Chapter 1 General Troubleshooting
ASIC Errors
– Address—Address that encountered the SBE
– Data—Actual error data
• PARITY Errors—Parity error in all applicable memory
Reported to PM as Major.
• Cyclic redundancy check (CRC) Errors—CRC errors in EIO other links.
Not reported for each occurrence. When the threshold is reached it is reported as Major to the PM.
• GENERIC Errors—Errors that do not fall under any of the other classifications.
Threshold and alarm reporting is done.
• RESET Errors—Logged for each reset instance of the ASIC.
Reported to PM when threshold is exceeded.
Error data:
– Interrupt status—Interrupt status bits due to ASIC reset.
– Halt status—Halt status bits.
– Reset node key—Key for the error node that causes the reset.
– Time—Reset time.
The following ASIC error fault severities are supported:
• Critical—Affected component is unusable or card is reset if no redundant card exists
• Major—Partially service affecting fault or if redundant card, do a failover otherwise the card runs
in degraded mode
• Minor—Non-service affecting fault
• OK—No fault
Use the show asic-errors command to view if any ASIC errors have occurred on nodes. The following
example shows the output of the show asic-errors command.
RP/0/RP0/CPU0:router# show asic-errors plim asic 0 all location 0/0/CPU0
