Configuring UFD

Figure 10-1shows a basic UFD configuration. In this example, NIC 1 is the primary network adapter; NIC 2 is a non-primary adapter. NIC 1 is connected to port 16 and NIC 2 is connected to port 17. Port 2 is connected to a Layer 2/3 routing switch.

The following procedure pertains to the example shown in Figure 10-1.

1.Configure Network Adapter Teaming on the servers.

2.Assign the Link to Monitor (LtM) ports.

RS G8000 (config)# ufd fdp ltm port 2

3.Assign the Link to Disable (LtD) ports.

RS G8000 (config)# ufd fdp ltd port 16

4.Turn on Uplink Failure Detection (UFD).

RS G8000 (config)# ufd fdp enable

RS G8000 (config)# ufd enable

Monitoring UFD

The UFD information menu displays the current status of the LtM and LtD, and their member ports or trunks. For example:

RS G8000# show ufd
