Chassis Commissioning and Subchassis Discovery

After you deploy a chassis, the next step in creating a manageable system is to commission the chassis
(which begins the process of subchassis discovery). The following figure shows a Cisco3662–AC
chassis map before subchassis discovery. Subchassis discovery identifies all physical objects (that is,
modules and interfaces) within the chassis and places them into the chassis map.
Figure 3-20 Before Subchassis Discovery
Line cards and interfaces located within the chassis are discovered at this time. Commissioning not only
discovers the chassis and all the physical objects within the chassis, but also initiates heartbeat polling,
which allows alarms to be raised on the chassis and all physical objects within the chassis.
Because the chassis is the highest–level object, all objects under the chassis are commissioned as well
when you commission the chassis. One level down, if you commission a module interface, you
commission all physical objects underneath that level. If you commission a port adapter, you
