Chapter2 Configuring the Cable Modem Termination System for the First Time Configuring the CiscouBR10012Router Using the Setup Facility
Configuring interface cable 5/0/0:
Is this interface in use? [yes]:
Configure this interface? [yes]:
IP address for this interface [19.2.22.5]:
Number of bits in subnet field [8]:
Class A network is 19.0.0.0, 8 subnet bits; mask is /16
Configuring interface cable 1/1:
Is this interface in use? [yes]:
Configure this interface? [yes]:
IP address for this interface [19.2.22.6]:
Number of bits in subnet field [8]:
Class A network is 19.0.0.0, 8 subnet bits; mask is /16
The configuration program displays the newly created command interface script:
The following command script was created:
hostname router
enable secret 5 $1$f0fc$A38P/KN/9yD3sEKSt6hKQ/
enable password betty
line vty 0 4
password wilma
snmp-server community public
!
ip routing
!
interface cable 5/0/0
ip address 19.2.22.5 255.255.0.0
router igrp 15
network 19.0.0.0
!
end
Step10 When asked if you want to use this configuration, enter yes or press Return.
Use this configuration? [yes/no]: yes
Step11 Save your settings to NVRAM. (Refer to the Configuring the Cable Interface with the Extended Setup
Facilitysection on page14.)
Note You must always manually save the configuration settings to NVRAM whenever they are modified.
Configuring Upstream Frequencies
Upstream parameters must be configured manually. After the Setup facility is run, upstream ports have
a default state of shutdown.You have two methods to configure upstream channel frequencies:
Configure a fixed frequency between 5 to 42MHz for North American channel plans, and enable
the upstream port.
Create a global spectrum group, assign the interface to it, and enable the upstream port.
The cableinterface card receiver accepts time-division multiplexed burst transmissions from
cableinterfaces (or CMs in set-top boxes), which are DOCSIS-based. The upstream port becomesup
when it is assigned an upstream frequency and is configured to be administratively up.
The upstream port is frequency-agile. The frequency can change while the interface is up and carrying
traffic, if you define spectrum groups per the example provided.
