Overview IP Telephony Manager, previously known as Total Control Manager is a

software application that runs on a UNIX management station. This application remotely manages CommWorks Network Application Cards (NACs) and Network Interface Cards (NICs) through a Network Management Card (NMC) installed on the CommWorks 5210 IP Telephony Platform.

Two protocols govern these management functions: Simple Network Management Protocol (SNMP) between the NMC and the management station, and a proprietary CommWorks protocol between the NMC and the managed cards.

IP Telephony Manager communicates with the NMC through SNMP rules. Because the other NACs in the hub do not use SNMP agent software, the NMC acts as a proxy agent between these cards and the management station.

Standard SNMP traps can be enabled to send a trap message (or event notification) to one or more management stations. The management stations use these traps to create logs, trigger alarms, and initiate actions.

18 CHAPTER 1: INSTALLATION

The management station uses Management Information Bases (MIBs), defined for each card in the hub, to issue commands to the NMC. The NMC executes the commands and obtains the results using a proprietary CommWorks protocol. The NMC uses SNMP to send these results to the management station.

The NMC communicates with each installed card using a proprietary Management Bus Protocol (MBP). The NMC provides configuration management for each NAC in the hub and can set each parameter for a NAC to a specific value. The NMC also configures parameters to predetermined values when a NAC is installed in the hub. To help manage the configuration, the NMC can query the current value of parameters for each NAC and download software for upgrades.

Management Workstation

You can use HP OpenView or the CommWorks 5000 Network and Service Management System to monitor the status of all elements of the CommWorks platform and to act as an alarm server.

Use IP Telephony Manager to configure and monitor all the components of the

CommWork’s platform, such as configuring operational parameters, upgrading software, and backing up and restoring configurations.

If you are installing HP OpenView for the first time, temporarily disable autodiscovery. Do not allow OpenView to discover the devices on your network automatically. This eases integration with IP Telephony Manager. You can enable autodiscovery after you install IP Telephony Manager.

Before You Begin Before installing IP Telephony Manager on your system:

■ Read the readme file (located at /cdrom/cdrom0/tcm/tcm_sol). It contains IP

Telephony Manager installation notes.

■ If you are integrating IP Telephony Manager with HP OpenView Network

Node Manager, install and start HP OpenView.

■ Remove any previous versions of IP Telephony Manager.

This chapter assumes you are running the Korn shell. For installation instructions for the C or Bourne shells, refer to the readme file.

20 CHAPTER 1: INSTALLATION

If you are using HP OpenView, you must install it before you install IP Telephony Manager. If not, HP OpenView does not integrate correctly. Make sure IP Telephony Manager and HP OpenView are installed on the same system. Remember to disable HP OpenView autodiscovery before you do a first time install/integration of IP Telephony Manager with HP OpenView.

Removing Previous Versions

Option 1 To remove a previous version of IP Telephony Manager without erasing your

Option 2 To completely remove a previous version of IP Telephony Manager, including all

When you remove IP Telephony Manager, you can either save your existing configuration, data, and log files (retaining chassis IP addresses and configuration information) or erase these files when you remove IP Telephony Manager.

CommWorks recommends that you save the existing configuration, data, and log files - (Option 1).

existing IP Telephony Manager database files:

1 Typ e cd $TCMHOME. 2 Typ e ./Remove.

IP Telephony Manager database files:

1 Typ e cd $TCMHOME. 2 Typ e ./Remove -c.

Installing IP Telephony Manager

To install IP Telephony Manager:

1 Move to the drive and directory that contains the installation files. 2 Create a directory for the software installation. 3 Set the TCMHOME variable to point to that directory. 4 Log in to the UNIX workstation as root. 5 Insert the CommWorks CD. 6 Mount the cdrom drive if necessary. 7 Typ e: cd <working directory> (for example, cd /cdrom/cdrom0/tcm/tcm_sol).

Installing IP Telephony Manager 21

8 From the command line prompt, type the following commands and press

Return after each:

TCMHOME=<installation directory> (for example, /opt/tcm)

export TCMHOME

mkdir -p $TCMHOME

cd cdrom/cdrom0/tcm_sol (for HP, tcm_ux)

./install

A message appears:

The script will make adjustments, only as needed, to system files in /etc/imit.d, the crontab, /etc/services, and /usr/lib/x11.

