from menus on the Features tab or search for them on the Search tab.

–Device-specific online help. Help topics appear below labels that name the devices to which the information applies. Topics appear only for the networking features in the cluster.

–This release uses a CMS plug-in for Solaris and Windows that replaces the Java plug-in.

---

Note You must download the latest CMS plug-in to run CMS for this release.

---

You can download the latest plug-ins from these URLs:

http://www.cisco.com/pcgi-bin/Support/ClusterMgmtSuite/cms_plugin_redirect.cgi?platform=windows&version=1.1

http://www.cisco.com/pcgi-bin/Support/ClusterMgmtSuite/cms_plugin_redirect.cgi?platform=solaris&version=1.1

For more information about new CMS features, click Help > What's New from the online help.

For a detailed list of key features for this software release, refer to the software configuration guide for your switch.

Resolved Caveats for All Switches

These resolved caveats are applicable to all Catalyst switches running this release:

•CSCec82728

A transient spanning tree loop no longer occurs when rapid-PVST+, MSTP/RSTP is running and the root bridge has aged out.

•CSCed27956

A vulnerability in Transmission Control Protocol specification (RFC793) has been discovered by an external researcher. The successful exploitation enables an adversary to reset any established TCP connection in much shorter time then was previously publicly discussed. This can lead to a Denial of Service attack. Depending upon the attacked protocol, a successful attack may have additional consequences beyond terminated session, which must be considered. This attack vector is only applicable to the sessions which are terminating on a device (e.g., router, switch, computer) and not to the sessions that are only passing through the device (e.g., transit traffic that is being routed by a router).

All Cisco products which contain TCP stack are susceptible to this vulnerability.

This advisory is available at http://www.cisco.com/warp/public/707/cisco-sa-20040420-tcp-ios.shtml, and it describes this vulnerability as it applies to Cisco products that run Cisco IOS® software.

A companion advisory that describes this vulnerability for products that do not run Cisco IOS software is available at http://www.cisco.com/warp/public/707/cisco-sa-20040420-tcp-nonios.shtml.

•CSCed29169

The IP Internet Group Management Protocol (IGMP) report expiration timer no longer expires in 1 second, no matter how you configured the IGMP query-max-response-time setting. Having the timer set to 1 second, regardless of how it was configured, sometimes caused multicast receiver ports to be prematurely removed from their multicast group on a given VLAN.

•CSCed38527

•CSCed58872

The topology change counter now operates in multiple spanning-tree (MST) mode.

Resolved Caveats for Catalyst 3750, 3560, and 2970 Switches

This resolved caveat is applicable to these switches:

•CSCec50040

Using the show controllers ethernet-controller <interface-id> [phy] privileged EXEC command on a 1000BASE-T copper port or on an SFP module port no longer causes the link to go down or to go up and down continuously.

Resolved Caveats for Catalyst 3750 Switches

These resolved caveats are applicable to these switches:

•CSCed33857

When the switch is operating in multiple STP (MSTP) mode, stack member switches now forward traffic that belongs to newly created VLANs on an EtherChannel or trunk.

•CSCed50935

When Dynamic Host Configuration Protocol (DHCP) snooping is enabled, the software no longer forwards all routed IP packets after a stack master election.

Open Cisco IOS Caveats for Catalyst 3750 and 3560 Switches

This is the severity 3 Cisco IOS configuration caveat:

•CSCed09484

When a type 1 Token Ring patch cable is connected to a PoE port, these syslog messages appear every 10 seconds:

–00:01:06: %ILPOWER-7-DETECT: Interface Fa1/0/1: Power Device detected: Cisco PD

–00:01:06: %ILPOWER-5-POWER_GRANTED: Interface Fa1/0/1: Power granted

–00:01:06: %ILPOWER-3-CONTROLLER_PORT_ERR: Controller port error,

–Interface Fa1/0/1: Power Controller reports power Tstart error detected

There is no workaround. However, when a valid link partner is connected to the PoE port, it operates normally and without user intervention.

Opening a TAC Case

Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Case Open Tool automatically recommends resources for an immediate solution. If your issue is not resolved using the recommended resources, your case will be assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:

http://www.cisco.com/tac/caseopen

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.

To open a case 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: 1 800 553-2447

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.
