Security ACL Filters

A security ACL filters packets to restrict or permit network traffic. These
filters can then be mapped by name to authenticated users, ports, VLANs,
virtual ports, or Distributed MAPs. You can also assign a class-of-service
(CoS) level that marks the packets matching the filter for priority
handling.

A security ACL contains an ordered list of rules called access control
entries (ACEs), which specify how to handle packets. An ACE contains an
action that can deny the traffic, permit the traffic, or permit the traffic
and apply to it a specific CoS level of packet handling. The filter can
include source and destination IP address information along with other
Layer 3 and Layer 4 parameters. Action is taken only if the packet
matches the filter.
