Loopback Detection
This feature is used to temporarily shutdown a port on the Switch when a CTP (Configuration Testing Protocol) packet has been
looped back to the switch. When the Switch detects CTP packets are received from a port or a VLAN, it signifies a loop on the
network. The Switch will automatically block the port or the VLAN and send an alert to the administrator. The Loopback
Detection port will restart (change to discarding state) when the Loopback Detection Recover Time times out. The Loopback
Detection function can be implemented on a range of ports at a time. The user may enable or disable this function using the pull-
down menu. To view this window click, Configuration > Loopback Detection.
