2-70Operation, administration, and maintenance (OAM) features

When connecting to OCn circuit packs, the following protection schemes supported by the OCn circuit pack can be used.

UPSR: 2WAY (unprotected), 2WAYPR, 1WAY (unprotected), 1WAYPR

1+1 linear: 1WAY, 2WAY

Note: 1WAY protection schemes support another 1WAY connection to travel back from the same circuit pack.

BLSR: 2WAY (protected), 2WAYPR(for interconnecting BLSR or UPSR rings)

OAMP support

Similar to traditional TDM service, the following features are supported:

Connection Identifier (CID) is supported.

STS1 and STS3c path trace are supported.

Ethernet Operational Measurements

The Ethernet Operational Measurements collected by the 2x100BT-P2P circuit packs can be divided into two groups: Generic Interface Operational Measurements (based on the Interfaces Group MIB, RFC 1213, RFC 2233, RFC 2863) and Ethernet Specific Operational Measurements (based on RFC 2665 Ethernet-Like MIB).

The 2x100BT-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 the 2x100BT-P2P a circuit pack.

Table 2-17 on page 2-92defines the generic interface Operational Measurements (OM) for WAN interface supported on the 2x100BT-P2P circuit packs.

Table 2-18 on page 2-93defines the Ethernet specific Operational Measurements (OM) supported by the 2x100BT-P2P circuit packs

Note: Dribble bit errors are not counted.

For a description of the 2x100BT-P2P circuit pack, see 2x100BT-P2P circuit pack on page 3-91.
