With IPHost Network Monitor you can run simple snmp requests against a Cisco device in your network.
frCircuitLogicalIfIndex
fr Circuit Logical If Index
1.3.6.1.2.1.10.32.2.1.20
Normally the same value as frDlcmiIfIndex, but different when an implementation associates a virtual ifEntry with a DLC or set of DLCs in order to associate higher layer objects such as the ipAddrEntry with a subset of the virtual circuits on a Frame Relay interface. The type of such ifEntries is defined by the higher layer object; for example, if PPP/Frame Relay is implemented, the ifType of this ifEntry would be PPP. If it is not so defined, as would be the case with an ipAddrEntry, it should be of type Other.
