Configuring UFD on Switch 2 (AOS CLI example)
1.
Create a trunk group of uplink ports (20-24) to monitor. First you must set each port to full duplex mode.
>> Main# /cfg/port 20/gig/mode full
>> Main# /cfg/port 22/gig/mode full
>> Main# /cfg/trunk 2
>> Trunk group 2# ena
>> Trunk group 2# add 20
>> Trunk group 2# add 22
2.
Assign the trunk group to be monitored for communication failure.
>> Main# /cfg/ufd/fdp 1/ena
>> FDP# ltm
>> Failover Link to Monitor# addtrnk 2
3.
Assign downlink ports (1-16) to disable when an uplink failure occurs.
>> Main# /cfg/ufd/fdp 1/ltd
>> Failover Link to Disable# addport 1
>> Failover Link to Disable# addport 2
4.
Turn UFD on.
>> Main# /cfg/ufd/on
>> Uplink Failure Detection# apply (Make your changes active)
>> Uplink Failure Detection# save
When a link failure or Spanning Tree blocking occurs on trunk group 2, Switch 2 disables port 1 and port 2.
