Hi Paul,

mine looks like that and I'd rx traps in Netsight...



The only difference I'd see is the SNMP group that I've configured.

Is the switch IP on VR-Default - you'd check it with "show vlan"

Here a article that I've found about trap configuration...

I didn't aware that "show vlan" is also part of troubleshooting process. Thanks.

Please add the "configure snmpv3 add group xxxxx" per my example in the screenshot above.

I've tried it and if I delete this command on my switch then I also don't get traps from the switch and the SNMP trap counter is 0.

Hi Paul,
I'm checking up on older threads and wanted to see if you were able to get this one sorted out.

Hi Drew,

we may close the case. by using "sh management" and snmp trap will sent out, eg. link up/down.

Thanks for your review.
