Re: [Netdisco] arp nip and cpu spikes

[Max B. <ma...@wa...>]

Matthew,

This was a problem with much older Catalyst 4000 devices and some 1900's,
but I haven't seen it with the 6500's.  You might try seeing if there is a
difference if you bulkwalk or if you do a normal SNMP get.

Try:

    snmpwalk -v2c -cpublic your_6513 atNetAddress atPhysAddress

vs:

    snmpbulkwalk -v2c -cpublic your_6513 atNetAddress atPhysAddress

and see if you see any noticeable difference.

-m
