Note The default directory for installing the MWTM is /opt. In commands that call for the default directory,

if you installed the MWTM in a different directory, you must specify that directory instead of /opt.

Starting the MWTM Server

Before starting an MWTM server, verify that:

• Each node uses a supported IOS image

• The MWTM server has IP connectivity to each node

• SNMP is enabled on each node

• (Optional, but recommended) Traps are enabled on each node

• (Optional, but recommended) A trap host is defined on each node

Starting the MWTM Client

Tip For a definition of MWTM nodes, see What is ITP?, page 1-6 and What is RAN-O?, page 1-7.

Because the MWTM application comprises a server component and a client component, you must start both components to run the application.

To start the MWTM server on a Solaris or Linux system:

Step 1 You must be logged in as the root user or as a superuser, or your login must have administrator privileges.

To log in as the root user, see the Becoming the Root User (Server Only), page 4-2.

Note For details on setting up administrator privileges, see Specifying a Super User (Server Only),

Step 2 Enter:

# cd /opt/CSCOsgm/bin

# ./mwtm start

Chapter 4 Getting Started

page 2-18).

Becoming the Root User (Server Only)

Some MWTM procedures require that you log in as the root user.

Caution As the root user, you can adversely affect your operating environment if you are unaware of the effects

of the commands that you use. If you are a relatively inexperienced UNIX user, limit your activities as the root user to the tasks described in this manual.

If you are not logged in, log in as the root user:

> login: root > Password: root-password

If you are already logged in, but not as the root user, use the su command to change your login to root:

# su # Password: root-password

Chapter 4 Getting Started

Before Starting the MWTM Client

When you start an MWTM client, the version and release of the client must match that of the MWTM server.

If there is a client-server mismatch, the MWTM displays a warning message when you try to start the client. If you have a web browser installed, the MWTM optionally opens a web page from which you can download an allowed, matching client. See Downloading the MWTM Client from the Web, page

11-7 for more information about downloading the MWTM client.

Setting the DISPLAY Variable for Solaris or Linux Clients

If you see the following message upon client startup, you must set the DISPLAY variable:

Could not launch client: Can't connect to X11 window server using <x> as the value of the DISPLAY variable.

The DISPLAY variable is set as part of your login environment on Solaris or Linux. However, if you use Telnet or SSH to access a workstation, you must set the DISPLAY variable to local display by using this command:

# setenv DISPLAY local_ws:0.0

Starting the MWTM Client

where local_ws is your local workstation.

If your shell does not support the setenv command, enter:

# export DISPLAY=local_ws:0.0

Starting the MWTM Client on Solaris or Linux

To start the MWTM client on a Solaris or Linux system on which the MWTM server is installed, ensure that the MWTM server is running, then enter:

# cd /opt/CSCOsgm/bin # ./mwtm client

To start the MWTM client on a Solaris or Linux system other than the one on which the MWTM server is installed, ensure that the MWTM server is running, then enter:

# cd /opt/CSCOsgmClient/bin # ./mwtm client

To start the MWTM client on a Solaris or Linux system other than the one on which the MWTM server is installed, and connect to an MWTM server other than the default server, enter:

# cd /opt/CSCOsgmClient/bin # ./mwtm client

where server_name_or_ip_address is the name or IP address of the Solaris or Linux system on which the MWTM server is running.

Discovering Your Network

Access the Node

You use the MWTM to link to the node by using the connection protocol (Telnet or SSH) that you set in the Node SNMP and Credentials dialog box (see Credentials Fields, page 3-21).

To access the node, right-click a node in a window, then choose Node > Connect to from the right-click menu.

Note If your client workstation does not have network access to the IP address of the node (that is, if the node

is behind a firewall or NAT device), you might be unable to access the node.

Starting the MWTM Client on Windows

To start the MWTM client on a Windows system, choose Start > Programs > Cisco MWTM Client > Launch MWTM Client, or double-click the MWTM Client icon on the Windows desktop.

