It is possible to define the repetition time of the packet and the time that a given port
will remain off if a loop is detected. Besides, each port can be freely set to have the
function enabled and send or not loop detection packets. If a loop is detected, there
are three actions allowed:

Shutdown port;

Shutdown and log;

Log only.
If the Log option is enabled, a log server must be configured to send the log
messages informing the loop detection of a given port must be set.
