CSS11500 - specifying which interface to send out snmp traps

Unanswered Question
Mar 31st, 2009


Can some one please explain how I can define which interface to use to send out snmp traps generated on my css. I understand how to set the source IP address in the traps generated by the CSS however I am struggling to get it to send them from the correct interface. In addition can the CSS physically send the traps from its management interface?

Many thanks

I have this problem too.

As a best practice we should use Loopback interface to send SNMP traps. If CSS supports (ideally it must support) create a Loopback interface & specify that in snmp: snmp-server trap-source Loopback0

Thanks Giles, does it just pick the source interface at random or is there some logic behind the choice made. (ie lowest vlan number)Thanks
