1. Log in to any switch in a Brocade VCS Fabric cluster.

2. In the global configuration mode, enter the interface command to select the RBridge/slot/port 

for which you want to enable edge-loop detection.

3. In the interface configuration mode, enter the edge-loop-detection vlan command to specify 

the VLAN you want ELD to monitor on this port.

If you do not specify a VLAN, the command fails.

4. Optional: Enter the edge-loop-detection port-priority command to specify the ELD port priority 

of the specified port for the selected VLAN. Enabling switching is not mandatory when 
assigning a port-priority.

Example 

This example sets the ELD port priority on two port/VLAN pairs: port 1/0/7 VLAN 10 and port 
4/0/6 VLAN 10. If both these ports are detected in the same loop, ELD shuts down port 4/0/6 
when the pdu-rx-limit for the Brocade VCS Fabric cluster is reached. Port 4/0/6 is chosen for shut 
down because it has been assigned the lower priority (higher number) then port 1/0/7.

(config)# interface TenGigabitEthernet  1/0/7 

(conf-if-te-1/0/7)# edge-loop-detection vlan 10 

(conf-if-te-1/0/7)# edge-loop-detection port-priority 5 

(conf-if-te-1/0/7)# top 

(config)# interface TenGigabitEthernet 4/0/6 

(conf-if-te-1/0/7)# edge-loop-detection vlan 10 

(conf-if-te-1/0/7)# edge-loop-detection port-priority 7
