Release Notes for Catalyst 6500 Series Switch and Cisco 7600 Series Wireless LAN Services Module Software Release 2.4.0


April 26, 2007

This publication describes the features, modifications, and caveats for the Catalyst 6500 series and Cisco 7600 series Wireless LAN Services Module (WLSM) software release 2.4.0.

This maintenance release does not introduce new features and does not resolve caveats; the purpose of this release is to maintain compatibility between WLSM software and access point WDS software.


Note For installation and configuration procedures for the WLSM, refer to the Catalyst 6500 series and Cisco 7600 series Wireless LAN Services Module documentation at this URL:

12.2(18)SXF2


Solution Requirements

In addition to the hardware and software requirements, the WLSM also requires the following:

Cisco Aironet 1100, 1130AG, 1200, 1230AG, and 1240AG Series Access Points and Cisco Aironet 1300 Series Outdoor Access Point/Bridge using Cisco IOS Release 12.2(15)XR or Release 12.3(2)JA or later, Cisco Aironet 1130 Series Access Point using Cisco IOS Release 12.3(2)JA or later, or Cisco Aironet 1310 Outdoor Access Point/Bridge (configured in access point mode) using Cisco IOS Release 12.3(2)JA or later

CiscoWorks Wireless LAN Solution Engine (WLSE) release 2.7(1) or later

Limitations and Restrictions

This section describes general limitations and restrictions:

In software release 1.1.1 through 1.4.1, you can install one WLSM in a chassis.

In software release 2.1.1, you can install two WLSMs, which requires Cisco IOS Release 12.2(18)SXF2.

You cannot configure wireless clients in the same subnet as wired clients.

You cannot map multiple SSIDs to a single network ID.

You cannot configure QoS on tunnel interfaces in systems with a PFC3A. There is full QoS support in systems with a PFC3B or PFC3BXL.

If you upgrade your Supervisor 720 to Cisco IOS Release 12.2(18)SFX2, you must be running Cisco Wireless LAN Services Module software version 1.4.3 or greater on your WLSM.

Documentation Updates

The Cisco Catalyst 6500 Series Wireless LAN Services Module: Detailed Design and Implementation Guide contains an incorrect entry pertaining to default gateway IP addresses

The WLSM Failover—The "DHCP Configuration" section on page 56 states that the DHCP server must be configured to return both IP address to the client. This is not correct because the specific default gateway that a client uses is ignored by the access point and all traffic is sent to the upstream tunnel address. The tunnel address changes after the access point registers with the backup WDS and new tunnels are created by its corresponding Supervisor 720 module. Only one gateway is needed.

This discrepancy is documented in open caveat CSCej53619.

CSCsc05022—High CPU workaround for 240 mobility routing configuration

When a large number of mGRE tunnels are configured on the Supervisor 720 as part of the 240 mobility support feature, a large number of advertisements occur from the routing protocol. The advertisements can cause a high CPU utilization rate, which results in reduced performance.

To help alleviate this problem, first turn off all router protocol advertisements using the router's passive-interface default command. Then specify interfaces, VLANs, and networks for which you want advertisements to be broadcast. The following table shows this workaround for EIGRP:

Command
Remarks

router eigrp

Designates router protocol to address.

passive-interface default

All interfaces will not send EIGRP advertisements.

no passive-interface interface

Enter for all physical interfaces for which you want advertisements sent so that neighbors are formed and routes exchanged.

no passive-interface vlan

Enter for all VLANs to which EIGRP advertisements should be sent.

network x.x.x.x

Include all tunnel interfaces with a separate network command. Also include other networks that need to be advertised.

Resolved Caveats in Release 2.4.0

There are no resolved caveats in release 2.4.0.
