Source IP address for SNMP notifications

When you use the snmp-server response-source and snmp-server trap-source commands, note the following behavior:

  • The snmp-server response-source and snmp-server trap-source commands configure the source IP address for IPv4 interfaces only.

  • You must manually configure the snmp-server response-source value if you wish to change the default user-defined interface IP address that is used as the source IP address in SNMP traps (RFC 1517.)

  • The values configured with the snmp-server response-source and snmp-server trap-source commands are applied globally to all interfaces that are sending SNMP responses or SNMP trap PDUs.

  • Only the source IP address field in the IP header of the SNMP response PDU can be changed.

  • Only the source IP address field in the IP header and the SNMPv1 Agent Address field of the SNMP trap PDU can be changed.
