Configuring Uplink Failure Detection - HP GbE2c - Blc Layer 2/3 Fiber SFP Option Application Manual

Configuring Uplink Failure Detection

The preceding figure shows a basic UFD configuration. Port 21 on Blade Switch 1 is connected to a Layer 2/3
routing switch outside of the chassis. Port 20 and port 22 on Blade Switch 2 form a trunk that is connected to a
different Layer 2/3 routing switch. The interconnect ports (17-18) are disabled.
In this example, NIC 1 is the primary network adapter; NIC 2, NIC 3, and NIC 4 are non-primary adapters. NIC 1
and NIC 2 are connected to port 1 and port 2 on Blade Switch 1. NIC 3 and NIC 4 are connected to port 1 and
port 2 on Blade Switch 2.
Configuring UFD on Switch 1 (CLI example)
1. Assign uplink ports (20-24) to be monitored for communication failure.
>> Main# /cfg/ufd/fdp ena
>> FDP# ltm
>> Failure Link to Monitor# addport 21 (Monitor uplink port 21)
2. Assign downlink ports (1-16) to disable when an uplink failure occurs.
>> /cfg/ufd/fdp/ltd
>> Failure Link to Disable# addport 1
>> Failure Link to Disable# addport 2
3. Turn UFD on.
>> /cfg/ufd/on
>> Uplink Failure Detection# apply
>> Uplink Failure Detection# save
When a link failure or Spanning Tree blocking occurs on port 21, Switch 1 disables port 1 and port 2.
Configuring UFD on Switch 2 (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 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/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.
