CE-1000 card on MSPP causes traffic outage with software versions earlier than Version 9.23 

Problem Description

The CE1000-4 card raises a CARLOSS alarm, which causes a drop in traffic for the port. This is due to a bug in the timer software that occurs approximately every 828 days when auto negotiation is enabled on the ports.

Background

This issue occurs when a timer counter reaches the maximum count, the timer has not been reset to zero in approximately 828 days, and auto negotiation is enabled. The software versions prior to Version 9.23 improperly declare an auto negotiation issue and the CARLOSS alarm is raised.

Problem Symptoms

When the CE-1000 card is not reset for approximately 828 days, the software improperly sees an auto negotiation issue and a CARLOSS alarm is declared on the card. This causes a drop in traffic for the port.

Workaround/Solution

Perform a soft reboot of the CE-1000 card before 828 days, or disable auto negotiation. 

Note: This issue is fixed in Versions 9.23 and 9.231.
