Observing System Startup andPerforming a Basic Configuration 4-21
Configuring the Cisco 12008
Note The sample configuration dialog in this section continues the script displayed when
you used the setup facility or the setup command in establishing the system’s global
parameters (see the section entitled “Configuring Global Parameters”). The output shown
in this section is only an example; your configuration dialog might be different, depending
on how you configure your router.
To configure the Ethernet interfaces on the RP and the network interfaces for the installed
line cards, perform the following steps:
Step1 Configure the RP Ethernet interfaces.
The RJ-45 and MII receptacles on the faceplate of the GRP are IEEE 802.3u-
compliant interfaces. The RJ-45 receptacles on the faceplate of the PRP are
IEEE 802.3u-compliant interfaces. These IEEE interfaces provide connectivity
to Ethernet networks.
In the following example, the system is being configured for an Ethernet
interface that will use the IP network layer protocol. (The Ethernet interface does
not support external routing functions.)
In the following configuration dialog, respond to the queries according to your
own configuration requirements. Use your IP address and subnet mask in
responding to the setup prompts.
Configuring interface Ethernet0:
Is this interface in use?: yes
Configure IP on this interface?: yes
IP address for this interface: 3.3.1.1
Number of bits in subnet field: 8
Class A network is 3.0.0.0, 8 subnet bits; mask is 255.255.0.0
Configure CLNS on this interface?: yes
Step2 Configure the line card interfaces.
The Packet-Over-SONET (POS) line card interfaces enable connections to be
made to external OC-3/STM-1 or OC-12/STM-4 networks.
In the following sample configuration dialog for a Quad OC-3c POS line card,
respond to the queries according to your configuration requirements. Use your
IP address and subnet mask in responding to the setup prompts.
