Note – Precedence Groups are not related to ACL Groups.
The switch processes each precedence group in numeric sequence; Precedence group 1 is evaluated
first, followed by precedence group 2, and so on.
Within each precedence group, ACLs that are assigned to the port are processed in numeric
sequence, based on ACL number. Lower-numbered ACLs take precedence over higher-numbered
ACLs. For example, ACL 1 (if assigned to the port) is evaluated first and has top priority within
precedence group 1.
