LABEL DESCRIPTION

Active Select this option to enable loop guard on the Switch.

The Switch generates syslog, internal log messages as well as SNMP traps when it shuts

down a port via the loop guard feature.

Port This field displays a port number.

* Use this row to make the setting the same for all ports. Use this row first and then make

adjustments on a port-by-port basis.

Note: Changes in this row are copied to all the ports as soon as you make them.

Active Select this check box to enable the loop guard feature on this port. The Switch sends probe

packets from this port to check if the Switch it is connected to is in loop state. If the Switch

that this port is connected is in loop state the Switch will shut down this port.

Clear this check box to disable the loop guard feature.
