l If the destination node is a MEP, either mac mac-address or remote-mep mep-id mep-id
l If the destination node is a MIP, select mac mac-address.
l If the forwarding entry of the destination node does not exist in the MAC address table,
The intermediate device on the link to be tested only forwards LTMs and LTRs. In this manner,
the MD, MA, or MEP are not required to be configured on the intermediate device.

4.11.3 (Optional) Implementing Gmac trace

By performing the GMAC trace, you can detect connectivity between devices and locate faults.
Context
You need to configure the switchs at both ends and the intermediate switch on the link to be
tested.
Procedure
Step 1 Configuring the switchs at both Ends and the Intermediate switch
Do as follows on the switchs at both ends and the intermediate switch on the link to be tested:
1.
2.
Step 2 Implementing Gmac trace
Do as follows on the switch at one end of the link to be tested:
1.
2.

can be selected. If remote-mep mep-id mep-id is selected, the RMEP must already be created
with the remote-mep command.
interface interface-type interface-number must be specified.
Run:
system-view
The system view is displayed.
Run:
trace mac enable
Gmac trace is enabled globally.
By default, Gmac trace is disabled.
The following can be performed only after Gmac trace is enabled:
l Gmac trace can be implemented on the switch.
l The switchs can respond to LTMs of Gmac trace.
Run:
system-view
The system view is displayed.
Run:
trace mac mac-address vlan vlan-id [ interface interface-type interface-
number | -t timeout ] *
The connectivity fault between the switch and the remote switch is located.
