Use this page to create a manually controlled, customized loop detection beacon, then view its results.
Note: The loop detection diagnostic tool does not require an interface to be created in order to send a tunnel-level beacon.
To configure a customized loop detection beacon
Access the page Loop Detection ►Diagnostic Tool.
The Loop Detection Diagnostic Tool page opens.Use the information in the table below to configure the loop detection beacon, then click Send.
A loop detection beacon is transmitted from the specified port; Frame is successfully sent appears in the frame at the bottom of the page. If no loop is detected within the period specified timeout value, it will expire.To view the results of the loop detection beacon created in the previous step, click Show.
The frame at the bottom of the page refreshes with the loop detection beacon’s results.
Results similar to the following will appear:Beacon Type : LPDB
Status : Received
Port : PORT-4
Vlan1 Id : 100
Vlan1 Ethertype : T-VLAN
Vlan2 Id : 200
Vlan2 Ethertype : S-VLAN
Vlan3 Id : 300
Vlan3 Ethertype : C-VLAN
Timeout (s) : 3
Round trip time (usec) : 40
