Cisco MGX 8800/8900 Series Software Configuration Guide
Release 5.1, Part Number OL-6482-01, Rev. A0, January 25, 2005
Chapter 1 Preparing for Configuration
Changes to this Document
• Cisco MGX Release 5.1 software supports a number of single-height service modules (listed in
Table 1-3) that were originally designed to operate in Cisco MGX 8850 (PXM1) switches. These
service modules use the cell bus to transport traffic to other services modules or PXM uplinks and
are commonly referred to as cell bus service modules (CBSMs). (The CBSMs have also been called
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, MPSM, RPM, RPM-PR, and VISM card families.
Note The AXSM , FRSM-12-T3E3 , RPM-XF, and VXSM cards are not CBSMs. They are full-height
cards that communicate with the PXM45 and other service modules through the serial bus.
• The MGX switch does not support synchronization with daylight savings time even if the node is
connected to the SNTP server and is receiving UTC.
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.
