Release Information

Statement introduced in Junos OS Release 14.2R3.

Description

Specifies the time period for which the Link Aggregation Control Protocol (LACP) maintains the state of a child (member) link as expired or default.

When a child link goes from the current state to the expired state, the LACP monitors the reception of protocol data units (PDUs) on the child link for the configured hold-up time interval and does not allow the child link to transition back to the current state. This configuration thus prevents excessive flapping of a child link on an aggregated Ethernet interface.

The configured hold-up timer value is applicable to all the child links within a link aggregated (LAG) interface. By default, this feature is disabled.

Options

timer-value—Hold-up interval in seconds.

Required Privilege Level

interface—To view this statement in the configuration.

interface-control—To add this statement to the configuration.
