Table 1-4 display cfd linktrace-reply command output description
Field Description
Service instance Service instance to which the MEPs that send LTMs belong
MEP ID ID of the MEP that sends LTMs
MAC Address Source MAC address in the LTR message
TTL Hop count when LTM passes the device
Last MAC MAC address of the last-hop device the LTM passes
Forwarded
z Yes means that the device has forwarded the LTMs.
z No means that the device did not forward the LTMs.
Relay Action
Indicates whether the forwarding device found the destination MAC address in its
MAC address table.
When the standard version of IEEE 802.1ag is used:
z Hit: Indicates that the current device is the destination device.
z FDB: Indicates that the forwarding device found the destination MAC address.
z MPDB: Indicates that the destination MAC address is not found, or that the
destination MAC address is found in the MEP or MIP database.
When IEEE 802.1ag draft5.2 or the IEEE 802.1ag draft5.2 interim version is used:
z Found: Indicates that the forwarding device found the destination MAC address
in its MAC address table.
z Unknown: Indicates that the forwarding device failed to find the destination MAC
address in its MAC address table.
z None: Indicates that it is a MEP that responded to the LTM message. A MEP
does not need to find the destination MAC address.
