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 (Enable Failure Detection Pair) >> FDP# ltm (Select Link to Monitor menu) >> 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 (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 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 (Set port 20 to full duplex) >> Main# /cfg/port 22/gig/mode full (Set port 22 to full duplex) >> Main# /cfg/trunk 2 (Create trunk group 2) >> Trunk group 2# ena (Enable trunk group 2) >> Trunk group 2# add 20 (Add port 20 to trunk group 2) >> Trunk group 2# add 22 (Add port 22 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) >> Uplink Failure Detection# save (Save for restore after reboot) When a link failure or Spanning Tree blocking occurs on trunk group 2, Switch 2 disables port 1 and port 2.
