Installation Overview and Planning
Revised: March 11, 2011, OL-18332-04
This chapter provides overview and planning information for installation of the Cisco Media Gateway
Controller (MGC) Node Manager (MNM). Chapter 2 provides detailed installation procedures.
Note
In Cisco MNM Release 2.8(1), the Cisco Voice Services Provisioning Tool (VSPT) is packaged with
Cisco MNM.
The following topics are covered in this chapter:
•
Installation Overview, page 1-1
•
Determine Your Hardware Requirements, page 1-2
•
Installation Checklist, page 1-5
Installation Overview
Successful network management using Cisco MNM begins with a well planned and carefully executed
installation. Network element management involves many interdependent factors, including:
•
The correct Sun server for your network size
•
The correct software release and patch levels on managed devices
•
The correct installation of Cisco Element Management Framework (EMF), the foundation software
for Cisco MNM
•
Performing installation tasks in the required order, so that required items are in place
To organize the installation process, use the Installation Checklist, page 1-5, to plan and execute your
installation. Read through the checklist and check off each task as it is completed.
Who Should Install Cisco MNM?
Installing Cisco MNM involves setting up hard drives, and checking and modifying system files, tasks
that are best performed by a system administrator with good knowledge of the Solaris operating system.

Determine Your Hardware Requirements
The hardware required and the way Cisco MNM is installed depend on the size of the network you are
managing and the amount of data you collect. Use this section to determine your hardware requirements
and software configurations.
Cisco Element Management Framework (Cisco EMF) and Cisco MNM consist of server and client
software. You can manager all small, medium, and most large networks from a single server, using the
Sun T5220 server which combines the client and server software. The multicore, multithread
architecture of the Sun T5220 servers works well with the Virtual Network Computing (VNC)
technology. It gives each VNC server a processor thread, and keeps the X-terminal traffic off the
network. The combination of the Sun T5220 server and VNC for Cisco MNM provides excellent
response time, even when your access is over WAN network connections.
Here is a breakdown of the client and server roles:
Server Software
•
Network management, including management of databases that contain network information, store
alarms, and performance data
•
GUI applications, with user interaction, when Cisco MNM is installed on a standalone server
Client Software
•
GUI applications, with which users interact.
The Cisco EMF and Cisco MNM software run on a separate machine, or on machines other than the
Cisco MGC host. In a small network, server and client software might reside on a single machine (a
standalone configuration). In larger networks, the software is installed on two or more machines in the
following distributed configuration:
•
One machine, known as the management server, contains the server software (including the
ObjectStore database management software in the Cisco EMF) and client software.
•
One machine, known as the presentation server, contains the client software only. In some large
networks, more than one Presentation server might be required.
In either configuration, users typically access Cisco MNM from X terminal workstations that run the
Client software through a Telnet session. In the distributed configuration, the X terminal workstations
connect directly to the Presentation server to run the client software.
See the standalone and distributed configurations illustrated in Figure 1-1.

Note
The management server is sometimes called the database server. The presentation server is sometimes
called the client, GUI, or application server. To avoid confusion, this document uses management server
and presentation server consistently, and these terms denote the machines in a distributed configuration,
not the software that resides on them.
The Cisco MNM client simultaneously supports up to ten X terminal users or VNC users. The exact
number supported in a given installation depends on your processing resources, and the network size.
Supported Configurations
The following configurations are supported:
•
Cisco MNM and Cisco VSPT installed together on a server (recommended)

Caution
•
Cisco VSPT (only) installed on a Cisco PGW 2200 Softswitch host machine
•
Cisco MNM installed on a server and Cisco VSPT installed on a separate server
Cisco MNM is not supported on a Cisco PGW 2200 Softswitch host machine.
Hardware Recommendations
Before you find the suitable hardware platform for Cisco MNM, determine your network deployment
size. Table 1-1 gives guidance on how to determine your network deployment size.

You have two options to get the hardware platforms for Cisco MNM:
•
Reuse old Sun SPARC-based platforms.
You cannot use Sun OPETRON-based platforms or X86 platforms for Cisco MNM. Old Sun
SPARC-based platforms, Sun Fire 240 and Sun Netra 240, were fully tested with Cisco MNM. Other
old Sun SPARC-based platforms might be interoperable.
•
Order new hardware platforms.

1. Two-drive machines work for smaller networks that have less traffic and fewer operators. Response time to operator commands increases as the network
grows and additional operators are added.
Note
The Cisco MNM host machine requires the minimum number of drives indicated in Table 1-2. These are
recommendations to aid you in planning. The total amount of disk space required depends on many
factors, such as the amount of alarm and performance data collected.

Disk Drives and Database Storage
In a medium or large network, using multiple disk drives to store databases helps alleviate I/O
bottlenecks and improves software performance. If you are using multiple disk drives for database
storage, or you expect to generate large database files, use raw partitions, as described in the Cisco
Element Management Framework Installation and Administration Guide at
http://www.cisco.com/en/US/docs/net_mgmt/element_manager_system/3.2_service_pack_7/installatio
n/guide/3_2p7adm.pdf
Note
If you are using UNIX File System (UFS) partitions, installing more than one drive for database storage
does not improve performance because the databases cannot span multiple partitions.
Installation Checklist
This checklist summarizes the tasks required for an initial installation of Cisco MNM. The procedures
for completing each task are provided in the following chapter.
We recommend that you print out the checklist and use it during the installation. Perform the tasks in
sequence unless otherwise noted.
Before You Begin
Read the release notes. If information there differs from what is presented here, use the information in
the release notes.
You can find installation tasks in Table 1-3.

Installation Tasks (continued)
Task
Description
Task 7: Install CiscoView 6.1.8 on a Solaris 10
Operating System.
This task is required only if you want to manage
Cisco IP Transfer Point - LinkExtenders
(Cisco ITP-Ls) or LAN switches from Cisco MNM,
which uses the CiscoView server as the
management interface.
CiscoView now ships as part of LAN Management
Solution (LMS) 3.1 with MGC Node Manager.
Only the CiscoView part of LMS is provided. To
obtain licenses for other LMS features, order LMS
3.1 from the Cisco.com website.
Cisco MNM Release 2.8(1) includes CiscoView for
Solaris 10 only. CiscoView for Solaris 8 is not
provided with the Cisco MNM media kit. However,
old CiscoView versions shipped with previous
Cisco MNM media kits can be re-used. New Cisco
MNM customers should be using Solaris 10 for the
best long-term satisfaction and full CiscoView
support. New Cisco MNM customers who only use
Solaris 8 operating systems must obtain CiscoView
for Solaris 8 separately, possibly by purchasing the
appropriate LMS 2.5.1 package.
Task 8: Install Cisco EMF 3.2.
—
Task 9: Install Cisco MNM Release 2.8(1) and
Verify the Installation.
If you want to install other element managers to run
co-resident with Cisco MNM, install them now.
Task 10: Set Up the X Terminal Workstations for —
Remote Access.
Task 11: Synchronize Time.
—
Task 12: Configure Network Devices to Forward This task, which must be completed before Cisco
Alarms.
MNM can collect alarm information from network
devices, is covered in Chapter 2 in the “Configuring
Network Devices for Management” section of the
Cisco Media Gateway Controller Node Manager
User Guide, Release 2.8(1).
