# lacp

#### Syntax

lacp { active | passive }

no lacp

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Configures whether an Ethernet link in an IEEE 802.3ad link aggregation group (LAG) bundle participates actively or passively in the Link Aggregation Control Protocol (LACP). LACP controls the transmission of protocol data units (PDUs) to exchange information between partner links in a LAG bundle. By default, Ethernet links do not send LACP PDUs. The no version restores the default behavior.

#### Options

- active—Causes the Ethernet link to always transmit LACP PDUs, regardless of whether its partner link is set to active or passive LACP participation
- passive—Causes the Ethernet link to transmit LACP PDUs only when it receives LACP PDUs from its partner link

#### Mode
