Technical Note: How to change interface speed and duplex on 'switch mode'

[lsilva1]

Description

This article shows how to change the speed and duplex for individual interfaces under switch mode.

Solution

# config system virtual-switch
(virtual-switch) # edit internal
(internal) # config port
(port) # edit internal1
(internal1) # show full-configuration
config port
    edit "internal1"
        set speed auto
        set status up
        set alias ''
    next
end
(internal1) # set speed
auto        Automatically adjust speed.
10full      10M full-duplex.
10half      10M half-duplex.
100full     100M full-duplex.
100half     100M half-duplex.
1000full    1000M full-duplex.

(internal1) # set speed 100full
(internal1) # end
(internal) # end
#

After changing the speed and duplex, the status of the interface can be checked by using the command “diagnose hardware deviceinfo nic [interface]” as shown below:

# diagnose hardware deviceinfo nic internal1
