Use the drop-down menu to enable or disable loopback detection. The default is
Disabled.
None – The trap will not be sent in any situation.
Loop Detected – The trap is sent when the loop condition is detected.
Loop Cleared – The trap is sent when the loop condition is cleared.
Both – The trap will be sent for both conditions.
Set a Loopdetect Interval between 1 and 32767 seconds. The default is 10 seconds.
Time allowed (in seconds) for recovery when a Loopback is detected. The Loopdetect
Recover Time can be set at 0 seconds, or 60 to 1000000 seconds. Entering 0 will
disable the Loopdetect Recover Time. The default is 60 seconds.
Select the mode you wish to use either Port Based or VLAN Based.
Port Based – This mode can detect loopback based on the Port. If the Switch detects
loopback on the Port, the loopback detection will only block the traffic which belongs
to this Port. Other VLAN traffic should not be affected by this.
VLAN Based – This mode can detect loopback based on the VLAN. If the Switch
detects loopback on the VLAN, the loopback detection will only block the traffic which
belongs to this VLAN. Other VLAN traffic should not be affected by this. Loopback
detection will send the CPT packets periodically per port per VLAN in VLAN based
mode.
Select the unit you wish to configure.
Use the drop-down menu to select a port or range of ports to be configured.
