ethoam linktrace
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]
Syntax Definitions
mac_address Target MAC address to be transmitted.
tar_mep_id Specifies the MEP for which the Loopback message is targeted.
src_mep_id Specifies the MEP that transmits the Loopback message. The valid
range is 1–8191.
domain_name Specifies the domain name. For more information on the different
formats of the domain name, refer to ethoam domain command on
page 25-3.
domain mac_address Specifies the CFM system MAC address.
association_name Name of the Ethernet OAM Association. Up to 48 (minus the domain
name length) characters may be used.
fdbonly Specifies that only the MAC addresses learned in a bridge's active data
forwarding table will be used to decide the egress port.
hop_count 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.
