Configuring the CMTS
6-37
• You can bundle all cable interfaces into a single bundle to share a single IP
subnet.
The cable bundling feature requires that the following conditions are observed:
• Cable interface bundling is only supported on cable interfaces.
• One cable interface must be configured as the master interface for the bundle. The
other cable interfaces are configured as slave interfaces.
• An IP address is only assigned to master cable interface.
• DHCP relay is only enabled on the master cable interface.
• ARP authorization is enabled on both the master cable interface and the slave
cable interfaces.
• Cable upstream and downstream parameters remain unique for each individual
cable interface.
• Cable interface bundles are configured using CLI commands only.
Creating a Cable Bundle
Follow these steps to configure a cable bundle on the BSR 64000:
1. To enter the cable interface that you want to designate as the master cable
interface, use the interface cable command in Global Configuration mode as
shown below:
MOT(config)#interface cable <x>/<y>
where:
x is the slot number of the cable module.
y is the cable interface number, which is 0.
For example:
MOT(config)#interface cable 4/0
2. To make sure that DHCP relay is enabled on the master cable interface, use the
show running-config command in Privileged EXEC mode. Check the command
output to see if the IP helper address or cable helper address is assigned to the
master cable interface.
