We're in a catch 22, but a little history first. We're supporting a hotel that is using an IP3 NetAccess gateway to control guest Internet access. From my understanding, the IP3 gateway does an SNMP query to determine which port a particular MAC address is on, and the string I found from debugging SNMP on the switch is "dot1dTpFdbEntry.18.104.22.168.40.43.200", which I believe is also ".22.214.171.124.126.96.36.199.3.1. 188.8.131.52.40.43.200". This OID does not "live" on this switch, so we tried a spare 2948G with the IP3 and got the same results. IP3 was sued and is apparently out of business, and the Catalyst is running the latest version of firmware (I believe 12.2.50). We're under the gun to get this working, but I'm out of ideas, and unfortunately replacing the IP3 isn't an option at this point. Does anyone have ideas we could try?
