Hi there,

 

Can you share the following (change X for the SVI you mentioned you delete/add):

 

show run ospf
show run int vlan X << where X is the SVI you mentioned
show run vrf test
show accounting log | i i ospf|vlan.X << Change X for the SVI you mentioned
show cores
show system internal mts buff summary
show system reset-reason

Is this something you can reproduce consistently or it just happened this one time? 

 

Thanks,

Specify the source interface for informs and traps if the management VRF instance is not being used. This allows security devices such as firewalls to identify the source of the SNMP packet. If the source interface or IP address is not specified the primary IP address on the originating (outbound) interface is selected. The inform feature only applies to SNMP v2c and v3. You can configure the source interface globally for all SNMP hosts or per SNMP host.

Global Configuration:

 n7000(config)# snmp source-interface informs loopback0
 n7000(config)# snmp source-interface traps loopback0
Per Server Configuration:

 n7000(config)# snmp-server host a.a.a.a source-interface loopback0
