Configuring the PA-8B-ST


To continue your PA-8B-ST installation, you must configure the BRI interfaces. The instructions that follow apply to all supported platforms. Minor differences between the platforms—with Cisco IOS software commands—are noted.

This chapter contains the following sections:

Using the EXEC Command Interpreter

Configuring the Interfaces

Checking the Configuration

Using the EXEC Command Interpreter

You modify the configuration of your router through the software command interpreter called the EXEC (also called enable mode). You must enter the privileged level of the EXEC command interpreter with the enable command before you can use the configure command to configure a new interface or change the existing configuration of an interface. The system prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket (>). At the console terminal, use the following procedure to enter the privileged level:


Step 1 At the user-level EXEC prompt, enter the enable command. The EXEC prompts you for a privileged-level password as follows:

Router> enable 

Password: 

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.

When you enter the correct password, the system displays the privileged-level system prompt (#):

Router#

To configure the new interfaces, proceed to the "Configuring the Interfaces" section.

Configuring the Interfaces

After you verify that the new PA-8B-ST is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Have the following information available:

Protocols and encapsulations you plan to use on the new interfaces

Protocol-specific information, such as IP addresses if you configure the interfaces for IP routing

ISDN switch type (Table 4-1 lists ISDN service provider switch types)


Note Configuration commands are executed from the privileged level of the EXEC command interpreter, which usually requires password access. Contact your system administrator, if necessary, to obtain access.

If you installed a new PA-8B-ST or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the new interfaces. If you replaced a PA-8B-ST that was previously configured, the system recognizes the new interfaces and brings each of them up in their existing configurations.

For a summary of the configuration options available and instructions for configuring interfaces on a PA-8B-ST, refer to the appropriate configuration publications listed in the

You execute configuration commands from the privileged level of the EXEC command interpreter, which usually requires password access. Contact your system administrator, if necessary, to obtain password access. (See the "Using the EXEC Command Interpreter" section for an explanation of the privileged level of the EXEC.)

This section contains the following subsections:

Shutting Down an Interface

Performing a Basic Interface Configuration

Shutting Down an Interface

Before you remove an interface that you will not replace, or replace port adapters, use the shutdown command to shut down (disable) the interfaces to prevent anomalies when you reinstall the new or reconfigured port adapter. When you shut down an interface, it is designated administratively down in the show command displays.

Follow these steps to shut down an interface:


Step 1 Enter the privileged level of the EXEC command interpreter (also called enable mode). (See the "Using the EXEC Command Interpreter" section for instructions.)

Step 2 At the privileged-level prompt, enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#

Step 3 Shut down interfaces by entering the interface bri subcommand (followed by the interface address of the interface), and then enter the shutdown command.

When you have finished, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter.

Table 4-2 shows the shutdown command syntax for the supported platforms.

Note If you need to shut down additional interfaces, enter the interface bri command (followed by the interface address of the interface) for each of the interfaces on your port adapter. Use the no shutdown command to enable the interface.


Step 4 Write the new configuration to NVRAM as follows:

Router# copy running-config startup-config
[OK]
Router#

The system displays an OK message when the configuration has been stored in NVRAM.

Step 5 Verify that new interfaces are now in the correct state (shut down) using the show interfaces command (followed by the interface type and interface address of the interface) to display the specific interface.

Step 6 Re-enable interfaces by doing the following:

a. Repeat Step 3 to re-enable an interface. Substitute the no shutdown command for the shutdown command.

b. Repeat Step 4 to write the new configuration to memory. Use the copy running-config startup-config command.

c. Repeat Step 5 to verify that the interfaces are in the correct state. Use the show interfaces command followed by the interface type and interface address of the interface.


For complete descriptions of software configuration commands, refer to the publications listed in the

Performing a Basic Interface Configuration

Following are instructions for a basic configuration, which include enabling an interface and specifying IP routing. You might also need to enter other configuration subcommands, depending on the requirements for your system configuration and the protocols you plan to route on the interface. For complete descriptions of configuration subcommands and the configuration options available for BRI interfaces, refer to the appropriate software documentation.

In the following procedure, press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:

Router# disable

Router> 


Step 1 Enter configuration mode and specify that the console terminal is the source of the configuration subcommands, as follows:

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#

Step 2 Identify the ISDN switch type. In the following example, the switch basic-net3 (a switch for the European Union) is identified as the switch type:

Router(config)# isdn switch-type basic-net3

Note The ISDN switch type that you identify is for all ISDN interface ports installed in the router.


Step 3 Specify the first interface to configure by entering the interface bri subcommand, followed by the interface address of the interface you plan to configure.

Table 4-4 provides examples of the interface bri subcommand for the supported platforms.

interface-port-number)

The example is for the first interface of a
port adapter in port adapter slot 1.

Router(config)# interface bri 1/0
Router(config-if)#

Step 4 Assign an IP address and subnet mask to the interface (if IP routing is enabled on the system) by using the ip address subcommand, as in the following example:

Router(config-if)# ip address 10.0.0.0 10.255.255.255 

Step 5 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.

Step 6 Re-enable the interfaces using the no shutdown command. (See the "Shutting Down an Interface" section.)

Step 7 Configure all additional port adapter interfaces as required.

Step 8 After including all of the configuration subcommands to complete your configuration, press Ctrl-Z—hold down the Control key while you press Z—or enter end or exit to exit configuration mode and return to the EXEC command interpreter prompt.

Step 9 Write the new configuration to NVRAM as follows:

Router# copy running-config startup-config
[OK]
Router#

This completes the procedure for creating a basic configuration.

Checking the Configuration

After configuring the new interface, use the show commands to display the status of the new interface or all interfaces, and use the ping command to check connectivity. This section includes the following subsections:

Using the ping Command to Verify Network Connectivity

Using the ping command, you can verify that an interface port is functioning properly. This section provides a brief description of this command. Refer to the publications listed in the

The ping command sends echo request packets out to a remote device at an IP address that you specify. After sending an echo request, the system waits a specified time for the remote device to reply. Each echo reply is displayed as an exclamation point (!) on the console terminal; each request that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate a bad connection.

Following is an example of a successful ping command to a remote server with the address 10.0.0.10:

Router# ping 10.0.0.10 <Return>
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echoes to 10.0.0.10, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms
Router#

If the connection fails, verify that you have the correct IP address for the destination and that the device is active (powered on), and repeat the ping command.