Chapter 4 Getting Started

Discovering Your Network

This section provides details on using the MWTM to discover your ITP or RAN-O networks. It includes:

• Discovery Overview, page 4-4

• Launching the Discovery Dialog, page 4-6

• Loading Seed Nodes and Seed Files, page 4-7

• Running Discovery, page 4-13

• Verifying Discovery, page 4-21

Discovery Overview

The MWTM uses a Discovery process to populate the MWTM database, discovering the objects in your network.

You can run Discovery if MWTM User-Based Access is disabled; or, if it is enabled, and you are a Network Administrator or System Administrator. (For more information about user authorization levels in the MWTM, see Configuring MWTM User Account Levels (Server Only), page 2-5.)

To discover your network:

Step 1 Start the MWTM client, as described in Starting the MWTM Client, page 4-2.

Step 2 If you want to change SNMP settings, do so before running Discovery. See Configuring SNMP Settings,

page 3-15 for more information.

Step 3 If you want to discover ONS nodes and did not choose the option to discover your network during

installation, you must add the ONS nodes and set the credentials before running discovery (see Adding

Nodes, page 3-22 for more information.)

4-4

Step 4 Choose Network > Network Discovery from the MWTM main menu. The MWTM displays the

Discovery dialog box. See Launching the Discovery Dialog, page 4-6 for more information.

nodes in a seed file. See Saving a Seed File, page 4-9 for more information.

Note (ITP only) You can run Discovery multiple times to attempt to discover additional nodes based on the IP

addresses defined in the Stream Control Transmission Protocol (SCTP) links. If you are using a separate management VLAN to manage your nodes, but private or unreachable IP addresses for your SCTP connectivity, uncheck the Entire Network check box in the Discovery dialog box. Otherwise, Discovery attempts to reach those nodes continuously. Instead, enter all nodes to be discovered directly into the seed list and do a nonrecursive Discovery.

Launching the Discovery Dialog

To launch the Discovery dialog box and begin the Discovery process, choose Network > Network Discovery from the MWTM main menu. The MWTM displays the Discovery dialog box.

Figure 4-1 Discovery Dialog with Seed Settings Displayed

Chapter 4 Getting Started

You use the Discovery dialog box to load and configure seed nodes, and use those seed nodes to discover the objects in your network.

If you start the MWTM client and the MWTM database is empty (including the very first time you start the MWTM client), the MWTM automatically opens the Discovery dialog box so you can run Discovery and populate the database.

The Discovery dialog box contains:

• Discovery Dialog Menu, page 4-6

Chapter 4 Getting Started

Creating and Changing Seed Files Using a Text Editor

A seed file is simply an unformatted list of seed node names. To create a seed file by using a text editor, simply create a file and list the seed node names, one on each line, with no other formatting:

new-york-a new-york-b chicago-c

When you save and name the seed file, remember:

• You can use any letters, numbers, or characters in the name that your operating system allows,

except blanks.

• The MWTM saves the seed file with a .see file extension.

• The MWTM saves the seed file in the MWTM server’s seed file directory, seeds:

–

If you installed the MWTM in the default directory, /opt, then the seed file directory is /opt/CSCOsgm/seeds/.

–

If you installed the MWTM in a different directory, then the seed file directory resides in that directory.

When the MWTM loads the seed file, it verifies the syntax of the file, deleting blank lines and extraneous leading and trailing spaces as needed. The MWTM also verifies that each seed node name resolves to a valid IP address. If a name does not resolve to a valid IP address, the MWTM logs the erroneous entry and ignores it.

Discovering Your Network

For example, given this seed file:

new-york-a<space> <space>new-york-b zzzzzzzzzzzz <blank line> <tab>chicago-c<tab>

The MWTM loads these entries:

new-york-a new-york-b chicago-c

Running Discovery

Click the Discovery tab in the Discovery dialog box to discover the objects in your network.

To display the Discovery tab, launch the Discovery dialog box, as described in Launching the Discovery
