Chapter 1 Preparing for Configuration
Cisco MGX Switch Features
Narrow Band Service Modules (NBSMs) in Cisco documentation.) The CBSM term is used to refer
to this class of cards as a whole. CBSM cards include the AUSM, CESM, FRSM, 8-port MPSM,
RPM, RPM-PR, and VISM card families.
Note
The AXSM and FRSM-12-T3E3 cards are not CBSMs. They are full-height cards that
communicate with the PXM45 and other service modules through the serial bus.
Once you have installed your switch and completed the general configuration procedures described in
this guide, refer to the service module documentation for information on provisioning and managing
individual services such as ATM, circuit emulation, Frame Relay, and IP.
This chapter introduces the Cisco MGX multiservice switches and common switch topologies, provides
an overview of the configuration process, and presents guidelines for collecting the information you will
need to complete the configuration.
