Verify the CPU utilization.
OmniSwitch 6624/6648 and 7700/7800/8800
The CPU utilization of CMM can be viewed by using the command:
-> show health
* - current value exceeds threshold

The above command shows the receive, transmit/receive, memory, CPU, temperature CMM and tempera-
ture CMM CPU statistics for current, 1 minimum average, 1 hour average and 1 hour maximum. All the
values should be within the threshold. Anything above the threshold depicts that some abnormal behavior.
Normally 1 hour average maximum might be high if the switch was booted up in the last hour but it should
be fairly steady during normal operation.
If none of the above are above the threshold then the next step is to try to isolate the problem to a particu-
lar NI. Due to the distributed architecture every NI has it own CPU to perform some operations locally. It
is possible that a particular NI might be at high CPU utilization at a time when other NI as well as the CPU
are within the thresholds.
If none of the above are above the threshold then the next step is to try to isolate the problem to a particu-
lar NI (or a switch within an OmniSwitch 6624/6648 stack) with the show health slot_number CLI
command:
-> show health 5
* - current value exceeds threshold

The principle for the health of an NI is the same as for CMM.
