Inquiry for CSM tech-support utilization command.

[kwansoo kim]

Dear,

I use this command 'show module csm [slot#] tech-support utilization to check status of csm.

For some issue, i need to know meaning of below's unicast value from result

Does unicast mean unicast traffic rate through csm?

What is the unit of 341260/s and max value to be 100%, degree(value) to get impact services through csm?

Can i re-size limitation manually?

please help me on this.

Thanks,

HI,

MACs   

     MAC0         0%  (83474/s)    591 average size.

     MAC1         0%  (70432/s)    556 average size.

     MAC2         0%  (94381/s)    572 average size.

     MAC3         0%  (92982/s)    578 average size.

UNICAST     99% (341260/s)

MULTICAST    0%      (4/s)

BROADCAST    0%      (6/s)

you can see that each of the MACx refers to the 4 ports of the CSM, the amount of packets

per second and the average in the packet size.

UNICAST, MULTICAST and BROADCAST refer to the destribution in percentage on the amount of

unicast frames, multicast frames and broadcast frames that have got to the CSM.

The sum for the 3 counters should be 100%. So, 99% of the frames that got to the CSM were

unicast frames.

it means that you have more UNICAST than BROADCAST/MULTICAST: I'd say that's very good

a different example: if you don't run any client-server traffic and the CSM just received control protocol packets (BPDU, CDP, etc...), you end up with just MULTICAST:

MACs

     MAC0         0%      (7/s)     71 average size.

     MAC1         0%      (0/s)      0 average size.

     MAC2         0%      (0/s)      0 average size.

     MAC3         0%      (0/s)      0 average size.

     UNICAST      0%      (0/s)

     MULTICAST  100%      (7/s)

     BROADCAST    0%      (0/s)
