Member interface states
A member interface of a Reth interface can be in either of the following states:
Active—The interface can forward packets. A Reth interface can have only one active member interface.
Inactive—The interface cannot forward packets.
A Reth interface determines the state of its member interfaces by using the following rules:
When the member interfaces are physically up, the member interface with the higher priority is active. The other member interface is inactive. The priority of an interface can be configured at the CLI.
When the member interfaces are physically down, both interfaces are inactive.
When the active member interface goes down physically, the inactive interface automatically becomes active to forward packets.
If the Reth interface is added to a redundancy group, the member interface state is determined by the redundancy group. For more information, see "Configuring redundancy groups."
