RPM Port Numbering

This section describes how RPM ports are numbered so that when you configure the RPM you can correctly identify the interfaces.

Definition

The port-numbering scheme on the RPM is as follows:

  • LAN interfaces are identified as chassis-slot/slot/port.

  • The top-rear interface card is slot 1.

  • The bottom-rear interface card is slot 2.

  • Ports are numbered 1 to 4 from top to bottom.

  • The ATM cell bus interface is always port 1.
