Enables the maintenance entity to initiate transmitting Link Trace Messages (LTM). 

ethoam linktrace  {target-macaddress mac_address | target-endpoint tar_mep_id}  source-endpoint 
src_mep_id domain {domain_name | mac_address} association association_name [flag fdbonly] [hop-
count hop_count]

Target MAC address to be transmitted.

Specifies the MEP for which the Loopback message is targeted.

Specifies the MEP that transmits the Loopback message. The valid 
range is 1–8191.

Specifies the domain name. For more information on the different 
formats of the domain name, refer to 

domain mac_address

Specifies the CFM system MAC address.

Name of the Ethernet OAM Association. Up to 48 (minus the domain 
name length) characters may be used.

Specifies that only the MAC addresses learned in a bridge's active data 
forwarding table will be used to decide the egress port.

Indicates the number of hops remaining in this LTM. Each bridge that 
handles the LTM decreases the value by 1. This decreased value is 
returned to the LTM. The valid range is 1–2^32.
