Usage Guidelines

This command was added in Cisco IOS Release 11.2 GS to support the Cisco 12000 series Gigabit

Switch Routers.

Note The diag command must be executed from the GRP main console port.

slot-number Slot number of the line card you want to test. Slot numbers range from

0 to 11 for the Cisco 12012 and 0 to 7 for the Cisco 12008. Slot

numbers for the CSC are 16 and 17 and for the FSC are18, 19, and 20.

halt (Optional) Stops the ﬁeld diagnostic testing on the line card.

previous (Optional) Displays previous test results (if any) for the line card.

post (Optional) Initiates a EPROM-based extended power-on self-test

(EPOST) only. The EPOST test suite is not as comprehensive as the

ﬁeld diagnostics, and a pass/fail message is the only message

displayed on the console.

verbose [wait] (Optional) Enables the maximum status messages to be displayed on

the console. By default, only the minimum status messages are

displayed on the console. If you specify the optional wait keyword, the

Cisco IOS software is not be automatically reloaded on the line card

after the test completes successfully.

wait (Optional) Stops the automatic reloading of the Cisco IOS software on

the line card after the successful completion of the ﬁeld diagnostic

testing. If you use this keyword, you must use the microcode reload

slot global conﬁguration command, or manually remove and insert the

line card (to power it up) in the slot so that the GRP will recognize the

line card and download the Cisco IOS software image to the line card.