If TCM is later removed, these adjustments will be undone to restore the original state.

Setting PATH and

LD_LIBRARY_PATH

Do you wish to continue [y/n]

9 Typ e y, and then press Return.

The installation proceeds, listing files as they are installed. The following message appears to indicate the installation has completed successfully:

TCM installation is complete

You can now enable HP Overview autodiscovery on your system.

Before you can start IP Telephony Manager, you must add $TCMHOME to the PATH statement and indicate the location of the IP Telephony Manager library files as follows:

From the command line prompt, type the following commands and press Return after each:

PATH=$PATH:$TCMHOME/bin

export PATH

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$TCMHOME/lib

export LD_LIBRARY_PATH

22 CHAPTER 1: INSTALLATION

Starting IP Telephony Manager

After you complete the installation and modify the path statement, you can start IP Telephony Manager.

To start the IP Telephony Manager, from the command line prompt, type one of these commands:

# xtcmvfpd

# xtcmvfpd <target chassis IP address>

The first command causes a list of the chassis components to display. You can then select the component that you want to start. The second command specifies the IP address of the component that you want started.

The IP Telephony Manager graphical user interface (GUI) opens a virtual display of the target chassis. If the virtual display does not appear, set and export the paths according to the instructions in this chapter.

For a complete description of the menus on the GUI, refer to Chapter 3

Navigating and Using the System

Connecting to Entities

CommWorks IP Telephony Manager lets you configure and monitor any CommWorks IP Telephony entity (for example the Media Gateway, Gatekeeper, Accounting Server, Billing Support Server.) on your system. To connect to the individual entities:

1 Start IP Telephony Manager. 2 Click File, and click Open, and then click New from the IP Telephony Manger

Console window.

3 Enter the name and IP address of the entity. 4 Verify that the community strings are as follows:

■ Read-only is public (case sensitive)

■ Read/write is private (case sensitive)

To modify these default settings, refer to Chapter 4, topic: Changing the SNMP

Community Strings.

5 Click OK.

Connecting to Entities 23

To view the entity after the it is connected using IP Telephony Manager:

1 Start IP Telephony Manager. 2 Click File and then click Open from the IP Telephony Manger Console

window.

3 Select the entity from the list. 4 Click OK.

The entity appears in graphical form. When selected, the entity is blue; when deselected, the entity is black.

Determining

Gatekeeper and Media

Gateway Connectivity

To test Gatekeeper to Media Gateway connectivity, use the following procedure.

1 Using IP Telephony Manager Console window, select the edge server card. 2 On the menu bar, select Performance and then Performance Monitor.

The Select Entity window appears.

3 Select the entity 3Com Gateway and then click OK.

The Performance window appears.

Figure 1 Performance Window

4 Select Gatekeepers from the Functional Group. 5 Select Current Gatekeeper IP address and click Add. Click OK.

A real time table appears and displays the selected Gateway and the Gatekeeper to which it is registered. The IP address of the Gatekeeper to which it is registered also appears.

24 CHAPTER 1: INSTALLATION

Integrating with HP OpenView

The IP Telephony Manager installation script installs OpenView integration files to the appropriate OpenView Network Node Manager subdirectories.

OpenView integration occurs as part of the IP Telephony Manager installation, when the OpenView environmental variables are set beforehand. To integrate IP Telephony Manager with OpenView manually, follow the procedure below.

1 Set the OpenView environmental variables.

# cd /opt/OV/bin

# . ./ov.envvars.sh

2 Test the environmental variables.

# cd $OV_BIN

# pwd

Solaris responds as follows:

/opt/OV/bin

3 Change to the directory that contains the integration files.

# cd $TCMHOME/ovw

4 Install the integration files.

# ./Install

You can run the $TCMHOME/ovw/Install script at any time. You do not need to run $TCMHOME/ovw/Remove before running $TCMHOME/ovw/Install again.

HP OpenView integrates the IP Telephony Manager icons; this lets you access IP Telephony Manager from HP OpenView.

Fixing Incorrect Maps If you populate CommWorks devices in OpenView before you installed IP

Telephony Manager, IP Telephony Manager integration does not change the component type from a non-CommWorks type to a CommWorks chassis type. You cannot do this automatically in HP OpenView. For best results, delete and rediscover the CommWorks devices.

