Configuring UFD on Switch 1 (CLI example)
1. Assign uplink ports (18-21) to be monitored for communication failure.
>> Main# /cfg/ufd/fdp ena (Enable Failure Detection Pair)
>> FDP# ltm (Select Link to Monitor menu)
>> Failure Link to Monitor# addport 19 (Monitor uplink port 19)
2. Assign downlink ports (1-16) to disable when an uplink failure occurs.
>> /cfg/ufd/fdp/ltd (Select Link to Disable menu)
>> Failure Link to Disable# addport 1 (Add port 1 as a Link to Disable)
>> Failure Link to Disable# addport 2 (Add port 2 as a Link to Disable)
3. Turn UFD on.
>> /cfg/ufd/on (Turn Uplink Failure Detection on)
>> Uplink Failure Detection# apply (Make your changes active)
>> Uplink Failure Detection# save (Save for restore after reboot)
When a link failure or Spanning Tree blocking occurs on port 19, Blade Switch 1 disables port 1 and
port 2.
Configuring UFD on Switch 2 (CLI example)
1. Create a trunk group of uplink ports (18-21) to monitor.
>> Main# /cfg/trunk 2 (Create trunk group 2)
>> Trunk group 2# ena (Enable trunk group 2)
>> Trunk group 2# add 18 (Add port 18 to trunk group 2)
>> Trunk group 2# add 19 (Add port 19 to trunk group 2)
2. Assign the trunk group to be monitored for communication failure.
>> Main# /cfg/ufd/fdp ena (Enable Failover Pair)
>> FDP# ltm (Select Link to Monitor menu)
>> Failover Link to Monitor# addtrnk 2 (Monitor trunk group 2)
3. Assign downlink ports (1-16) to disable when an uplink failure occurs.
>> Main# /cfg/ufd/fdp/ltd (Select Link to Disable menu)
>> Failover Link to Disable# addport 1 (Add port 1 as a Link to Disable)
>> Failover Link to Disable# addport 2 (Add port 2 as a Link to Disable)
4. Turn UFD on.
>> Main# /cfg/ufd/on (Turn Uplink Failure Detection on)
>> Uplink Failure Detection# apply (Make your changes active)

When a link failure or Spanning Tree blocking occurs on trunk group 2, Blade Switch 2 disables port 1
and port 2.
