    speed (auto-negotiation | speed);

    Hierarchy Level

    [edit interfaces interface-name ether-options]

    Release Information

    Statement introduced in Junos OS Release 11.1 for the QFX Series.

    Description

    Configure the speed of the interface.

    Default

    Autonegotiation is automatically enabled for Gigabit Ethernet interfaces. Autonegotation is not an option for 10-Gigabit Ethernet interfaces. No explicit action is taken after the autonegotiation is complete or if the negotiation fails. If the autonegotiation statement at the [edit interfaces interface-name ether-options] hierarchy level is enabled, the auto-negotiation option is enabled by default.

    Options

    • auto-negotiation—Automatically negotiate the speed based on the speed of the other end of the link. Autonegotiation is automatically enabled for Gigabit Ethernet interfaces. Autonegotation is not an option for 10-Gigabit Ethernet interfaces. No explicit action is taken after the autonegotiation is complete or if the negotiation fails.
    • speed —Specify the interface speed. This value sets the speed that is used on the link. If the auto-negotiation statement is enabled on a Gigabit Ethernet interface, configure the value to advertise to the interface at the other end of the link. If you disable autonegotation on a Gigabit Ethernet interface, you must explicitly configure the speed to 1g.
