Table 12 Command output
Field Descri
p
tion
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
Indicates whether the device forwards LTMs:
• Yes—The device has forwarded the LTMs.
• No—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 (IEEE 802.1ag) of CFD is used:
• Hit—The current device is the destination device.
• FDB—The forwarding device found the destination MAC address.
• MPDB—The destination MAC address is not found, or the destination MAC
address is found in the MEP or MIP database.
When the IEEE 802.1ag draft5.2 version or the IEEE 802.1ag draft5.2 interim
version of CFD is used:
• Found—The forwarding device found the destination MAC address in its MAC
address table.
• Unknown—The forwarding device failed to find the destination MAC address in
its MAC address table.
• None—It is a MEP that responded to the LTM message. A MEP does not need to
find the destination MAC address.
