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 the port number. * means all ports.
*
Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings 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.
