Configuring a Link Level Flow Control Watchdog Interval

Link Level Flow Control Watchdog (LLFCWD) is enabled globally by default. LLFCWD on an interface is
enabled automatically when PFC and PFCWD are configured on the interface. If an LLFC packet is seen on
a PFC/PFCWD configured interface that doesn't have LLFC configured, the LLFC watchdog is triggered.
PFCWD interval and PFCWD multiplier CLI commands are used to configure the LLFCWD interval and
multipliers. Use this procedure to configure the LLFC watchdog interval and the multiplier used to restore
the no-drop queue.
Note To disable the LLFC watchdog, enter the following in the global configuration mode:
switch(config)# link-level-flow-control watch-dog interval off
