7.6.2 Configuring the CMTS Module in a Routed Network
The example procedure in this section shows configuring the CMTS to operate in a routed 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.
1. The
vlan create
command creates a VLAN definition. In the following command a port-based
VLAN is created. A port-based VLAN supports IP, SNA, DECnet, IPv6, Appletalk, SNA and Other
protocols. To create a port-based VLAN definition, enter:
vlan create cmts port-based
2. Create an IP VLAN. In this example the VLAN is named ‘dhcp.’ Create the VLAN by entering:
vlan create dhcp ip
3. Assign the RS 8000/8600 Ethernet port to the VLAN named ‘dhcp’ by entering:
vlan add ports et.1.1 to dhcp
4. Assign the CMTS port to the VLAN named ‘cmts’ by entering:
vlan add ports cm.7.1 to cmts
5. Create an IP interface called ‘dhcp’ with the address 10.50.86.23 for the VLAN ‘dhcp’ by entering:
interface create ip dhcp address-mask 10.50.86.23/16 vlan dhcp
6. Create an IP interface called ‘cmts’ with the address 50.3.1.1 for the VLAN ‘cmts’ by entering:
interface create ip cmts address-netmask 50.3.1.1/16 vlan cmt
s
7. You can configure the RS 8000/8600 system to forward UDP broadcast packets received on a given
interface to all other interface by entering.
ip helper-address interface cmts all-interfaces
8. The
system set name
command configures the name of the RS 8000/8600. Name the system
‘CMTS3’ by entering:
system set name CMTS3
9. 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
10. Establish the authorization text string for the CMTS module by entering:
cmts set headend cm.7.1 auth-str DOCSIS
11. Enable the upstream by entering the following command:
cmts set uschannel cm.7.1 upstream all state on
