1, 2 FAIL
FAIL
The buffer level is nearly exhausted.
The C-LAN is congested, and no buffers are available.
1. Retry command at 1-minute intervals up to 5 times.
2. If command continues to fail, examine the C-LAN port measurements to
determine what ports are heavily utilized and the processor occupancy of
the circuit pack.
Low processor occupancy when C-LAN congested indicates circuit pack
failure.
1. If the problem persists, reset the circuit pack (reset board UUCSS).
2. If congestion recurs, replace the circuit pack.
High processor occupancy indicates the C-LAN is congested due to traffic load.
1. To relieve congestion in the short term, selectively busyout ports (busyout
port UUcSSpp) on the Control LAN circuit pack.
2. To achieve a more permanent resolution, it may be necessary to move
ports on this circuit pack to other Control LAN circuit packs.
3. Consider replacing affected C-LAN ports with new ports.
3 FAIL The C-LAN circuit pack is not operating normally and is congested.
PASS Hardware setting and attached cable type match C-LAN circuit pack
administration. The circuit pack detects no errors.
