Description
Linktrace to target MEP 2001 with the sequence number 1101-43361.
Source MAC address in the LTR messages.
Hop count when the LTM passes the device.
MAC address of the last-hop device the LTM passes.
Indicates whether the device forwards LTMs:
•
Yes—The current device forwards LTMs.
•
No—The current device does not forward LTMs.
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 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.
