28 Ethernet Interface Processor (EIP) Installation and Conﬁguration

Conﬁguring the Interfaces

The following steps describe a basic conﬁguration. Press the Return key after each conﬁguration step

unless otherwise noted.

Step 1 At the privileged-level prompt, enter the conﬁguration mode and specify that the console

terminal will be 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 prompt, specify the ﬁrst interface to conﬁgure by entering the subcommand

interface, followed by the type (ethernet) and slot/port (interface processor slot number

0). The example that follows is for the ﬁrst port on an EIP in interface processor slot 1 (see

Figure 15):

Router(config)# interface ethernet 1/0

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 145.22.4.67 255.255.255.0

Step 4 Add any additional conﬁguration subcommands required to enable routing protocols and

adjust the interface characteristics.

Step 5 Change the shutdown state to up and enable the interface as follows:

Router(config-int)# no shutdown

Step 6 Repeat steps 2 through 4 for each new interface.

Step 7 When you have included all of the conﬁguration subcommands to complete the

conﬁguration, press Ctrl-z (hold down the Control key while you press z) to exit the

conﬁguration mode.

Router(config-int)# ^Z

Step 8 Write the new conﬁguration to memory as follows:

Router# copy running-config startup-config

[OK]

Router#

Step 9 Exit the privileged level and return to the user level by entering disable at the prompt as

follows:

Router# disable
