Cisco MGX 8850 (PXM45) and MGX 8950 Software Configuration Guide
Release 3, Part Number 78-14788-01 Rev. C0, January 2004
Chapter 1 Preparing for Configuration
Collecting Information
Chapter 6, “Provisioning AXSM Communication Links,” describes how to configure ATM
communications on ATM Switching Service Module (AXSM) lines and how to configure different types
of connections to other ATM devices.
For instructions on configuring different ways to manage the Cisco MGX 8850 and the Cisco MGX 8950
switches, see Appendix C, “Supporting and Using Additional CLI Access Options.”
Collecting Information
To successfully configure the Cisco MGX 8850 and the Cisco MGX 8950 switches, you must collect
information about the other devices to which it will connect. Also, you need to know the line speeds and
protocols used on the trunks that connect to the switch. For PNNI routing, you also need to have an
addressing plan for the network in which the switch is installed. This information can be grouped into
the following categories:
• General configuration data
• Edge device and ATM device trunk data
• Core node trunk data
The following sections introduce these types of data and provide guidelines for collecting the data.
General Configuration Data
During configuration, you will need to enter general configuration data that describes the switch and how
it will be used in the network. This data includes
• Unique switch name
• ATM addressing plan
• IP addressing plan
• Administrator data
• Network clock source plan
• Network management plan
• Line and trunk data
The following sections describe these topics in more detail.
Unique Switch Name
Each switch must have its own name (which consists of up to 32 characters), unique within the ATM
network. If you are adding a switch to a network, find out if the network administrator has established
switch naming conventions, and find out which names have already been used. It is a good practice to
name switches according to location, as such names convey both the switch identity and its location. The
procedure for setting the name is described in “Setting and Viewing the Switch Name” in Chapter 2,
“Configuring General Switch Features.”
