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
• If a failed clock source recovers, the switch will use not use the recovered clock source unless you
re-add it with the network with the cnfncdpclksrc command.
• Clock sources must be configured after the AXSM cards and lines are configured. For more
information, see “Configuring AXSM Line Clock Sources” in Chapter 6, “Provisioning AXSM
Communication Links.”
Note Cisco advises against running NCDP on VP trunks.
To develop an NCDP network clock source plan, create a topology drawing and identify all the
configured clock sources on each switch in the network. Identify the priority of each clock source.
Network Management Plan
You can use the following tools to manage the Cisco Cisco MGX 8850 and the Cisco MGX 8950
switches:
• Command line interface (CLI) provided with the switch
• Cisco WAN Manager
• CiscoView
• Third-party SNMP manager
The CLI that comes with the switch is the least expensive option. To use the other tools, you must
purchase Cisco WAN Manager (CWM) or a Simple Network Management Protocol (SNMP) manager.
The Cisco MGX 8850 and the Cisco MGX 8950 switches come with an SNMP agent for use with an
SNMP manager.
The advantage to using CWM or an SNMP manager is that you can use one program to simultaneously
manage multiple devices. Also, CWM is the only management tool that can configure Service Class
Templates (SCTs), which are described in Chapter 6, “Provisioning AXSM Communication Links.”
Most installations require at least one CWM workstation to complete the switch configuration.
Cisco View is a CWM component that can be used independently of CWM to provide limited monitoring
and management capabilities.
To determine which versions of CWM and Cisco View are compatible with this release, refer to the
Release Notes for Cisco MGX 8850 and MGX 8830 Software Version 3 (PXM45/B and PXM1E) or the
Release Notes for Cisco MGX 8950 Software Release 2.1.60.
For information on managing the switch with an SNMP manager, refer to the following: Cisco MGX
8850 and MGX 8950 SNMP Reference, Release 2.1.
Line and Trunk Data
When configuring lines and trunks that connect the switch to other devices, you need to collect the
following:
• Physical line type and configuration data
• ATM port configuration data
