'28.182.27.202' looks like an ip address to me Close. It's actually 0:0:28:182:27:202, and is the Mac Address of the system concerned. This OID translates to BRIDGE-MIB::dot1dTpFdbAddress.0.0.28.182.27.202 and is the index of the Forwarding Database (dot1dTpFdbTable) BRIDGE-MIB::dot1dTpFdbPort (mib-2.17.4.3.1.2) will report which port traffic for that particular Mac Address will be sent to. You'd need to use another lookup to perform the Mac<->IP mapping (e.g. the ipNetToMediaTable of some well-connected system, probably *not* the switch itself). Or use a local database. > I don't know of any stanard MIBs that have ip/host mapping. That would be the DISMAN-NSLOOKUP-MIB. It's not particularly widely implemented, AFAIK.
