Establishing Switch Access

This chapter describes various methods for accessing the Avaya P330 CLI and logging in with the appropriate security level.

Methods for accessing the Avaya P330 CLI include using:

• a terminal to the serial port on the switch

• P330 Sessions

• a workstation running a Telnet or SSH session connected via the network

• a remote terminal/workstation attached via a modem (PPP connection)

Establishing a Serial Connection

This section describes the procedure for establishing switch access between a terminal and the Avaya P330 switch over the serial port provided on the front panel of the P330 (RJ-45 connector labeled “Console”). For information on the console port

pin assignments, refer to “Console Pin Assignments“ on page 13.

Configuring the Terminal Serial Port Parameters

The serial port settings for using a terminal or terminal emulator are as follows:

• Baud Rate - 9600 bps

• Data Bits - 8 bits

• Parity - None

• Stop Bit - 1

• Flow Control - None

• Terminal Emulation - VT-100

Connecting a Terminal to the Avaya P330 Serial port

Perform the following steps to connect a terminal to the Avaya P330 Switch Console port for accessing the text-based CLI:

1 The P330 device is supplied with a console cable and a RJ-45-to-DB-9 adaptor.

Use these items to connect the serial (COM) port on your PC/terminal to the

Avaya P330 console port.

2 Ensure that the serial port settings on the terminal are 9600 baud, 8 bits, 1 stop bit and no parity.

3 When you are prompted for a Login Name, enter the default login. The default login is root.

4 When you are promoted for a password, enter the user level password root.

P330 Sessions

You can use sessions to switch between the CLI of P330 modules, other stack entities

(for example, an X330 ATM or WAN entity plugged into a specific P330 switch or with the G700 Media Gateway Processor), or to switch between Layer 2 and Layer 3 commands in the router module.

To switch between P330 modules use the command: session [<mod_num>] <mode>

.

The <mod_num> is the number of the module in the stack, counting from the bottom up.

The <mode> can be either switch, router, wan, atm, mgp.

Use switch mode to configure layer 2 commands.

Use router mode to configure routing commands.

Examples:

To configure router parameters in the module that you are currently logged into, type the following command:

session router

.

To configure the switch parameters, on module 6, type the command:

session 6 switch

.

L When you use the session command the security level stays the same.

Assigning P330’s IP Stack Address

L All P330 switches are shipped with the same default IP address. You must change the IP address of the master P330 switch in a stack in order to guarantee that the stack has its own unique IP address in the network.

The network management station or a workstation running Telnet session can establish communications with the stack once this address had been assigned and the stack has been inserted into the network. Use the CLI to assign the P330 stack an

IP address and net mask.

To assign a P330 IP stack address:

1 Establish a serial connection by connecting a terminal to the Master P330 switch of the stack.

2 When prompted for a Login Name, enter the default name root

3 When you are prompted for a password, enter the password root. You are now in Supervisor Level.

4 At the prompt, type:

set interface inband

<vlan> <ip_address> <netmask>

Replace <vlan>, <ip_address> and <netmask> with the VLAN,

IP address, and net mask of the stack.

5 Press Enter to save the IP address and net mask.

6 At the prompt, type reset and press Enter to reset the stack. After the Reset, log in again as described above.

7 At the prompt, type set ip route <dest> <gateway> and replace <dest> and <gateway> with the destination and gateway IP addresses.

Establishing a Telnet Connection

Perform the following steps to establish a Telnet connection to the Avaya P330 for configuration of Stack or Router parameters. You can Telnet the Stack Master

IP address:

1 Connect your station to the network.

2 Verify that you can communicate with the Avaya P330 using Ping to the IP of the Avaya P330. If there is no response using Ping, check the IP address and default gateway of both the Avaya P330 and the station.

L The Avaya P330 default IP address is 149.49.32.134 and the default subnet mask is 255.255.255.0.

3 From the Microsoft Windows taskbar of your PC click Start and then Run (or from the DOS prompt of your PC), then start the Telnet session by typing:

telnet

<P330_IP_address>

If the IP Address in the Telnet command is the IP address of the stack, then connection is established with the Switch CLI entity of the Master module.

