To continue your GEIP+ installation, you must configure the Gigabit Ethernet (GE) interface.
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 interface, proceed to the "Configuring the Interface" section.
After you verify that the new GEIP+ is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interface. Have the following information available:
If you installed a new GEIP+ or if you want to change the configuration of an existing interface, you must enter configuration mode to configure the new interface. If you replaced a GEIP+ that was previously configured, the system recognizes the new interface and brings it up in its existing configuration.
For a summary of the configuration options available and instructions for configuring the interface on a GEIP+, 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 subsection:
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 Gigabit 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 gigabitethernet subcommand followed by the interface address of the interface you plan to configure. Table 5-1 provides an example.
| Platform | Command | Example |
|---|---|---|
GEIP+ in Cisco 7500 series routers | interface gigabitethernet, followed by slot/port adapter/port (interface-processor-slot-number/ | The example is for a GEIP+ in interface processor slot 1. Router(config)# interface gigabitethernet 1/0/0 Router(config-if)# |
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 10.1.1.10 255.255.255.255
Step 4 Add any additional configuration subcommands required to enable routing protocols and set the interface characteristics for your configuration requirements.
 |
Note Full-duplex operation is the default for the GEIP+. Half-duplex operation is not supported. |
Step 5 Reenable the interface using the no shutdown command.
Step 6 After including all 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.
Step 7 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 and use the ping command to check connectivity. This section includes the following subsections:
Table 5-2 demonstrates how you can use the show commands to verify that the new interface is configured and operating correctly and that the GEIP+ appears in it 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.

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:
Proceed to the "Using the ping Command to Verify Network Connectivity" section when you have finished using the show commands.
Display the configuration of the system hardware, the number of each interface type installed, the Cisco IOS software version, the names and sources of configuration files, and the boot images, using the show version (or show hardware) command.

The packet internet groper (ping) command allows you to 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.
