To continue your PA-FE-TX or PA-FE-FX port adapter installation, you must configure the 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:
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-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:
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.
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:
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>
To do a basic configuration procedure follow these steps:
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:
Router(config)# interface fastethernet 4/0
 |
Note For the Cisco 7206VXR and Cisco 7206 router shelves, 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 FE interface of the port adapter in slot 4 of router shelf 5. |
Router(config)# interface fastethernet 1/0/0
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-int)# 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-int)# no shutdown
Step 6 Configure additional interfaces as required.
Step 7 When you have included all of the configuration subcommands to complete the configuration, press Ctrl-Z to exit configuration mode.
Step 8 Write the new configuration to nonvolatile memory as follows:
Router# copy running-config startup-config [OK] Router#
This completes the procedure for creating a basic configuration.
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 older, or Release 11.2(4) or older 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. |
The RJ-45 receptacle is the default media type for 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.
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 4-1 demonstrates how you can use the show commands to verify that new interfaces are configured and operating correctly and that the PA-FE-TX or PA-FE-FX 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 next section, "Using the ping Command to Verify Network Connectivity," to check network connectivity of the PA-FE-TX or PA-FE-FX and switch or router.
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 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.
