Field Descri
p
tion
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.

Usage guidelines
These LTR messages received as responses to automatically sent LTMs are stored in the buffer after you
executed the cfd linktrace auto-detection command.
With the size keyword not specified, this command displays the information of all LTRs stored in the
buffer.
