Configuring the PA-FE-TX or PA-FE-FX
To continue your PA-FE-TX or PA-FE-FX port adapter installation, you must configure the Fast Ethernet interface. 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
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-FE-TX or PA-FE-FX 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 you plan to route on each new interface
•IP addresses, if you plan to configure the interfaces for IP routing
•Bridging protocols you plan to use
If you installed a new PA-FE-TX or PA-F-FX 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-FE-TX or PA-FE-FX 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-FE-TX or PA-FE-FX, refer to the appropriate configuration publications listed in the "Related Documentation" section on page viii.
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:
•Performing a Basic Configuration
•Configuring PA-FE-TX or PA-FE-FX Transmission Mode
•Configuring PA-FE-TX or PA-FE-FX Media Type
Performing a Basic Configuration
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 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 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 2 The following examples explain how to configure the Fast Ethernet interface:
•For the Cisco 7100 series, Cisco 7200 series, and the Cisco uBR7200 series, at the prompt specify the first interface to configure by entering the subcommand interface, followed by the type (fastethernet) and slot/interface (port adapter slot number and interface number). The example that follows is for the first interface of the port adapter in slot 4:
Router(config)# interface fastethernet 4/0
Note For the Cisco 7206VXR and Cisco 7206 router shelves in the Cisco AS5800 Universal Access Server, the interface specified in the above example would include a shelf number. For example, the command interface fastethernet 5/4/0 would specify the first Fast Ethernet interface of the port adapter in slot 4 of router shelf 5.
•For the Cisco 7301 router, the Cisco 7401ASR router, and the Cisco 7304 PCI Port Adapter Carrier Card in a Cisco 7304 router, at the prompt specify the first interface to configure by entering the subcommand interface, followed by the type (fastethernet) and slot/interface (port adapter slot number and interface number). The example that follows is for the first interface of the port adapter in slot 1:
Router(config)# interface fastethernet 1/0
•For the VIP, at the prompt specify the first interface to configure by entering the subcommand interface, followed by the type (fastethernet) and slot/port-adapter/interface. The example that follows is for the first interface of the first port adapter, on a VIP in interface processor slot 1:
Router(config)# interface fastethernet 1/0/0
•For the Catalyst RSM/VIP2, at the prompt specify the first interface to configure by entering the subcommand interface, followed by the type (fastethernet) and port-adapter/interface. The example that follows is for the first interface of the first port adapter, on a Catalyst RSM/VIP2:
Router(config)# interface fastethernet 0/0
Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to the interface with the ip address configuration 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 Change the shutdown state to up and enable the interface as follows:
Router(config-if)# no shutdown
Step 6 Configure additional interfaces as required.
Step 7 After including all of the configuration commands 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.
Configuring PA-FE-TX or PA-FE-FX Transmission Mode
Half-duplex operation is the default transmission mode for the PA-FE-TX or PA-FE-FX. Use the full-duplex command to configure full-duplex operation for the PA-FE-TX or PA-FE-FX as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#
Router(config)# interface fastethernet 4/0
Router(config-if)# full-duplex
Ctrl-z
Use the show interfaces fastethernet command to verify that the 4/0 Fast Ethernet interface is now configured for full-duplex operation as follows:
Router# show interfaces fastethernet 4/0
FastEthernet 4/0 is administratively up, line protocol is up
(display text omitted)
Encapsulation ARPA, loopback not set, keepalive not set, fdx, 100BaseTX
Use the no full-duplex command to return the interface to half-duplex operation as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface fastethernet 4/0
Router(config-if)# no full-duplex
Ctrl-z
Router#
Use the show interfaces fastethernet command to verify that the 4/0 Fast Ethernet interface is now configured for half-duplex operation as follows:
Router# show interfaces fastethernet 4/0
FastEthernet2/0 is administratively up, line protocol is up
(display text omitted)
Encapsulation ARPA, loopback not set, keepalive not set, hdx, 100BaseTX
(display text omitted)
To check the interface configuration using show commands, proceed to the "Checking the Configuration" section
Note When you enter the show interfaces fastethernet command using Cisco IOS Release 11.1(10) or later, or Release 11.2(4) or later with updated Cisco hardware, the "overrun" field is always zero.
If you use this command because you are troubleshooting potential network problems, you may be expecting to see a number in the overrun field.
Configuring PA-FE-TX or PA-FE-FX Media Type
The RJ-45 receptacle is the default media type for the PA-FE-TX and the SC receptacle (for fiber-optic connections) is the default media type for the PA-FE-FX. Use the media-type mii command to configure the MII receptacle as the media type for the PA-FE as follows:
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# interface fastethernet 4/0
Router(config-if)# media-type mii
Ctrl-z
Router# show interface fastethernet 4/0
FastEthernet3/0/0 is administratively up, line protocol is up
(display text omitted)
Encapsulation ARPA, loopback not set, keepalive not set, hdx, MII
(display text omitted)
Use the media-type 100 command to return the media type for the PA-FE-TX or PA-FE-FX to the RJ-45 receptacle or SC receptacle.
To check the interface configuration using show commands, proceed to the "Checking the Configuration" section.
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 show Commands to Verify the Interface Status
•Using the ping Command to Verify Network Connectivity
Using show Commands to Verify the Interface Status
This section demonstrates how you can use the show commands to verify that interfaces are configured and operating correctly and that the port adapter 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 on page viii.
If an interface is shut down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the interface is properly connected and terminated. If you still have problems bringing up the interface, contact a service representative for assistance. This section includes the following subsections:
•Using the show controllers Commands
•Using the show protocols Command
•Using the show running-config Command
•Using the show startup-config Command
•Using the show version or show hardware Commands
•Using the show interfaces Command
Choose the subsection appropriate for your system. Proceed to the "Using the ping Command to Verify Network Connectivity" section when you have finished using the show commands.

Using the show interfaces Command
The show interfaces command displays status information (including the physical slot and interface address) for the interfaces you specify.
For complete descriptions of interface commands and the configuration options available for specific interfaces, refer to the publications listed in the "Related Documentation" section on page viii.
Note The outputs that appear in this document may not match the output you receive when running these commands. The outputs in this document are examples only.
The following sections offer some platform-specific output examples using the show interfaces command:

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 "Related Documentation" section on page viii 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.
