mode:

To stop ﬁeld diagnostic testing on a line card, perform the following tasks in privileged EXEC mode:

Note When you stop the ﬁeld diagnostic test, the line card remains down (that is, in an unbooted

state). In most cases, you stopped the testing because you need to remove the line card or replace the

line card. If that is not the case and you want to bring the line card back up (that is, on-line), you

must use the microcode reload global conﬁguration command or power cycle the line card.

Storing Line Card Crash Information

This section explains how to enable storing of crash information for a line card and optionally

specify the type and amount of information stored. Technical support representatives need to be able

to look at the crash information from the line card to troubleshoot serious problems on the line card.

The crash information contains all the line card memory information including the main memory

and transmit and receive buffer information.

Caution Use the exception linecard global conﬁguration command only when directed by a

technical support representative and only enable options that the technical support representative

requests you to enable.
