# Classification

Configuration > Classification

Traffic classification is done by means of creating Access Control Lists (ACLs). Each ACL consists of an ordered set of Access Control Entries (ACEs). Each ACE specifies classification criteria, a marking rule, and policing rules.

QoS compares received traffic to the ACEs in ACLs until a match occurs. When the traffic matches the classification criteria in an ACE, QoS marks and polices the packet as specified in the ACE and makes no further comparisons.

Three type of ACLs are supported: IP, IPX, and MAC.
