11.6.6 Linktrace Procedures

A Linktrace Message (LTM) is initiated by a MEP to trace a path to a target MAC address or MEP
ID. It is forwarded from MIP to MIP, up to the point at which the LTM reaches its target, a MEP, or
can no longer be forwarded. Each MEP or MIP along the path to the target generates a linktrace
reply (LTR).

11.6.6.2 Initiating a Linktrace Request

You can initiate a link trace and monitor the results on a separate screen.

NOTE: Only one Linktrace session can be active at a time for the entire system.

1. On the Maintenance End Point Attributes screen (Figure 11-22 for 802.1ag or Figure 11-

22 for Y.1731), type T and press Enter. If a linktrace request was already initiated from
this MEP, the Linktrace Monitoring screen (Figure 11-27) opens. Otherwise, the Linktrace
Request screen (3.) opens.

2. To enter a Destination address for the linktrace request, type 1 and press Enter. Select

MAC address or MEP ID and press Enter. You are prompted to type the address or ID.
Type a MAC address or MEP ID and press Enter.

3. To set the FDB only flag, type 2 and press Enter. If the FDB only flag is set to Yes, the

linktrace response is sent to the originator only if the egress port for the destination MAC
address is known by the forwarding database and not through other methods. Select Yes
or No and press Enter.
