Understanding Interface Configuration

Understanding Interface Configuration
Many features in the software are enabled on a per-interface basis. When you enter the interface
command, you must specify the following information:
•
•
•
You can identify ports from the physical location. You also can use show commands to display
information about a specific port, or all the ports.

Using the Interface Command

You use the commands described in this section to configure both physical ports and logical interfaces.
Note
These procedures apply to all interface configuration processes. Begin the interface configuration
process in global configuration mode. To use the interface command, follow these steps:
Enter the configure terminal command at the privileged EXEC prompt to enter global configuration
Step 1
mode:
Router# configure terminal
Enter configuration commands, one per line.
Router(config)#
In the global configuration mode, enter the interfaces command. Identify the interface type and the
Step 2
number of the connector or interface card.
The following example shows how to select Fast Ethernet, slot 5, interface 1:
Router(config)# interfaces fastethernet 5/1
Router(config-if)#
Enter the show interfaces EXEC command to see a list of all interfaces that are installed. A report is
Step 3
provided for each interface that the device supports, as shown in this display:
Router# show interfaces fastethernet 5/48
FastEthernet5/48 is up, line protocol is up
Hardware is C6k 100Mb 802.3, address is 0050.f0ac.3083 (bia 0050.f0ac.3083)
Internet address is 172.20.52.18/27

Interface type:
Ethernet (use the ethernet keyword)
–
Fast Ethernet (use the fastethernet keyword)
–
Gigabit Ethernet (use the gigabitethernet keyword)
–
10-Gigabit Ethernet (use the tengigabitethernet keyword)
–
For WAN interfaces, refer to the configuration note for the WAN module.
Note
Slot number—The slot in which the module is installed. On the Cisco 7600 series router, slots are
numbered starting with 1, from top to bottom.
Port number—The physical port number on the module. On the Cisco 7600 series router, the port
numbers always begin with 1. When facing the rear of the router, ports are numbered from the left
to the right.
