This chapter discusses monitoring the Cisco IP/VC 3530 VTA and using the Diagnostic menus. The topics include the following:
You can monitor ongoing VTA activity to help troubleshoot problems that may arise. There are two ways you can connect to the VTA to monitor ongoing activity. You can Telnet into the VTA, or connect the VTA to a computer through the serial port and use a terminal emulator. In either case, once you start the session with a running VTA, the monitoring starts immediately. This section describes how to use both methods to start a monitoring session.
You can monitor ongoing VTA activity using Telnet. To start a VTA Telnet session, perform the following steps:
Step 2 In the Open field, type telnet VTA_IP_address. A login prompt appears.
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 VTA activity.
You can use a terminal emulator to monitor ongoing VTA activity, to view VTA parameter status (diagnostics), and to set some VTA parameter. The terminal emulator accesses the VTA through the VTA serial port on the front panel. You can connect the computer directly to the VTA or through a modem. The connection requires a null cable, which we provide 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.
To connect the VTA directly to the computer for a terminal emulator session, perform the following steps:
Step 2 Connect the 9-pin female connector to the serial port (COM 1) on a PC.
Step 3 Launch the terminal emulation 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.
.
You can use a modem to connect a remote VTA to the computer you want to use for terminal emulator sessions. The modem allows you to troubleshoot VTAs in remote locations. To use a modem to connect to the VTA, perform the following steps:
Step 2 Connect the connector marked Unit on the Terminal/Modem cable to the VTA 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 application installed on the computer you want to use to connect to the remote VTA.
Step 6 Dial the phone number assigned to the modem connected to the VTA.
Step 7 Set the terminal emulator configuration parameters as follows:
Step 8 Click OK. The monitoring session starts after you set the terminal emulator configuration parameters.
You can monitor the VTA using the diagnostics utility. The diagnostics utility allows you to view information about the following:
To access the terminal emulator diagnostic utility, perform the following steps:
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 VTA. The default name is admin.
Step 4 At the Password prompt, type the password that is required to log in to the VTA. 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.
This section describes options in the Remote Diagnostic Main Menu.
The Remote Diagnostic Main Menu lists the options you can use to view the current configuration of some VTA parameters. Figure 7-1 displays the Remote Diagnostic Main Menu.

A special configuration menu allows you to configure some VTA parameters in the terminal emulator. The menu is available only for a brief period after the VTA boots to start a terminal emulator session. You can use this configuration menu to configure IP address information, to change the password, and to set special configuration parameters that are not available in the GUI. This section describes how to access the terminal emulator configuration menu and provides information about each of the configuration options.
To access the configuration menu in the terminal emulator, perform the following steps:
Step 2 After the terminal emulator is launched, reboot the VTA. The boot menu appears on the screen.
Step 3 When the message "Press any key to start configuration" appears on the screen, press any key within 6 seconds. The Configuration Menu appears.
The terminal emulator configuration options are as follows:
This section describes how to use the Configuration Menu options. The Configuration Menu only appears after the gateway is turned on after being turned off. You can only exercise one option per Configuration Menu session.

Note Using the Configuration Menu to configure the gateway IP address is described in the "Setting the IP Address" in the "Installing the Hardware" chapter and is not describe here. |
The VTA has a specific set of bandwidth that it uses for videoconference calls. This section describes how to disable and re-enable bandwidths users placing videoconference calls to the VTA/room system can use.
To change the status of bandwidths incoming callers can use, perform the following steps:
Step 2 Type 2 at the prompt and press Enter. The Choose 0,1,2,3,7,R,U to Toggle the Matching Suffix prompt appears.
Step 3 Type a choice---0, 1, 2, 3, 7, R, and U--- at the prompt and press Enter. You can make multiple choices on the same line by using a comma to separate your choices.
The choices 0, 1, 2, 3, and 7 corresponds to the first digit in the VTA service suffix shown in Table 5-5 in the "VTA Bandwidth Services" section in the "Configuring the VTA" chapter. Your selection changes the status of the unrestricted and restricted bandwidths associated with the suffix. If the status is currently on (the current status is shown within the braces [] next to the bandwidth listing in the prompt), it will change to off and the VTA will not register the affected bandwidths when it registers with the gatekeeper.
The choices R and U allow you to change the status of all the restricted, R, and all of the unrestricted, U, bandwidths. For example, if you enter R, all restricted bandwidths that are currently enabled are disabled and all restricted bandwidths that are currently disabled are enabled. The VTA will not register disabled bandwidths with the gatekeeper when i t registers with the gatekeeper.
Step 4 Type C to accept the changes. The gateway will continue the start up process including logging on to the gatekeeper. The emulator session will display the bandwidths the VTA registers.
This section describes how to set a new password for the gateway. To set a password, perform the following steps:
Step 2 Type p at the prompt and press Enter. The Enter new password prompt appears.
Step 3 At the prompt, type the new password you want to assign to the gateway, and press Enter. A verify password prompt appears.
Step 4 Type the new password at the verify prompt and press Enter. The gateway resets using the parameter you have set.
This section describes how to set the gateway T.120 parameter. To set this parameter, perform the following steps:
Step 2 Type d at the prompt and press Enter. The T.120 communications support prompt appears.
Step 3 At the prompt, type 0 to disable T.120 support or type 1 to enable T.120 support, and press Enter. T.120 support is enabled by default. The gateway resets using the parameter you have set.
