The set interface gigabit-ethernet auto-speeds command sets the auto-negotiation rate of an interface in auto-negotiation mode.

Command Syntax

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

Parameter

Parameter

Description

gigabit-ethernet <interface-name>

Specifies the interface name.

auto-speeds <auto-speed>

Specifies the auto-negotiation rate, the unit is Mbit/s.

For 1G RJ45port, the values of auto-negotiation rate could be 1000M, 100M or 10M.
For 10G RJ45 port, the values of auto-negotiation rate could be 10000M, 1000M or 100M.
For 5G/2.5G RJ45 port, the values of auto-negotiation rate could be 100M, 1000M, 2500M, 5000M and 10000M.

Usage Guidelines

NOTE:

Only the 10G, 5G/2.5G and 1G RJ45 ports support auto-negotiation mode and auto-negotiation rate.
The auto-negotiation rates configured on the interfaces must have an intersection at both ends of the link.

Run the set interface gigabit-ethernet<interface-name> speed auto command to configure the Ethernet interface to work in auto-negotiation mode before using the set interface gigabit-ethernet <interface-name> auto-speeds command to manually specify the auto-negotiation rate.

Only the 10G, 5G/2.5G and 1G RJ45 ports support auto-negotiation mode. By default, these interfaces work in auto-negotiation mode. In auto-negotiation mode the ports negotiate any rate supported by the two devices. If the negotiated interface rate is not the required value, you can use the set interface gigabit-ethernet <interface-name> auto-speeds command to manually specify the auto-negotiation rate to make the interface negotiate the rate within the specified range.

Example

Set the auto-negotiation rates of ge-1/1/1 interface to 100M and 10M.

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

Set the auto-negotiation rates of ge-1/1/1 interface to 1000M.

admin@Xorplus# set interface gigabit-ethernet ge-1/1/1 auto-speeds 1000
admin@Xorplus# set interface gigabit-ethernet ge-1/1/1 speed auto
