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.
