ipInterfaceMainRouterAddr
Module: CROUTE-MIB
OID (symbolic): CROUTE-MIB::ipInterfaceMainRouterAddr
OID (numeric): 1.3.6.1.4.1.81.31.1.2.1.9
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: The IP address of the main router backed up on this interface.
What is ipInterfaceMainRouterAddr?
This read-write IpAddress object specifies the IP address of the primary router that this interface is configured to back up, relevant when IP Redundancy is in use. An admin sets this on a standby interface so it knows which router's address to monitor and take over from if that router fails. For example, configuring ipInterfaceMainRouterAddr to point at the primary router's IP lets the standby unit detect an outage and assume that address once ipRedundancyTimeout expires.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.1.2.1.9 snmpwalk -v2c -c public <target> CROUTE-MIB::ipInterfaceMainRouterAddr
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.81.31.1.2.1.9.1 snmpget -v2c -c public <target> CROUTE-MIB::ipInterfaceMainRouterAddr.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.81.31.1.2.1.9.1 a <value>
