Table 8 Command output Field Description Linktrace to MEP 2001 with the sequence number Linktrace to target MEP 2001 with the sequence number 1101-43361. 1101-43361 MAC Address Source MAC address in the LTR messages. TTL Hop count when the LTM passes the device. Last MAC MAC address of the last-hop device the LTM passes. Forwarded Indicates whether the device forwards LTMs: • Yes means that the current device forwards LTMs. • No means that the current device does not forward 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 that 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 draft 5.2 interim version of CFD is used: • Found-The forwarding device found the destination MAC address. • Unknown-The forwarding device failed to find the destination MAC address. • None-It is a MEP that responded to the LTM message. A MEP does not need to find the destination MAC address. cfd linktrace auto-detection Syntax cfd linktrace auto-detection [ size size-value ] View undo cfd linktrace auto-detection System view Default level 2: System level 22

Description
Linktrace to MEP 2001
with the sequence number
1101-43361
Linktrace to target MEP 2001 with the sequence number 1101-43361.
MAC Address
Source MAC address in the LTR messages.
TTL
Hop count when the LTM passes the device.
Last MAC
MAC address of the last-hop device the LTM passes.
Forwarded
Indicates whether the device forwards LTMs:
•
Yes means that the current device forwards LTMs.
•
No means that the current device does not forward 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 that 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 draft 5.2 interim
version of CFD is used:
•
Found
—The forwarding device found the destination MAC address.
•
Unknown
—The forwarding device failed to find the destination MAC address.
•
None
—It is a MEP that responded to the LTM message. A MEP does not need
to find the destination MAC address.
