Nortel Networks 3500, NTRN10AN manual Supported on 2xGigE/FC-P2P

Operation, administration, and maintenance (OAM) features 2-91

The 2xGigE/FC-P2P circuit packs collects Generic Interface Operational Measurements (Generic Interface OMs) which contain a set of counters not specific to any interface type. It is also used for the WAN side of the card. It consists of 64 bit octet and packet counters for all interface speeds. The counters are combined for unicast, multicast, and broadcast packets.

Table 2-16 on page 2-91defines the generic interface Operational Measurements (OM) for LAN interface supported on 2xGigE/FC-P2P circuit packs.

Table 2-17 on page 2-92defines the generic interface Operational Measurements (OM) for WAN interface supported on 2xGigE/FC-P2P circuit pack.

Note: Dribble bit errors are not counted.
