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 the port number.
* 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.
Apply Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to
save your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
