Yes, .iso.org.dod.internet.mgmt.mib-2.at.atTable.atEntry.atPhysAddress will do what you want. ================= That works but the mib entry is depricated. The entry they want you to use instead is: Directory: ~ip/ipNetToMediaTable/ipNetToMediaEntry/ipNetToMediaPhysAddress OID: 220.127.116.11.18.104.22.168.1.2 The "at" entry was put in the MIB with the implicit assumption that no protocol other than IP would ever use ARP. That's why something different was needed. Where $router is the IP address or name of the router, $comname is the community string (often public) and $querytype is "ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaPhysAddress" snmpwalk $router $comname $querytype e.g. snmpwalk 192.168.1.1 "public" "ip.ipNetToMediaTable.ipNetToMediaEntry.ipNetToMediaPhysAddress" supports both. Other router vendors do not.
