Configuring Container Interfaces
The JUNOS Software supports container interfaces for APS on SONET links. Physical
interfaces and logical interfaces remain up on switchover, and their APS parameters
are auto-copied from the container interface to the member links. See "Container
Interfaces Overview" on page 38 for more information.
Container interfaces support the following features:
Cisco HDLC or PPP encapsulation methods.
Unpaired groups.
Bidirectional APS.
Non-container and container-based APS on the same system.
Use of any combination of (nonchannelized) SONET interfaces installed on the
same router.
To configure a container interface, you must first create the number of container
devices that you require. You can create up to a maximum of 128 container interfaces
per router using the
device-count
hierarchy level. You can create more container interfaces later if required, up to 128
(total). The resulting container interfaces are designated sequentially from
a maximum of , depending on the

interfaces can be assigned to any container interface
To configure each container interface, you must assign two SONET interfaces
( so-fpc/pic/port ) using the
member-interface-speed speed
Within each of the two SONET interfaces' container options, you must set one
container-type as primary
(corresponding to an APS protect circuit). For each SONET interface, you

can also use the allow-configuration-override
configuration of a member link to override the container configuration.
The following configuration steps are required:
Specify the total number of container interfaces (up to 128) to create using the
