3750 stack cpu issue

I have 4 WS-C3750-24TS-S in stack. The command "show cpu history" shows in the 72 hour table cpu load of 100% instances. However I,m monitoring the cpu load with rmon and the alarm never fires. My high level threshold is set at 60%.

I tested the rmon by setting the threshold at 5%. this works fine.

Can anyone help me with this?

Thanks in advance.

Re: 3750 stack cpu issue

RMON is disabled by default; no alarms or events are configured.

Only RMON 1 is supported on the switch.

To verify use this commands.

Switch# show interfaces interface-id transceiver detail

For further information about configuring the Rmon Alarm & Events click this link.

Re: 3750 stack cpu issue

Thanks for your reply. However the rmon not working isn't the issue. When I lower my threshold rmon works fine. The real issue is the high cpu load in the "72 hour"table on my 3750 stack and rmon doiing nothing with it.

Re: 3750 stack cpu issue

This will sound crazy, but I have seen issues where a bad conector cable has caused VERY high CPU utilization rates.

HTH,

Hi Brandon. It doesn't sound crazy to me. I will check the cabling.

Thnx
