The number value must be in the range 10 through 1440 (10 minutes through 24 hours). The
default value is 0, indicating that the port is not automatically re-enabled.
Setting interface parameters on a port
Perform this procedure for every port you want to be monitored by ELD.
1. Log in to any switch in a Brocade VCS Fabric cluster.
2. In global configuration mode, enter the interface command to select the rbridge-id/slot/port for
which you want to enable edge-loop detection.
3. In 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. Enter the edge-loop-detection port-priority command to specify the ELD port priority of the
specified port for the selected VLAN. However, enabling switching is not mandatory for assigning a
port-priority.
NOTE
The priority range of values is from 0 through 255. A port with priority 0 means that shutdown for
this port is disabled. The default value port priority is 128
Setting the ELD port priority on two port/VLAN pairs
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.
switch(config)# interface TenGigabitEthernet 1/0/7
switch(conf-if-te-1/0/7)# edge-loop-detection vlan 10
switch(conf-if-te-1/0/7)# edge-loop-detection port-priority 5
switch(conf-if-te-1/0/7)# top
switch(config)# interface TenGigabitEthernet 4/0/6
switch(conf-if-te-1/0/7)# edge-loop-detection vlan 10
switch(conf-if-te-1/0/7)# edge-loop-detection port-priority 7
Troubleshooting edge-loop detection
Use the edge-loop detection commands to view and correct misconfigurations
1. Log in to any switch in a Brocade VCS Fabric cluster.
2. In the global configuration mode, enter the show edge-loop-detection command to display edge-
loop detection statistics for the Brocade VCS Fabric cluster.
The command output shows ports disabled by ELD.
3. Correct any misconfigurations detected in step 2.
4. Perform one of the following operations in global configuration mode:
• To re-enable a single port disabled by ELD:
1. Enter the shutdown command on the port.
2. Enter the no shutdown command on the port.
