Problem Description

TNC/TSC cards in a node provisioned in multi-shelf mode autonomously reset every 100 days.

This problem does not affect nodes that are configured as single-shelf nodes.

All TNC/TSC cards that run the following releases are affected: 9.203, 9.211, 9.3, 9.4.

This issue is fixed in these software releases: 9.60, 9.401, 9.22, 9.213.

Background

Due to a defect in the low-level software, an internal counter reaches an invalid value after 100 days and triggers the software to perform the autonomous reset on the TNC/TSC card.

This issue is fixed in these software releases: 9.60, 9.401, 9.22, 9.213.

Problem Symptoms

The TNC/TSC cards reset and go through a warm restart of the processor on the card. It is possible for multiple or all TNC/TSC cards on a node to reset at the same time.

Workaround/Solution

The workaround for this issue is to perform a manual reset on the TNC/TSC cards in the system every 90-95 days. By performing the manual reset, you can monitor the manual reset in order to allow the TNC/TSC cards to be reset in a controlled operation.

Cisco recommends that the TNC/TSC cards of a node be reset in a staggered manner to remove the possibility of all TNC/TSC cards resetting at the same time if this issue occurs.You should reset a TNC/TSC card, confirm proper recovery and operation, and wait 15 minutes before resetting the next TNC/TSC card.

Cisco also recommends that you cycle through all standby (STBY) TNC/TSC cards before resetting the ACT cards.
