CMTS Configuration Guide
7.6
CONFIGURING THE CMTS MODULE
There are two ways to configure the CMTS module for operation, in a routed network and in a bridged network. In the
bridged network the CMTS module and the DHCP server must be on the same VLAN. In the routed network, the
DHCP server can be located on the routed network.
The procedure in this section assume that you have installed the operating software for the system, logged onto the
system, and performed initial system configuration.
7.6.1
Configuring the CMTS Module in a Bridged Network
Before preforming the steps in this example procedure you must set up the DHCP server to assign IP addresses in a
range that is compatible with the VLAN that the CMTS module and the DHCP server are assigned. Prior to performing
this procedure you must also set up the TFTP and DNS servers.
VLANs are used to associate physical ports with connected hosts that need to participate in the same broadcast domain.
To associate ports to a VLAN, you must first create a VLAN and then assign ports to the VLAN.
Configure the CMTS module by entering the following commands:
1.
Create an IP VLAN. In this example the VLAN is named ‘dhcp.’ Create the VLAN by entering:
vlan
create
dhcp
ip
2.
Assign the RS 8000/8600 Ethernet port to the VLAN named ‘dhcp’ by entering:
vlan
add
ports
et.1.1
to
dhcp
3.
Assign the CMTS port to the VLAN named ‘dhcp’ by entering:
vlan
add
ports
cm.7.1
to
dhcp
4.
Create an IP interface called ‘dhcp’ with the address 10.50.86.23 for the VLAN ‘dhcp’ by entering:
interface
create
ip
dhcp
address-netmask
10.50.86.23/16
vlan
dhcp
5.
The
system
set
name
command configures the name of the RS 8000/8600. Name the system
‘CMTS3’ by entering:
system
set
name
CMTS3
6.
The
system
set
timezone
command sets the local time zone. Set the time zone to Pacific Standard
Time using the keyword ‘pst’ by entering:
system
set
timezone
pst
7.
Establish the authorization text string for the CMTS module by entering:
cmts
set
headend
cm.7.1
auth-str
DOCSIS
8.
Enable the upstream channels are necessary. The following command enables upstream channel 1
by entering:
cmts
set
uschannel
cm.7.1
upstream
1
state
on
