there are a lot of messages in log like this:
%PLATFORM_RPC-3-MSG_THROTTLED: RPC Msg Dropped by throttle mechanism: type 3, class 21, max_msg 8, total throttled 1355

And the CPU utilization turns to 47% from 6%. There is no flow in all ports except vlan1.

Please check the link below.
Seems like there are too many ARP requests generated out of the some port which has security feature like NAC enabled on it.

Could you tell me how to confirm it ?
And I have checked that there is no snmp-server ifindex persist configured.
Thank you very much!

Can you post the configuration of the switch? specifically the switch port configuration.

there are a few multicasts in 3 ports and only the 3 ports are configured IP address.

The above link contains the unsupported commands in 3750. Can you please try removing the commands listed.

I cannot access the link, "Forbidden File or Application" is appeared.
any else could I do ?

There is no unsupported commands in my switch.
And I find a strange thing about flow. There are 2 vlans in switch, the input rate of vlan1 is 13Mb/sec and the output rate of vlan2 is 12Mb/sec. There is no flow in other ports both input and output. Why would be this ?
