Accessing and Administering the TGM550 CLI

The CLI on the TGM550 allows you to configure, monitor, and diagnose the TGM550 and TIMs installed in a Services Router. You can access the TGM550 from a management device attached to the TGM550 console port or by opening a Telnet or secure shell (SSH) session from the JUNOS CLI on the Services Router.

You can also open a remote Telnet or SSH session directly to the TGM550 from a network location, or indirectly through the JUNOS CLI from a dial-up connection with a USB modem attached to the router. For information about the modem connection, see the J-series Services Router Administration Guide at http://support.avaya.com.

This section contains the following topics. For complete information about the TGM550 CLI, see the Administration Guide and CLI Reference for the Avaya IG550 Integrated Gateway.

TGM550 Access Requirements

Administrators can use the root password to access the TGM550 initially, but all users need a TGM550 user account (username and password) set up by the network administrator for regular access to the module. For information about user accounts on a TGM550, see the Administration Guide and CLI Reference for the Avaya IG550 Integrated Gateway at at http://support.avaya.com.

Note: You cannot use a Services Router user account to access the TGM550 CLI.

• A console connection requires the Ethernet rollover cable and adapter provided with the TGM550. (See Connecting Through the TGM550 Console Port.)
• An SSH connection requires that the TGM550 have an IP address assigned.
• A Telnet connection to the TGM550 requires that the module have an IP address and that Telnet service be enabled on the module.

To assign an IP address to the TGM550, see Configuring VoIP Interfaces with Quick Configuration or Configuring the VoIP Interface (Required).

To enable Telnet, see Accessing the TGM550 with Telnet.

Connecting Through the TGM550 Console Port

To connect to the TGM550 through its console port:

1. Turn off the power to the management device, such as a PC or laptop computer, that you are using to access the TGM550.
2. Plug one end of an Ethernet rollover cable provided with the TGM550 into the RJ-45 to DB-9 serial port adapter provided with the TGM550.

   Caution: Two different RJ-45 cables and RJ-45 to DB-9 adapters are provided. Do not use the RJ-45 cable and adapter for the Services Router console port to connect to the TGM550 console port.

3. Plug the RJ-45 to DB-9 serial port adapter provided with the TGM550 into the serial port on the management device.
4. Connect the other end of the Ethernet rollover cable to the console port (CONSOLE) on the TGM550.
5. Turn on power to the management device.
6. Start your asynchronous terminal emulation application (such as Microsoft Windows Hyper Terminal), and select the appropriate COM port to use (for example, COM1).
7. Configure the port settings as follows:
   • Bits per second: 9600
   • Data bits: 8
   • Parity: None
   • Stop bits: 1
   • Flow control: Hardware
8. At the login prompt, type your username and press Enter.
9. At the password prompt, type your password and press Enter.

Connecting to the TGM550 with SSH

To connect to the TGM550 with SSH:

1. Ensure that the TGM550 has an IP address. (See Configuring VoIP Interfaces with Quick Configuration or Configuring the VoIP Interface (Required).)
2. From the JUNOS CLI or a remote connection, enter the following command:
   
   

   ssh ip-address

Accessing the TGM550 with Telnet

By default, Telnet service is not enabled on the TGM550. You must enable Telnet service on the TGM550 before you can telnet to the TGM550 from other devices or from the TGM550 to other devices.

Caution: Telnet connections are not encrypted and therefore can be intercepted.

This section contains the following topics:

• Enabling Telnet Service on the TGM550
• Connecting to the TGM550 with Telnet
• Disabling Telnet Service on the TGM550

Enabling Telnet Service on the TGM550

To enable Telnet service on the TGM550:

1. Connect to the TGM550 through the console port. (See Connecting Through the TGM550 Console Port.
2. Enable incoming Telnet connections, by entering the following command, replacing port with the Telnet port number:
   
   

   TGM550-004(super)# ip telnet port port
3. Enable outgoing Telnet connections from the TGM550 to other devices, by entering
   
   

   TGM550-004(super)# ip telnet-client
4. Save the configuration by entering:
   
   

   TGM550-004(super)# copy running-config startup-config

Connecting to the TGM550 with Telnet

To connect to the TGM550 with Telnet:

1. Ensure that Telnet is enabled on the TGM550. (See Enabling Telnet Service on the TGM550.)
2. Ensure that the TGM550 has an IP address. (See Configuring VoIP Interfaces with Quick Configuration or Configuring the VoIP Interface (Required).)
3. From the JUNOS CLI or a remote connection, enter the following command:
   
   

   telnet ip-address

Disabling Telnet Service on the TGM550

To disable Telnet service on the TGM550:

1. Connect to the TGM550 through the console port. For more information, see Connecting Through the TGM550 Console Port.
2. Disable incoming Telnet connections, by entering the following command, replacing port with the Telnet port number:
   
   

   TGM550-004(super)# no ip telnet
3. Disable outgoing Telnet connections from the TGM550 to other devices, by entering
   
   

   TGM550-004(super)# no ip telnet-client
4. Save the configuration:
   
   

   TGM550-004(super)# copy running-config startup-config

Accessing the Services Router from the TGM550

You can access the Services Router from the CLI on its installed TGM550 in the following ways:

• Enter the session chassis command.
• Enter the telnet or ssh command.

  Note: Before using the TGM550 CLI telnet command, ensure that Telnet service is enabled on the TGM550. For more information, see Enabling Telnet Service on the TGM550.

Resetting the TGM550

Caution: Before resetting the TGM550, take the following precautions: Log into the TGM550 and enter copy running-config startup-config to save the TGM550 configuration. (For login instructions, see Accessing and Administering the TGM550 CLI.) Ensure that the TGM550 is not currently handling voice traffic.

You can reset the TGM550 from the module itself or from the Services Router.

To reset the TGM550 from the module itself, do one of the following:

• Press the RST button on the TGM550.
• Log into the TGM550, and enter the reset command. (For login instructions, see Accessing and Administering the TGM550 CLI.)

To reset the TGM550 from the device:

1. Enter operational mode in the CLI.
2. Enter the request chassis fpc slot slot-number restart command.

   For example, to reset a TGM550 installed in slot 2 on the router chassis, enter

   
   

   user@host> request chassis fpc slot 2 restart

Note: You cannot reset the TIMs using the request chassis fpc slot slot-number restart command. TIMs are administered only from the TGM550.

Saving the TGM550 Configuration

To save the configuration on the TGM550:

1. Log in to the TGM550. (For login instructions, see Accessing and Administering the TGM550 CLI.)
2. Save the configuration, by entering
   
   

   TGM550-004(super)# copy running-config startup-config
