# 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.
- on—Specifies the transmitter is enabled when port is in redundant mode
- off—Specifies the transmitter is disabled when port is in redundant mode
