With IPHost Network Monitor you can run simple snmp requests against a Nortel device in your network.
appnDlciVcDuplicatesFromSubnet
appn Dlci Vc Duplicates From Subnet
This attribute displays the number of subnet packets discarded due to duplication. Although packets are not retransmitted by the Frame Relay Vc, it is possible for the subnet to retransmit packets. When packets are out-of-sequenced and copies of the same packets arrive, then this attribute is increased.