You can also use the OpenView ovtopofix -r -o <object id> command. CommWorks object IDs 1.3.6.1.4.1.429.2.1 through 1.3.6.1.4.1.429.2.9 must each be individually specified.

Integrating with HP OpenView 25

If CommWorks devices were populated in OpenView before IP Telephony Manager was installed, the network map will not display the CommWorks bitmaps correctly after IP Telephony Manager integration. This occurs even if the CommWorks menu options are not enabled and the isUSREntNetHub capability is not set to True. For best results, delete and rediscover the CommWorks devices.

Removing HP

OpenView Integration

Erasing IP Telephony

Manager

Verifying the

Installation

To remove OpenView integration:

1 Login as root. 2 Type the following:

cd $TCMHOME/ovw

./Remove -r

While all CommWorks files are removed from HP OpenView, no changes are made to the runtime databases. One of the primary purposes of removal is to prepare for a new installation.

To erase IP Telephony Manager from HP OpenView, replace the current maps with new ones. You can also delete and rediscover all the CommWorks devices from each map.

Start IP Telephony Manager with the following commands:

> TCMHOME=<installation directory>

> export TCMHOME

> PATH=$PATH:$TCMHOME/bin

> export PATH

> ./xtcmvfpd <TCH IP_Address/HostName>

IP Telephony Manager opens.

Component Configuration

The IP Telephony Manager Console window is used to select target components whenever you are performing configuration, sending commands, or upgrading components through software download.

Launching the

Configuration Tool

There are two ways to launch the Configuration Tool:

■ From the IP Telephony Manager Console, select a target from the IP

Telephony Manager Console window, and then from the Configuration menu, select Programmed Settings.

■ From the UNIX command line, type xtcmconf followed by the IP address or

hostname of the target device and the target slots and channels (refer to

Synchronizing Network Time

Appendix B Command Line Interface

You must synchronize the system time of each component in the network accurate tracking of the IP telephony traffic. To achieve system

for more details).

synchronization, set each Gatekeeper, SIP Proxy Server, and Back-end Server to Greenwich Mean Time (GMT) and use the Network Time Protocol (NTP) on all system components.

Setting the Time Zone For each Gatekeeper, SIP Proxy Server, and Back-end Server in the IP telephony

network, set the time zone to GMT.

Recording the NTP IP

Addresses

1 From the Windows desktop, click Start, then Settings, and then click Control

Panel.

2 Double-click Date/Time.

The Date/Time Properties window appears.

3 Click Time Zone. 4 From the drop-down list, select [GMT] Greenwich Mean Time: Dublin,

Edinburgh, Lisbon, London.

5 Click OK.

NTP uses a primary and a secondary NTP time server for system time. You can use the IP addresses of NTP time servers that are local to your network, or you can use public NTP time servers. The IP addresses of public NTP time servers are available on the internet. Use the following procedure to record a primary and secondary NTP time server address.

Selecting Local NTP Servers

If your local network includes local NTP time servers, record the IP address of the primary NTP time server and the secondary NTP time server.

Synchronizing Network Time 29

Selecting Public NTP Servers

1 From any computer with internet access, access the following website:

http://www.eecis.udel.edu/~mills/ntp/clock1.htm

2 From the website, record the IP addresses for two separate active servers. One

is used as the primary NTP server, and the other is used as the secondary NTP server. We recommend choosing NTP server locations that are as close to the Media Gateway chassis as possible.

Setting the NTP

Parameters

Use NTP to synchronize the time across the network. The NTP parameters must be set for the HiPer NMC card in each Media Gateway chassis, the Gatekeepers, SIP Proxy Servers, and the Back-end Servers.

All Media Gateway chassis components are automatically synchronized through the controlling HiPer NMC after it is configured for NTP.

Setting the NTP Parameters for the HiPer NMC

For the HiPer NMC card in each Media Gateway chassis, do the following:

1 Using IP Telephony Manager, open the Media Gateway chassis. 2 Select the HiPer NMC card. 3 Click Configuration, then Programmed Settings from the IP Telephony

Manager Console window.

4 Select Network Time Protocol from the Parameter Group drop-down list.

The Network Time Protocol windows appears.
