Monitoring the Gateway

Monitoring the Gateway

This chapter describes monitoring the gateway using the Diagnostic utility. The topics include:

Monitoring Cisco IP/VC 3520 Gateway Activity

You can monitor ongoing gateway activity to help troubleshoot problems that may arise. There are two ways you can connect to the gateway to monitor ongoing activity. You can Telnet into the gateway or connect the gateway to a computer through the serial port and use a terminal emulator. In either case, once you start the session with a running gateway, the monitoring starts immediately. This section describes how to use both methods to start a monitoring session.

Starting Telnet Session

You can monitor ongoing gateway activity using Telnet. To start a gateway Telnet session, perform the following steps:


Step 1 On the Windows desktop, choose Start > Run. The Run dialog box appears.

Step 2 In the Open field, type telnet gateway_IP_address.

Step 3 At the prompt, type the login name required for the VTA. The default name is admin.

Step 4 Click OK. The Telnet session starts.

The Telnet session displays the ongoing gateway activity.


Starting a Terminal Emulator

You can use a terminal emulator to monitor ongoing gateway activity, to view gateway parameter status (diagnostic), and to set some gateway parameter. The terminal emulator accesses the gateway through the gateway serial port on the front panel. You can connect the computer directly to the gateway or through a modem. The connection requires a null cable, which Cisco provides in the Terminal/Modem cable shipped with the unit. This section describes how to set up a terminal emulator session through direct connection and through a modem.

Connecting the Gateway Directly to the Computer

To connect the gateway directly to the Computer for a terminal emulator session, perform the following steps:


Step 1 Connect the 9-pin male connector of the Terminal/Modem cable to the serial port on the gateway front panel.

Step 2 Connect the 9-pin female connector to the serial port (COM 1) on a PC.

Step 3 Launch the terminal emulation software on the PC.

Step 4 Set the terminal emulator configuration parameters to the following values:

Step 5 Click OK. The monitoring session starts after you set the terminal emulator configuration parameters.


.

The monitoring session starts after you set the terminal emulator configuration parameters.

Using a Modem to Connect the Gateway to the Computer

You can use a modem to connect a remote gateway to the computer you want to use for terminal emulator sessions. This allows you to troubleshoot gateways in remote locations. To use a modem to connect to the gateway, perform the following steps:


Step 1 Make sure that the modem can communicate with the computer you are using.

Step 2 Connect the connector marked Unit on the Terminal/Modem cable to the gateway serial port.

Step 3 Connect the connector labeled Modem on the Terminal/Modem cable to the modem.


Note If a Terminal/Modem cable is not available at the remote site, you must use a null modem cable with the appropriate connectors. See the appendix "Cable Connectors and Pinouts" to view the wiring configuration for a null modem cable.

Step 4 Configure the modem parameters as follows:

Step 5 Launch the terminal emulator installed on the computer you want to use to connect to the remote gateway.

Step 6 Dial the phone number assigned to the modem connected to the gateway.

Step 7 Set the terminal emulator configuration parameters as follows:


The monitoring session starts after you set the terminal emulator configuration parameters.

Using the Terminal Emulator to View Gateway Parameters

You can monitor the gateway using the diagnostics utility. The diagnostics utility allows you to view information about the following:

Accessing the Diagnostic Menus

To access the terminal emulator diagnostic utility, perform the following steps:


Step 1 Connect the gateway to a computer through the serial port and start a terminal emulator session. (See the "Starting a Terminal Emulator" section earlier in this chapter.)

Step 2 When the prompt appears, type diag.

Step 3 At the User Name prompt, type the name that is required to log in to the gateway. The default name is admin.

Step 4 At the Password prompt, type the password that is required to log in to the gateway. The default password is cisco.


Note The Remote Diagnostics program allows you five chances to enter the correct User Name and Password before exiting the program.

The Remote Diagnostic Main Menu appears.
