Starting the Media Gateway

Starting the Media Gateway

This chapter describes how to set up a management console and configure MGX 8260 media gateway parameters.

Setting Up a Management Console

Setting up the MGX 8260 IP addresses requires a VT100-compatible terminal or PC connected to the console port. A laptop PC running terminal emulation software works efficiently for this task.

This section describes how to set up the MGX 8260 using Microsoft Windows HyperTerminal. The procedure for starting HyperTerminal varies by PC, so your startup procedure may differ somewhat from the one described in this chapter. You only perform the HyperTerminal setup procedure once for a specific PC. For later sessions, simply double-click the HyperTerminal icon for the configuration you defined.

The Cisco MGX 8260 console port has a standard EIA/TIA-232, DCE serial port. Its default settings are:

To start terminal emulation on Windows 95 or NT, follow these steps:


Step 1   From the Start menu, select Start > Programs > Applications > Hyperterminal

The Connection Description dialog box opens.

Step 2   In the Name field, enter a short name and then click OK. The Connect To dialog box opens.

Step 3   In the Connect Using field, select the desired COM port and then click OK.

The COM Properties dialog box opens.

Step 4   In the COM Properties dialog box, set bits per second to 9600, data bits to 8, parity to none,
stop bits to 1, flow control to none. Then click OK.

Step 5   In the Hyperterminal window, select File > Properties.

The Properties dialog box opens.

Step 6   Click the Settings tab and then select VT100 from the Emulation drop-down list. Then click OK.

Step 7   Click File; then click Save to save your terminal emulation settings for future use. You only have to perform this procedure once on a specific PC.

Step 8   If you have not already done so, connect an EIA/TIA-232 cable between the MGX 8260 console port of the active SCC and the PC. (Refer to "Cable and Connector Reference.")


You are now ready to log onto the Cisco MGX 8260 media gateway and initialize the equipment.

Initializing the Equipment

This procedure explains how to prepare a new system for basic operation by initializing the IP addresses and node parameters. You initialize the equipment using the command line interface during a console session.

Logging In

Before you can configure the Cisco MGX 8260 media gateway, you must log in as a user with the privilege to change system parameters. Use the default account to initialize the node.


Note   Before putting the MGX 8260 in service, replace this default account with a unique one.

To log in, follow these steps:


Step 1   With Hyper Terminal running and a connection made to the active SCC console, enter two carriage returns to obtain a login prompt.

Step 2   At the User Id prompt, enter SuperUser.

Step 3   At the Password prompt, enter cisco.

The Cisco MGX 8260 media gateway displays a command line prompt.


Configuring Management IP addresses

To communicate with the Cisco MGX 8260 media gateway over a network, set up IP addresses for the following types of network management:

The system management interface supports two IP addresses, one for each 10BASE-T Ethernet management port. If your system uses redundant subnetworks for system management, set both IP addresses. Otherwise, just set one system IP address.

The in-band IP address creates a virtual port for management over one of the Fast Ethernet (100BASE-TX) VoIP ports. The MGX 8260 must be equipped with an SCC-FE back card to use this option.

Before performing the following procedure, obtain IP addresses, subnet masks, and gateway addresses for the Cisco MGX 8260 media gateway from your system administrator.


Note   For additional information, refer to the Cisco MGX 8260 Command Line Interface Guide.

To configure IP addresses, follow these steps:


Step 1   Set the IP address and mask for the primary management interface using the chsysip1 command.

For example, with a system IP address of 10.15.26.20 and a 24-bit subnet mask, enter the following command and press Return:

chsysip1 10.15.26.20 255.255.255.0

Step 2   Set the IP address and mask for the secondary management interface using the chsysip2 command.

For example, with a system IP address of 10.15.27.20 and a 24-bit subnet mask, enter the following command and press Return:

chsysip2 10.15.27.20 255.255.255.0

Step 3   Specify the IP address of a gateway router for management traffic using the chgw command.

For example:

chgw 10.15.27.1

Step 4   Set the IP address and mask for the in-band management interface (via a SCC Fast Ethernet port) using the chibip command.

For example, with a system IP address of 10.15.28.20 and a 24-bit subnet mask, enter the following command and press Return:

chibip 10.15.28.20 255.255.255.0

Step 5   Check the IP configuration settings using the lsmgips command. The following example shows a sample output:

========================================================================= Management Interfaces Configuration (lsmgips) ========================================================================= SNMP Interface IP1 Address : 10.15.26.20 SNMP Interface IP1 Mask : 255.255.255.0 SNMP Interface IP2 Address : 10.15.27.20 SNMP Interface IP2 Mask : 255.255.255.0 SNMP Interface MAC Address : 00:50:a3:00:26:c8 In-Band Interface Address : 10.15.28.20 In-Band Interface Mask : 255.255.255.0

You can now manage the Cisco MGX 8260 media gateway using a Telnet session or Cisco WebViewer. For in-band management, you must configure additional parameters and connections. For more information, see the "Configuring the Management Interfaces" section of the
Cisco MGX 8260 Command Line Interface Guide.


Configuring System Settings

To configure the system location, date, and time, follow these steps:


Step 1   Specify system location information using the chndinf command.

For example, for an MGX 8260 located in shelf 10, at "CustomerSite", node 5, you would enter the following command:

chndinf 10 CustomerSite 5

Step 2   Set the system date with the chdate command, using the mm/dd/yyyy format.

The following example sets the system date to January 14, 2001:

chdate 01/14/2001

Step 3   Set the system time using the chtime command. Specify the time in hour:minute:second format followed by the time zone (optional). Express the time zone as the number of hours before or after GMT (Greenwich Mean Time), as shown in Table 6-1.

The following example sets the system time to 1 PM, Eastern Standard Time.

chtime 13:00:00 18

Where to Go from Here

The installation and startup procedures previously described prepare the Cisco MGX 8260 for system-wide configuration. After installing all system components, you can complete the configuration process and put the MGX 8260 in service.

Final configuration includes one or more of the following tasks:

To manage the Cisco MGX 8260 media gateway remotely, you need to configure the appropriate management interfaces and may need to configure in-band connections. For more information, see the "Configuring the Management Interfaces" section of the Cisco MGX 8260 Command Line Interface Guide.

Securing the Cisco MGX 8260 media gateway from unauthorized access is critical to reliable system operation. For more information, see the "Configuring System Security" section of the
Cisco MGX 8260 Command Line Interface Guide.

The first step in preparing the Cisco MGX 8260 media gateway for network connectivity is configuring the plug-in cards. For more information, see the "Configuring Cards" section of the Cisco MGX 8260 Command Line Interface Guide.

After the cards are initialized, you can set up trunk and tributary lines. For more information, see "Service Management" chapter of the Cisco MGX 8260 Command Line Interface Guide.

The Cisco MGX 8260 media gateway works in conjunction with an external media gateway controller (MGC) or call agent to set up and clear calls. For more information, see the "Call Control" chapter of the Cisco MGX 8260 Command Line Interface Guide. You should also refer to OEM configuration requirements published by the MGC/call agent supplier.

The MGX 8260 configuration tasks listed above can also be performed from Cisco's WebViewer management interface. For more information, refer to the Cisco MGX 8260 WebViewer Guide.
