Configuring 40-Gigabit Interface Speed - Cisco Nexus 3548 Configuration Manual

Configuring Layer 2 Interfaces
Example
This example shows how to set the speed for a 1-Gigabit Ethernet port:
switch# configure terminal
switch(config)# interface ethernet 1/4
switch(config-if)# speed 1000

Configuring 40-Gigabit Interface Speed

Before you begin
To achieve 40-Gbps port speed, each of the four ports in an adjacent port group must have a 10-Gbps SFP
installed. All four SFP+ must be capable of 10-Gbps speed and must be the same type of port. By default, all
ports are 10-Gbps ports.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# interface type slot/port-range
3. switch(config-if-rang)# shut
4. switch(config-if-rang)# exit
5. switch(config-if)# interface type slot/port
6. switch(config-if)# speed 40000
7. switch(config-if)# no shut
DETAILED STEPS
Command or Action
Step 1 switch# configure terminal
Step 2
switch(config)# interface type slot/port-range
Step 3
switch(config-if-rang)# shut
Step 4 switch(config-if-rang)# exit
Step 5 switch(config-if)# interface type slot/port
Step 6 switch(config-if)# speed 40000
Step 7 switch(config-if)# no shut
Purpose
Enters global configuration mode.
Enters interface configuration mode for the specified range
of interfaces.
Shuts down the range of interfaces that you specified.
Exits the current configuration mode.
Enters interface configuration mode for the interface. You
specify the first port in the four adjacent port group to
configure that port with 40-Gbps speed. For example, you
specify interface 1/1, which is the first port in port group
1/1 through 1/4, to configure that port with 40-Gbps speed.
Note
Sets the speed on the interface for 40 Gbps.
Brings up the range of interfaces.
