Loop-back Detection Global Settings

The Loop-back Detection function is used to
identify loops occurring between the Switch and a
device that is directly connected to it. This process
is accomplished by the use of a Configuration
Testing Protocol (CTP) packet that is generated by
the switch. Users may set the dispatching time
interval of the CTP packet and once a CTP packet
has returned to the port from where it originated, the
loop-back detection function will disable this port
until the anomaly has ceased, and the loop-back
occurrence will be noted in the Switch's log. Once
the loop-back problem has stopped, this port will be
automatically recovered in a time period that can
also be specified by the user.
