Classification
15
As shown in the figure, the first criteria considered is whether the packet matches on an ACL that
defines a priority. If this is not the case and the packet is tagged, the packet is classified with the
802.1p CoS value. If neither of these are true, the packet is next classified based on the static
MAC address, ingress port default priority, or the default priority of zero (0).
