Using Configuration Mode to Configure an Ethernet Interface
To perform a basic configuration of an Ethernet interface in configuration mode,
follow these steps:
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
At the configuration mode prompt, specify the Ethernet interface by entering the
subcommand
interface
, followed by the
type
(
ethernet
)
and
port
(
0
) as follows:
Router(config)#
interface ethernet 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-int)#
ip address 1.1.1.10 255.255.255.0
Step 4
Add any additional configuration subcommands required to enable or disable
routing protocols (such as the
no ip mroute-cache
command)
and to set other
interface characteristics.
Step 5
Change the shutdown state to Up and enable the Ethernet interface as follows:
Router(config-int)#
no shutdown
Step 6
After you include all the configuration subcommands necessary to complete the
configuration, press
Ctrl-Z
to exit configuration mode.
Step 7
Write the new configuration to nonvolatile memory as follows:
Router#
write memory
[OK]
Router#
