HAPTER 14: 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:
■ Creating access lists to define the IP packet filtering criteria.
■ Applying the access lists to specified interfaces.
■ Enabling IP packet filtering on specified interfaces.
Before You Begin
Before you configure IP Packet Filtering, navigate to Network Browser >
GroupName > ChassisName > Cuda Chassis Manager > Configuration >
IP > IP Packet Filtering
Enabling and Disabling IP Packet Filtering
When you apply an access-list to an interface, IP filtering is automatically
enabled. For each interface, you can enable filtering on incoming and
outgoing packets.
Disabling IP filtering means that all packets are permitted to cross the
interface. IP filtering is not automatically disabled when access lists are
removed. You must disable access lists manually.
To enable or disable IP filtering, follow this procedure:
1. In the IP Packet Filtering window, click the Interface Configuration tab.
2. Click the Interface Summary tab. The Interface Summary window
appears.
3. Select the row that includes the interface you wish to enable or disable
for IP Packet Filtering.
4. Select or clear the Filter In or Filter Out check boxes to enable or disable
IP Packet Filtering.
5. Click Apply to commit the changes or click Reset to return the
parameters to the previous values.
