ipInterfaceProxyArp
Module: CROUTE-MIB
OID (symbolic): CROUTE-MIB::ipInterfaceProxyArp
OID (numeric): 1.3.6.1.4.1.81.31.1.2.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When proxy ARP is enabled, the router responds to ARP requests received on one link-layer interface for an IP-address that is reachable via another link-layer interface. The response provides the router's own MAC address.
What is ipInterfaceProxyArp?
This read-write enumerated integer turns Proxy ARP on or off for the interface, letting the router answer ARP requests on one interface for addresses actually reachable via another interface, replying with its own MAC address. An admin enables this to let hosts on a subnet reach addresses on another subnet as if they were local, without those hosts needing a correctly configured default gateway. For example, enabling proxy ARP lets a misconfigured host that lacks a gateway setting still reach another subnet because the router transparently answers ARP requests on its behalf.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.1.2.1.7 snmpwalk -v2c -c public <target> CROUTE-MIB::ipInterfaceProxyArp
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.81.31.1.2.1.7.1 snmpget -v2c -c public <target> CROUTE-MIB::ipInterfaceProxyArp.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.81.31.1.2.1.7.1 i <value>
