Process Snmp (PDU Dispatcher) causes High CPU value


I have a Catalyst Switch 6000. Inoticed that after the execution of the job inventory in LMS, and after the snmp queries reached the equipement, the cpu value reached 98-99 % due to the process : PDU DISPATCHER (what’s it ?)

I have also a script running in the switch to observe the differents logs. For exemple, when high cpu is obtained, the message bellow appear :

« %SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input

« %SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input

« %SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input


Could you give me any idea or help ?

Thanks in advance.

Re: Process Snmp (PDU Dispatcher) causes High CPU value

This msg is normally generated when to many snmp request overrun the buffer allocated for such requests. There are a number of things that can cause this as well as a number of known issues that can be worked around using snmp views. Without reviewing show logging and other information available in a show tech, hard to say what the best method to resolve this. Should probably open a TAC SR to troubleshoot the issue further...
