ma-name: Name of an MA, a character string of 1 to 43 characters. IEEE 802.1ag standard version
allows an MA name to contain letters, numbers, and special characters such as tilde (~), exclamation
mark (!), at sign (@), number sign (#), dollar sign ($), percent (%), caret (^), ampersand (&), asterisk(*),
brackets ({ }, ( ),[ ], < >), hyphen (-), underscore (_), plus (+), equal sign (=), vertical bar (|), backslash
(\), colon (:), semicolon (;), quotation marks (", '), comma (,), period (.), and slash (/). IEEE 802.1ag
draft5.2 version and IEEE 802.1ag draft5.2 interim version allow an MA name to contain letters,
numbers, and special characters such as hyphen (–) and underscore (_), but do not allow an MA name
to start or end with a special character.

Description
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.
•
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.
