To use the normal UDLD mode, you must configure one of the ports for normal mode and configure the
other port for the normal or aggressive mode. To use the aggressive UDLD mode, you must configure
both ports for the aggressive mode.
Note Before you begin UDLD must be enabled for the other linked port and its device.

Configuring Interface Speed

The first eight ports of a Nexus 5010 switch and the first 16 ports of a Nexus 5020 switch are switchable
1-Gigabit/10-Gigabit ports. The default interface speed is 10-Gigabit. To configure these ports for
1-Gigabit Ethernet, insert a 1-Gigabit Ethernet SFP transceiver into the applicable port then set its speed
with the speed command.
