snmp mac address and if index query
i normally query for all arp entries using the RFC1213-MIB mib and ipNetToMediaPhysAddress or ipNetToPhysicalPhysAddress oid; the typical output is something like: IP-MIB::ipNetToPhysicalPhysAddress.13.ipv4."172.18.x.y" = STRING: 0:d0:ff:ee:fc:a IP-MIB::ipNetToPhysicalPhysAddress.14.ipv4."127.2.0.1" = STRING: 0:23:e9:6e:97:0 IP-MIB::ipNetToPhysicalPhysAddress.17.ipv4."127.1.1.2" = STRING: 0:1:23:45:67:0 IP-MIB::ipNetToPhysicalPhysAddress.17.ipv4."127.1.1.3" = STRING: 0:1:23:45:67:1 IP-MIB::ipNetToPhysicalPhysAddress.17.ipv4."127.1.1.4" = STRING: 0:1:23:45:67:2 IP-MIB::ipNetToPhysicalPhysAddress.17.ipv4."127.1.1.5" = STRING: 0:1:23:45:67:3 IP-MIB::ipNetToPhysicalPhysAddress.19.ipv4."a.b.c.d" = STRING: 0:0:c:7:ac:97 (first an last ip's redacted) the number before the ipv4 bit usually corresponds to the ifIndex of the interface that the arp was seen on. however, on our ltm box: IF-MIB::ifIndex.80 = INTEGER: 80 IF-MIB::ifIndex.736 = INTEGER: 736 IF-MIB::ifIndex.752 = INTEGER: 752 IF-MIB::ifIndex.768 = INTEGER: 768 IF-MIB::ifIndex.784 = INTEGER: 784 IF-MIB::ifIndex.800 = INTEGER: 800 IF-MIB::ifIndex.816 = INTEGER: 816 IF-MIB::ifIndex.832 = INTEGER: 832 IF-MIB::ifIndex.848 = INTEGER: 848 IF-MIB::ifIndex.864 = INTEGER: 864 IF-MIB::ifIndex.880 = INTEGER: 880 IF-MIB::ifIndex.896 = INTEGER: 896 IF-MIB::ifIndex.912 = INTEGER: 912 IF-MIB::ifIndex.928 = INTEGER: 928 (as you can see the index's don't match). how can i match the ifIndex value from ipNetToPhysicalPhysAddress to a real physical description like that presented with sysInterfaceName ?
