Problem Description

On Cisco 12000 Routers booted with Cisco IOS 12.0(26)S4 or 12.0(27)S4, when two ATM interfaces of either Engine3(ISE) or Engine2 ATM line cards are configured, adding a service policy to the lower numbered interface and then using the exit command causes ping to be disabled on the CE connected to the higher numbered interface.

Background

This problem is currently seen on Cisco 12000 routers containing Engine 3 (ISE) based 4 port ATM or Engine 2 based 8 port ATM line cards.

Any action that causes the affected ATM PVC to be reinitialized restores traffic forwarding.

Note: This field notice may be updated at a later date if additional Cisco 12000 ATM line cards are verified to be experiencing this same problem.

Problem Symptoms

When an ATM PVC is configured with an egress service policy, exiting from the PVC configuration mode by entering the exit command may cause traffic that is forwarded from other PVCs on the line card to be dropped.

Workaround/Solution

Workarounds:

  1. Issue the end command to exit configuration mode instead of the exit command.

  2. Issuing a shut/no shut on the affected interfaces clears the problem.

Resolution:

A software fix for this problem has been integrated into the following Cisco IOS releases for Cisco 12000:

  • 12.0(27)S5

  • 12.0(28)S2

  • 12.0(30)S1
