HAPTER 15: IP PACKET FILTERING
About IP Packet Filtering
The Cuda 12000 supports packet filtering in the form of access lists. Access
lists allow you to restrict and control IP packet flow over specified cable
interfaces. This control of IP packet transmission restricts network access
from specified users, devices, and applications.
IP packet filtering involves the following steps:
1. Create access lists that define the IP packet filtering criteria using the
access-list command as described in “Creating Access Lists” on
page 331.
2. Apply the access lists to specified interfaces using the access-class
command as described in “Applying Access Lists to Interfaces” on
page 336.
3. Enable IP packet filtering on the specified interface as described in
“Enabling and Disabling IP Packet Filtering,” next.
