Command History
Usage Guidelines
The first 8 ports of a Cisco Nexus 5010 switch and the first 16 ports of a Cisco Nexus 5020 switch are
switchable 1-Gigabit and 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 and then
set its speed with the speed command.
Note
If the interface and transceiver speed is mismatched, the SFP validation failed message is displayed when
you enter the

/[

port
command. For example, if you insert a
1-Gigabit SFP transceiver into a port without configuring the
speed 1000
command, you will get this
error.
By default, all ports on a Cisco Nexus device are 10 Gigabits.
