Configuring a Source Interface for SNMP Notifications

You can configure SNMP to use the IP address of an interface as the source IP address for notifications. When
a notification is generated, its source IP address is based on the IP address of this configured interface.
You can configure a source interface as follows:
• All notifications sent to all SNMP notification receivers.
• All notifications sent to a specific SNMP notification receiver. This configuration overrides the global

will use the same interface to send the trap. The source interface IP address defines the source address
inside of the SNMP trap, and the connection is opened with the address of the egress interface as source.
