Active Interface and Inactive Interface
Active interfaces refer to the interfaces that are in active state and are responsible for forwarding
data. The interfaces that do not forward data and are in inactive state are called inactive interfaces.
According to the operation modes, active and inactive interfaces are classified as follows:
l
l
Actor and Partner
In static LACP mode, the device in the link aggregation group with a higher LACP priority is
the Actor and the device with a lower LACP priority is the Partner.
Differentiating the Actor and the Partner is to keep the active interfaces of devices at both ends
consistent. If the devices at both ends select active interfaces according to the priority of their
own interfaces, the active interfaces may be different and the active links cannot be set up.
Therefore, the Actor is first determined. The Partner selects active interfaces according to the
priority of the interfaces of the Actor.

2.3 Configuring Link Aggregation in Manual Load
Balancing Mode
This section describes how to configure link aggregation in manual load balancing mode.

Manual load balancing mode: Generally, all member interfaces are active interfaces unless
a fault occurs on these interfaces.
Static LACP mode: The interfaces connected to M links are active interfaces that are
responsible for forwarding data; the interfaces connected to N links are inactive interfaces
that are used for redundancy backup.
