Table 89 Advanced Application > Loop Guard
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.
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.
