nnsnmpSourceAddress
Module: SNMP-MIB
OID (symbolic): SNMP-MIB::nnsnmpSourceAddress
OID (numeric): 1.3.6.1.4.1.562.73.1.1.1.5.1.3
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: Source IP address to be used on SNMP TRAPS sent by the agent.Default is ethernet 0 's IP address.Use 0.0.0.0 to unconfigure.
What is nnsnmpSourceAddress?
This read-write object sets the source IP address the agent uses when sending SNMP traps, defaulting to the address of ethernet 0; setting it to 0.0.0.0 unconfigures the override. An admin sets this on a multi-homed device to ensure traps are sent from a consistent, expected source address (such as a loopback or management interface) rather than whatever interface routing happens to pick. Setting it to a dedicated management IP address ensures all traps from this device appear to originate from that address, simplifying trap-receiver filtering.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.562.73.1.1.1.5.1.3 snmpwalk -v2c -c public <target> SNMP-MIB::nnsnmpSourceAddress
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.562.73.1.1.1.5.1.3.1 snmpget -v2c -c public <target> SNMP-MIB::nnsnmpSourceAddress.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.562.73.1.1.1.5.1.3.1 a <value>
