Uplink Failure Detection configuration
Uplink Failure Detection (UFD) supports network fault tolerance in network adapter teams. Use these
commands to configure 4 Failure Detection Pair of one Links to Monitor (LtM) group and one Links to
Disable (LtD) group. When UFD is enabled and a Failure Detection Pair is configured, the switch
automatically disables ports in the LtD if it detects a failure in the LtM. The failure conditions which are
monitored in the LtM group include port link state moving to down, or port state moving to Blocking if
Spanning Tree Protocol is enabled.
The following table describes the Uplink Failure Detection (UFD) Configuration commands.
