With IPHost Network Monitor you can run simple snmp requests against a Cisco device in your network.
Cisco Ethernet Virtual Connection Evc Uni Id
This object indicates the string-value identifying the UNI that is in the EVC. For UNI that is local, this value is the same as cevcUniIdentifier for the same ifIndex value as cevcEvcLocalUniIfIndex. For UNI that is not on the system, this value may be derived from the underlying OAM protocol. If the UNI identifier value is not specified for the UNI or it is unknown, the value of the cevcEvcUniId column is a zero-length string.
