[Cisco] Setting SNMP trap IP source

On a Cisco C3560 switch, after a maintenance work that changed the management VLAN, syslog started showing the following message:

 %IP_SNMP-4-NOTRAPIP: SNMP trap source Vlan123 has no ip address

Vlan123 is the previous management VLAN.


I managed to stop the log by configuring SNMP trap IP source as follows:

switch(config)#snmp-server trap-source vlan 321

where VLAN 321 is the new management VLAN.
