My 3750 stack running ipservicesk9-m 12.2(53)SE is heavily loaded at times, and the log shows that it is the snmpengine that causes the load.
%SNMP-3-CPUHOG: Processing GetNext of lldpRemEntry.6.0
and that this task has been running for some time and that it is the "process = SNMP ENGINE".
The switch is running a pretty simple configuration, with 10 vlans, one ospf process and 5 of the 2x12 interfaces in use. All the ports are trunks to other switches. 2 of the ports are trunks allowing only one vlan for the routing to the core router, one of this trunks are forwarding and the other are blocking.
There are noe specific snmp configuration, only 2 lines:
snmp-server community xxxxxxx RW 1
snmp-server community yyyyyyy RO
I've been trying google for similar problems, but not sure what causes this.
Can anyone give some help understanding this problem and solve it?
