Configuring Controllers
There are three types of controllers for the line card. The controllers are the optics controller, the ethernet
controller, and the coherent DSP controller. This chapter describes the procedures used to configure these
controllers.
Note
Unless otherwise specified, "line cards" refers to 1.2T and 1.2TL line cards.

AINS
The Automatic-In-Service (AINS) feature allows the controller to automatically move to the
automatic-in-service state after the maintenance window is completed. A soak time period is associated with
the AINS state. The controller automatically moves to the In-Service state after the soak time period is
completed. During the AINS maintenance window, alarms are not propagated to the EMS/NMS monitoring
system.
You can configure AINS on the client ports of the card.

Layer 2 is also known as the data link layer that runs on all Cisco devices, such as routers, bridges, access servers, and switches. This protocol allows the network management applications to automatically discover and learn about other Cisco devices that connect to the network.
