Accessing the G700 Media Gateway processors using a serial connection

This section covers how to access the Layer 2 Switching Processor and G700 Media Gateway Processor over a serial interface. Information includes:

• Hardware and software requirements
• Serial connection login procedure
• Media Gateway Processor (MGP) session

Hardware and software requirements

To successfully establish a serial connection, your computer must have:

• A physical serial connection to the console port of the G700 Media Gateway or Layer 2 Switching Processor.
• A terminal emulation program such as Microsoft Windows� HyperTerminal installed.

  NOTE: Note:

  For a list of CLI commands, see "CLI Command Reference" in the "Maintenance for the AvayaTM G700 Media Gateway controlled by an AvayaTM S8300 Media Server or an AvayaTM S8700 Media Server".

Serial connection login procedure

1. Launch the terminal emulation program for a serial connection on your computer, such as HyperTerminal. If your computer is directly connected to the Console port, access that port. For example, using HyperTerminal, choose Call.
2. When the Login prompt appears, type the appropriate user name (such as cust).
3. When prompted, enter the appropriate password.
4. You are now logged in to the Layer 2 Switching Processor CLI at the Supervisor level. The prompt appears as P330-n(super)# where n indicates the stack number of the master controller device for the stack. If only one device is in the stack, the number appears as P330-1.
5. In order to use the commands necessary to configure the stack processor, you must enter the configuration mode of the CLI. Type configure
6. The prompt now appears as P330-n(configure)#. Enter commands as needed.
• For example, you might type: set interface inband 1 192.168.23.2 255.255.255.0 to assign IP address 192.168.23.2 to the stack processor (the fields before and after it are the VLAN group ID and the subnet mask).
• To check the syntax of a command, type as much of the command as you know followed by help. For example, you could type: set interface help
7. From this interface, you can access the Media Gateway Processor using the session mgp command.

Media Gateway Processor (MGP) session

Once you have logged in to the Layer 2 Switching Processor, you can access the Media Gateway Processor (MGP) using the session mgp command, without having to log in again. From the MGP, you can exit back to the Layer 2 Switching Processor, or you may telnet to the IP address of the S8300 Media Server, if installed).

To session to the MGP from the Layer 2 Switching Processor CLI:

1. You must be logged into the Layer 2 Switching Processor. See Serial connection login procedure.
2. At the P330-n(configure)# prompt, type session <module #> mgp to reach the G700 Media Gateway Processor, where <module #> is the number of the Media Gateway in the stack (default is 1).

NOTE: Note: The module number is not required in a single gateway configuration. It is also not required when the MGP is in the G700 you are currently logged onto (stack master).

3. You are now logged in to the MGP CLI at the view-only level. The prompt appears as MG-???-n(super)# where:
• MG indicates Media Gateway
• ??? indicates the Media Gateway number that is registered with the MultiVantage^TM software. If the Media Gateway has not yet registered with a call-processing server, the number is replaced by question marks.
• n indicates the Media Gateway module number in the stack.
4. In order to use the commands necessary to configure the MGP, you must enter the configuration mode of the CLI. Type configure
5. The prompt now appears as MG-???-n(configure)# (or the equivalent administered name). Enter commands as needed.

For example, you might type a set mgp <vlan> <ip_address> <mask> <gateway> command to assign an IP address to the G700 Media Gateway.

6. When finished, you can access other command line interfaces as follows:
• To exit the MGP CLI and return to the Layer 2 Switching Processor CLI, type exit. The P330-n(configure)# prompt appears.
• To start a telnet session to an S8300 Media Server installed in slot 1 of this Media Gateway, type telnet <ip_address> (see Accessing a CLI using telnet for details about logging in to telnet).
• To start a telnet session to any administered and accessible device in the network, type telnet <ip_address> (see Accessing a CLI using telnet for details).
• Network routing information must be in place for a telnet connection to work.
• Devices can be accessed by IP address only from this interface.
