This section describes how to configure the auto-negotiation mode.


Procedure

Step1          Enable auto-negotiation mode.

    set interface gigabit-ethernet<interface-name> speed auto

NOTE:

Only the 10G, 5G/2.5G and 1G RJ45 ports support auto-negotiation mode and to set auto-negotiation rate.

Step2         Configure the auto-negotiation rate of Ethernet interfaces in auto-negotiation mode.

                   set interface gigabit-ethernet <interface-name> auto-speeds <auto-speed>

Configuration Example

Step1         Enable auto-negotiation mode.

admin@Xorplus# set interface gigabit-ethernet ge-1/1/1 speed auto


NOTE:

Only the 10G, 5G/2.5G and 1G RJ45 ports support auto-negotiation mode and to set auto-negotiation rate.

Step2         Configure the auto-negotiation rate of ge-1/1/1.

admin@Xorplus# set interface gigabit-ethernet ge-1/1/1 auto-speeds 100
admin@Xorplus# set interface gigabit-ethernet ge-1/1/1 auto-speeds 10

Verify the Configuration

  •    Use run show interface gigabit-ethernet ge-1/1/1 command to view the current interface status information of ge-1/1/1 interface. Check the Speed and Auto-negotiation field in the command output. 
admin@XorPlus# run show interface gigabit-ethernet ge-1/1/1
