IP Inbound Traffic Filters
Inbound traffic filters act on packets arriving at an IP interface. Most sites use IP
inbound traffic filters primarily for security, to restrict access to nodes in a
network.
You can use IP inbound traffic filters to accept, prioritize, or drop inbound data
traffic to:
• Reduce network congestion by allowing data packets, frames, and datagrams
to be intercepted and either forwarded or dropped based on predetermined or
user-defined criteria.
• Control access to network resources. For example, you can block traffic from
a specific source by filtering on network address.
Each IP inbound traffic filter has the following properties:
• A unique name, preferably one that identifies its function
• An optional traffic filter template that defines the traffic filter’s configuration
• An optional filter precedence value
You create inbound traffic filters at the IP interface level. Optionally, you can
apply a traffic filter template to it. If you create a traffic filter without applying a
filter template, you must manually configure the traffic filter as described in
“Creating a Traffic Filter Without Using a Filter Template” on page 8-22
.
You can apply a traffic filter template to an inbound IP traffic filter at any time.
However, if the traffic filter contains match criteria information, you must delete
this information before you can apply the traffic filter template.
