(remainder of output omitted)
The type of failure that has occurred in the show context slot 2 example is identified by the underlined
SIG= value. The three most common types of SIP failures are:
•
•
•
In the example above, the SIP has failed and has caused a reload because of a software forced crash
exception. Once you have determined the cause and collected the necessary output, you can check for
any caveats in your Cisco IOS software release using the Bug Toolkit (available to registered Cisco.com
users only).

Checking the Current Status of the SIP

Once you have determined if the problems are caused by system errors in the log or an actual crash, it is
important to check the current status of the SIP to see if it has recovered from the failure. The status of
individual SIPs can be identified by using the show led command.
