Cisco Catalyst 5000 Series Switches

Revised November 25, 1998

Products Affected

Problem Description

On Catalyst 5000 switches running Supervisor software 4.3(1a) or later, the LANE module(s) running TR-LANE software prior to release 70.1(4) will fail to come online.

Catalyst 5000 LANE blades (WS-X5156, WS-X5157, WS-X5158) running:

c5atm-trlane.70-1-1.bin

c5atm-trlane.70-1-2.bin

c5atm-trlane.70-1-3.bin

will fail to come online if the Catalyst 5000 has been upgraded with Supervisor image cat5000-sup.4-3-1a.bin or later.

This is addressed in Cisco DDTS CSCdk58188. See the "DDTS" section below for details.

Workaround/Solution

To prevent an incompatibility between the Supervisor and TR-LANE images, upgrade the TR-LANE software on the LANE module to 70.1(4) before upgrading Catalyst 5000 Supervisor images to 4.3(1a) or above.

If the Supervisor has been upgraded with cat5000-sup.4-3-1a.bin before c5atm-trlane.70-1-4.bin has been downloaded to the LANE module, back out the upgrade with the following steps:

1. Downgrade the software on the Supervisor module to a release prior to 4.3(1a)

2. Upgrade the TR-LANE software on the LANE module with image c5atm-trlane.70-1-4.bin or later

3. Upgrade the software on the Supervisor module with image cat5000-sup.4-3-1a.bin or later
