Understanding SPA Automatic Recovery
When Gigabit Ethernet SPAs encounter thresholds for certain types of errors and identify a fatal error, the
SPAs initiate an automatic recovery process.
You do not need to take any action unless the error counters reach a certain threshold, and multiple attempts
for automatic recovery by the SPA fail.
The Gigabit Ethernet SPAs might perform automatic recovery for the following types of errors:
•
SPI4 TX/RX out of frame
•
SPI4 TX train valid
•
SPI4 TX DIP4
•
SPI4 RX DIP2
When Automatic Recovery Occurs
If the SPI4 errors occur more than 25 times within 10 milliseconds, the SPA automatically deactivates and
reactivates itself. Error messages are logged on the console indicating the source of the error and the status
of the recovery.
If Automatic Recovery Fails
If the SPA attempts automatic recovery more than five times in an hour, then the SPA deactivates itself and
remains deactivated.
To troubleshoot automatic recovery failure for a SPA, perform the following steps:
SUMMARY STEPS
1.
Use the
show hw-module subslot slot/subslot oir
command to verify the status of the SPA. The status is
shown as
“
failed
”
if the SPA has been powered off due to five consecutive failures.
2.
If you verify that automatic recovery has failed, perform OIR of the SPA. For information about performing
OIR, see the
Preparing for Online Insertion and Removal of a SPA
section.
3.
If reseating the SPA after OIR does not resolve the problem, replace the SPA hardware.
