That will either be the IP address of the unit itself, the SLIP
interface or the serial console port. It depends on the software
version/modules you have installed.

Assuming you have access to a MIB browser (or just plain old snmpwalk
on UNIX) try looking for the following OID section:

[graeme at mrtg] snmpwalk **** publicinterfaces.ifTable.ifEntry.ifDescr

interfaces.ifTable.ifEntry.ifDescr.1 = "3Com Switch"
interfaces.ifTable.ifEntry.ifDescr.2 = "3Com Switch  type:SLIP"
interfaces.ifTable.ifEntry.ifDescr.101 = "RMON:10/100 Port 1"
interfaces.ifTable.ifEntry.ifDescr.102 = "RMON:10/100 Port 2"
interfaces.ifTable.ifEntry.ifDescr.103 = "RMON:10/100 Port 3"
interfaces.ifTable.ifEntry.ifDescr.104 = "RMON:10/100 Port 4"
interfaces.ifTable.ifEntry.ifDescr.105 = "RMON:10/100 Port 5"
interfaces.ifTable.ifEntry.ifDescr.106 = "RMON:10/100 Port 6"
interfaces.ifTable.ifEntry.ifDescr.107 = "RMON:10/100 Port 7"
interfaces.ifTable.ifEntry.ifDescr.108 = "RMON:10/100 Port 8"
interfaces.ifTable.ifEntry.ifDescr.109 = "RMON:10/100 Port 9"
interfaces.ifTable.ifEntry.ifDescr.110 = "RMON:10/100 Port 10"
interfaces.ifTable.ifEntry.ifDescr.111 = "RMON:10/100 Port 11"
interfaces.ifTable.ifEntry.ifDescr.112 = "RMON:10/100 Port 12"
interfaces.ifTable.ifEntry.ifDescr.113 = "ATM Port 13, ATM"

You should get something similar. Plus the descriptions should also be
reported by cfgmaker anyway...
