3.34 The Tellabs 7300 NEs provide the following 802.1ag Ethernet connectivity
and fault management support. Refer to Table 3.8, page 2-22.
3.35 The 10G Switch module in the Tellabs 7345 Switch and the 1G Edge
Switch Module in the Tellabs 7325 Switch support 802.1ag and the following
functionality:
• Continuity Check Message for fault detection between MEPs
(Maintenance End Points) and for discovery of other MEPs.
• Link Trace (Message and Reply) for fault isolation and path discovery
by tracing the path towards a MAC address.
• Loopback (Message and Reply): both unicast (LTR) between a pair of
MEPs and multicast (LTM).
3.36 For activating OAM, Ethernet CFM functions are enabled on the Tellabs
7345 Switch and the Tellabs 7325 Switch by provisioning the appropriate
maintenance points.
Maintenance Domain (MD) 3.37 An MD is created by provisioning the domain name and the level at which
the MD is defined. Unique priorities may be provisioned for the frames carrying
CCM/LTM messages and LBM messages.
Maintenance Association
(MA)
3.38 An MA is created by identifying the MA ID and either the primary VLAN that
is part of the MA or “unaware” for an MA that monitors all frames passing through
a port regardless of VLAN. Multiple VLANs may be provisioned to be associated
with a primary VLAN.
Maintenance Association
End Point (MEP)
3.39 An MEP is created by defining the level, direction, MEP ID, and the primary
VLAN (or VLAN unaware). In addition, the intervals for continuity check messaging
may be provisioned, and the priority to use for continuity check messages and
loopback messages may be set. Continuity check messages can be configured for
1 second, 10 seconds, 1 minute, and 10 minutes.
