12. ACL
ACL (Access Control List) is an ordered list of classification filters and actions. Each single classification rule,
together with its action, is called an Access Control Element (ACE). Each ACE is made up of filters that
distinguish traffic groups and associated actions. A single ACL may contain one or more ACEs, which are
matched against the contents of incoming frames. Either a DENY or PERMIT action is applied to frames
whose contents match the filter.
Note
When a packet matches an ACE filter, the ACE action is taken and that ACL processing is
stopped. If the packet does not match the ACE filter, the next ACE is processed. If all ACEs of an
ACL have been processed without finding a match, and if another ACL exists, it is processed in
a similar manner.
If no match is found to any ACE in all relevant ACLs then ACL default action will dropped the packet.
12.1 MAC ACL
This page mainly creates MAC ACLs profile. The MAC ACLs are used to filter traffic based on Layer 2
fields and defined on the MAC ACE page.
Note
A port can be either secured with ACLs or configured with advanced QoS policy, but
not both.