When you see the “Welcome to P330” menu and are prompted for a Login

Name, enter the default name root

4 When you are prompted for a password, enter the User Level password root in lower case letters (do NOT use uppercase letters). The User level prompt will appear when you have established communications with the Avaya P330.

5 Press Enter to save the destination and gateway IP addresses.

Establishing an SSH Connection

Perform the following steps to establish an SSH connection to the Avaya P330 for configuration of Stack or Router parameters. You can open an SSH session to the

Stack Master IP address:

1 Connect your station to the network.

2 Verify that you can communicate with the Avaya P330 using Ping to the IP of the Avaya P330. If there is no response using Ping, check the IP address and default gateway of both the Avaya P330 and the station.

L The Avaya P330 default IP address is 149.49.32.134 and the default subnet mask is 255.255.255.0.

3 Using the show ip ssh command, ensure that an SSH key has been generated on the switch using the crypto key generate dsa command and that SSH is enabled on the switch using the ip ssh enable command.

4 Using your SSH client software, open a session to the Stack Master IP address.

5 When you are prompted for a password, enter the User Level password root in lower case letters (do NOT use uppercase letters). The User level prompt will appear when you have established communications with the Avaya P330.

Establishing a Modem (PPP) Connection with the P330

Overview

Point-to-Point Protocol (PPP) provides a Layer 2 method for transporting multi-protocol datagrams over modem links.

Connecting a Modem to the Console Port

A PPP connection with a modem can be established only after the Avaya P330 is configured with an IP address and net-mask, and the PPP parameters used in the

Avaya P330 are compatible with the modem’s PPP parameters.

1 Connect a terminal to the console port of the Avaya P330 switch as described in

Connecting a Terminal to the Avaya P330 Serial port.

2 When you are prompted for a Login Name, enter the default name root.

3 When you are prompted for a password, enter the password root. You are now in Supervisor Level.

4 At the prompt, type:

set interface ppp

<ip_addr> <net-mask> with an IP address and netmask to be used by the Avaya P330 to connect via its

PPP interface.

L The PPP interface configured with the set interface ppp command must be on a different subnet from the stack inband interface.

5 Set the baud rate, ppp authentication, and ppp time out required to match your modem. These commands are described in the Avaya P330: Reference Guide.

6 At the prompt, type:

set interface ppp enable

The CLI responds with the following:

Entering the Modem mode within 60 seconds...

Please check that the proprietary modem cable is plugged into the console port

7 Use the DB-25 to RJ-45 connector to plug the console cable to the modem’s

DB-25 connector. Plug the other end of the cable RJ-45 connector to the

Avaya P330 console’s RJ-45 port.

8 The Avaya P330 enters modem mode.

9 You can now dial into the switch from a remote station, and open a Telnet session to the PPP interface IP address.

Security Levels

There are four security access levels – User, Privileged, Configure, and Supervisor.

• The User level (‘read-only’) is a general access level used to show system parameter values.

• The Privileged level (‘read-write’) is used by site personnel to access stack configuration options.

• The Configure level is used by site personnel for Layer 3 configuration.

• The Supervisor level (‘administrator’) is used to define user names, passwords, and access levels of up to 10 local CLI users, configure SNMPv3, configure

RADIUS authentication, and control access protocols to the device.

L If you wish to define more than ten users per switch, or accounts for a user on multiple switches, use RADIUS (Remote Authentication Dial-In User Service).

A login name and password are always required to access the CLI and the commands. The login name, password, and access-type (i.e., security level) for a user account are established using the username command.

Switching between the entities, does not effect the security level since security levels are established specifically for each user. For example, if the operator with a privileged security level in the Switch entity switches to the Router entity the privileged security level is retained.

L If you wish to increase security, you can change the default user accounts.

Entering the Supervisor Level

The Supervisor level is the level in which you first enter P330 CLI and establish user names for up to 10 local users. When you enter the Supervisor level, you are asked for a Login name. Type root as the Login name and the default password root

(in lowercase letters):

Welcome to P330

Login: root

Password:****

Password accepted.
