VLAN
(VLAN Priority only) QoS traffic prioritization is applied based on the priority bits in the LAN
ingress packet’s VLAN tag.
PT (Port Priority only) QoS traffic prioritization is applied based on LAN ingress traffic port.
VLAN&Port
(VLAN and Port Priority) In this mode, if the LAN ingress packet contains a VLAN tag, it will
then apply the VLAN Priority scheme; otherwise it applies the port-based priority scheme.
When you select Port (only) or VLAN&Port, the display updates to include Port Priority on the
bottom line:
L2 QoS=Port only (Off,VLAN,PT,VLAN&Port)
Port Priority: P1:1 P2:2 P3:1 P4:1 ()
