Fabric Ping Failure

Fabric ping failures occur when either a line card or the secondary GRP fails to respond to a fabric ping request from
the primary GRP over the switch fabric. Such failures are a problem symptom that you must investigate. They are
indicated by these error messages:
%GRP-3-FABRIC_UNI: Unicast send timed out (1)
%GRP-3-COREDUMP: Core dump incident on slot 1, error: Fabric ping failure
%LCINFO-3-CRASH: Line card in slot 1 crashed

messages.

Error Messages

If you experience any error messages related to one of the line cards, you can use the

issue of the line card, whereas others indicate a Cisco IOS software bug, or a hardware issue on another part of the
router. This document does not cover all these messages.

Test the Line Card for Hardware Failure

Line card Field Diagnostic software is designed to identify any faulty line card within a Cisco 12000 (all 12xxx series)
router. Prior to Cisco IOS software release 12.0(22)S, the Field Diagnostic software was embedded within the Cisco
IOS software. From Cisco IOS software release 12.0(22)S onwards, this software has been unbundled, and you can
download it from CCO through the
120XX platform). It is still run from a command initiated while running Cisco IOS software, but you must specify the
source (either Trivial File Transfer Protocol (TFTP) boot server, or PCMCIA Flash memory) on the command line. All
Field Diagnostics commands are run at the enable level of Cisco IOS software.

Cisco IOS Software Releases Later than 12.0(22)S

From Cisco IOS software release 12.0(22)S onwards, Cisco Systems has unbundled the Cisco 12000 Field Diagnostic
line card image from the Cisco IOS software image. In earlier versions, diagnostics could be launched from the
command line and the imbedded diagnostic image would be launched. In order to accommodate customers with 20Mb
Flash memory cards, the Field Diagnostic software is now stored and maintained as a separate image: c12k-fdiagsbflc-
mz.xxx-xx.S.bin (where x is the version number). This means that for a customer to launch Field Diagnostics, this
image must be available on a separate Flash card or TFTP boot server. The latest version is always available on
