To continue your PA 4E port adapter installation, you must configure the 4E interfaces. The instructions that follow apply to all supported platforms. Minor differences between the platforms---with Cisco IOS software commands---are note.d This chapter contains the following sections:
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:
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.
After you verify that the new PA-4E is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Have the following information available:
If you installed a new PA-4E 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-4E that was previously configured, the system recognizes the new interfaces and brings each of them up in their existing configuration.
For a summary of the configuration options available and instructions for configuring interfaces on a PA-4E, refer to the appropriate publications listed in the "Related Documentation" section.
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:
 |
Note The 4E interfaces can be configured at 10 Mbps, half duplex (HDX), for a maximum aggregate bandwidth of 40 Mbps. |
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 interface processor. 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 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 ethernet subcommand (followed by the interface address of the interface), and then enter the shutdown command. Table 4-1 shows the command syntax.
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.

|
Note If you need to shut down additional interfaces, enter the interface ethernet 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. Table 4-2 provides examples.
| Platform | Command | Example |
|---|---|---|
Catalyst RSM/VIP2 in Catalyst 5000 family switches | show interfaces ethernet, followed by slot/port (port-adapter-slot-number/ interface-port-number) | The example is for interface 0 on a port adapter in port adapter slot 1.

Router# show interfaces ethernet 1/1/0 Ethernet 1/1/0 is administratively down, line protocol is down [Additional display text omitted from this example] |
Step 6 Reenable interfaces by doing the following:
a. Repeat Step 3 to reenable 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 "Related Documentation" section.
Following are instructions for a basic configuration: 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 ethernet 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>
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)#
Step 2 Specify the first interface to configure by entering the interface ethernet subcommand, followed by the interface address of the interface you plan to configure. Table 4-3 gives examples.
| Platform | Command | Example |
|---|---|---|
Catalyst RSM/VIP2 in Catalyst 5000 family switches | interface ethernet, followed by slot/port (port-adapter-slot-number/ interface-port-number) | The example is for the first interface of a port adapter in port adapter slot 0. Router(config)# interface ethernet 0/0 Router(config-if)# |
Cisco 7120 series routers
| interface ethernet, followed by slot/port (port-adapter-slot-number/ interface-port-number) | The example is for the first interface of a port adapter in port adapter slot 3. Router(config)# interface ethernet 3/0 Router(config-if)# |
Cisco 7140 series routers
| interface ethernet, followed by slot/port (port-adapter-slot-number/ interface-port-number) | The example is for the first interface of a port adapter in port adapter slot 4. Router(config)# interface ethernet 4/0 Router(config-if)# |
Cisco 7200 series routers | interface ethernet, followed by slot/port (port-adapter-slot-number/ | The example is for the first interface of a Router(config)# interface ethernet 6/0 Router(config-if)# |
Cisco uBR7223 router | interface ethernet, followed by slot/port (port-adapter-slot-number/ | The example is for the first interface of a Router(config)# interface ethernet 1/0 Router(config-if)# |
Cisco uBR7246 and Cisco uBR7246 VXR routers | interface ethernet, followed by slot/port (port-adapter-slot-number/ | The example is for the first interface of a Router(config)# interface ethernet 2/0 Router(config-if)# |
VIP2 in Cisco 7000 series or Cisco 7500 series routers | interface ethernet, followed by slot/port adapter/port (interface-processor-slot-number/ | The example is for the first interface of a Router(config)# interface ethernet 1/1/0 Router(config-if)# |
Step 3 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 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics.
Step 5 Reenable the interfaces using the no shutdown command. (See the "Shutting Down an Interface" section.)
Step 6 Configure all additional port adapter interfaces as required.
Step 7 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 8 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.
After configuring the new interface, use the show commands to display the status of the new interface or all interfaces, and use the ping and loopback commands to check connectivity. This section includes the following subsections:
Table 4-4 demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the PA-4E appears in them correctly. Sample displays of the output of selected show commands appear in the sections that follow. For complete command descriptions and examples, refer to the publications listed in the "Related Documentation" section.

Proceed to the section "Using the ping Command to Verify Network Connectivity" to check network connectivity of the PA-4E and switch or router.
The ping command allows you to verify that an interface port is functioning properly. This section provides brief descriptions of this command. Refer to the publications listed in the "Related Documentation" section for detailed command descriptions and examples.
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.
Proceed to the next section, "Using loopback Commands" to finish checking network connectivity.
With the loopback test, you can detect and isolate equipment malfunctions by testing the connection between the PA-4E interface and a remote device such as a modem or a CSU/DSU. The loopback subcommand places an interface in loopback mode, which enables test packets that are generated from the ping command to loop through a remote device or compact serial cable. If the packets complete the loop, the connection is good. If not, you can isolate a fault to the remote device or compact serial cable in the path of the loopback test.
Depending on the mode of the port, issuing the loopback command checks the following path:
