Description
Use the pause-protection command to enable/disable pause frame protection
mechanism.
Pause frame protection mechanism is disabled by default.
Pause frames, which can be utilized as packets to attack a network, are used in traffic
controlling. A switch that has pause frame protection mechanism enabled discards the
detected pause frames that are utilized to attack the network it resides and logs these
attacks in the logbuffer. If the switch experiences successive pause frame attacks, it
sends messages to the console to warn users.

Only A type cards support pause frame protection mechanism and the related
commands. A type cards include: LS81FT48A, LS81FM24A, LS81FS24A,
