Configuring LACP on Chassis Clusters
LACP is configured on redundant Ethernet interfaces at the [edit interfaces interface-name redundant-ether-options] hierarchy.
Configuring LACP
You configure LACP on a redundant Ethernet interface by setting the LACP mode for the parent link with the lacp statement. The LACP mode can be off (the default), active, or passive.
LACP is enabled by setting the mode to either passive or active. If the actor and partner are both in passive mode, they do not exchange link aggregation control PDUs, which results in the redundant Ethernet links not coming up. If either the actor or partner is active, they exchange link aggregation control PDUs. To initiate transmission of link aggregation control PDUs and response link aggregation control PDUs, you must enable LACP at both the local and remote ends of the links, and one end must be active.

Configuring the Link Aggregation Control PDU Transmit Interval
You configure the interval at which the interfaces on the remote side of the link transmit link aggregation control PDUs by configuring the periodic statement on the interfaces on the local side. It is the configuration on the local side that specifies the behavior of the remote side. That is, the remote side transmits link aggregation control PDUs at the specified interval. The interval can be fast (every second) or slow (every 30 seconds).
By default, the actor and partner transmit link aggregation control PDUs every second. You can configure different periodic rates on active and passive interfaces. When you configure the active and passive interfaces at different rates, the transmitter honors the receiver’s rate.
To configure the interval to be every 30 seconds:
