    redundant-port

    Syntax

    To specify a member interface with optional failover timeout and packet sampling settings:

    [ no ] redundant-port interfaceType interfaceSpecifier [ [ failover timeout
    failoverTime ] [ packet-sampling [ delay delayTime ] ] ]

    To specify a member interface with optional auto-reversion, transmitter, and failover timeout settings:

    [ no ] redundant-port interfaceType interfaceSpecifier [ [ auto-revert ] [ transmitter { on | off } ] [ failover timeout failoverTime ] ]

    Release Information

    Command introduced in JunosE Release 8.0.0.

    Description

    Specifies a member link of a LAG bundle as redundant. The no version disables the redundant status of the member link or disables the specified redundancy setting for the member link.

    Options

    • interfaceType—Interface type; see Interface Types and Specifiers
    • interfaceSpecifier—Particular interface; format varies according to interface type; see Interface Types and Specifiers
    • failoverTime—Time between the current link event leading to failover or reversion and the previous link failover or reversion, in the range 100-10000 milliseconds (ms). The default value is 1000 milliseconds.
    • packet-sampling—Enables packet sampling to determine a failed port. By default, packet sampling is disabled.
    • delayTime—Minimum time difference between redundant and active port samples, in the range 100–10000 milliseconds (ms). The default value is 0 millisecond.
    • auto-revert—Specifies that the failed port automatically resumes as active. By default, auto revert is disabled.
    • transmitter—Enable or disable the transmitter when in redundant mode
      • on—Enabling the transmitter provides for a quick LAG failover in the event one of the non-redundant links in the LAG fail. This is particularly true when LACP has been enabled on the LAG, because it can take several seconds for LACP to converge on a link
      • off—Disabling the transmitter enables the remote end of the redundant link to also be in the operational Down state, which might be a requirement for third-party equipment when supporting redundancy over LAG
