SNMP in Cat os not working

SNMP is enabled in Cat os sup-720 in 8.4(5). No response for the SNMP server poll and no traps are forwarded to SNMP server. Any one experienced this kind of issue can throw some light on this.

Find the configuration and ‘sh snmp’ output

Re: SNMP in Cat os not working

i cant see any host configured to receive the traps mate. Not sure of the catos command but something like snmp-server host 1.1.1.1 public

Re: SNMP in Cat os not working

Thank you for the thought. You are right we have equivalent command “set snmp targetaddr” but it didn’t work. My priority is not to receive trap I should be able to read the MIB’s by polling with the community string. Which in my case is not happening? Is there any limitation? My SNMP server says ‘please set the community string in the host’ where in I have enabled snmp service and configured string.

Re: SNMP in Cat os not working

SNMP server needs to add to IP permit list.

set ip permit X.X.X.X X.X.X.X snmp

It solved the issue.

Thank you for your time romccallum.
