You can identify the type of crash that has occurred from the "SIG=" value in the show context slot <slot> command

output. See the

SIG Code Table

Here are some links that provide more information on the three most common types of line card crashes, and explain

how to troubleshoot them:

Software-forced crash (SIG=23)

Bus Error (SIG=10)

Cache Parity Exception (SIG=20)

In the example above, the line card has crashed due to a "software-forced crash" and, as the name suggests, a software

exception has caused the reload. Once you have determined the cause and collected the necessary output, you can

check for a bug in your Cisco IOS software release using the

Check the Current Status of the Line Card

When you have determined whether the problems are system errors in the log or an actual crash, you must check the

current status of the line card to see whether it has recovered from the fault that has occurred. In order to identify the

status of individual line cards, you can either examine the Light Emitting Diodes (LEDs) located on the front of the

card, or issue the show led command. Here is a sample output:

Router#show led
