Priority
IEEE 802.1p defines up to 8 separate traffic classes. This switch
supports Quality of Service (QoS) by using two priority queues,
with Weighted Fair Queuing for each port. You can use the Priority
Menu to configure the default priority for each port, or to display
the mapping for the traffic classes.
Port Priority Configuration
Inbound frames that do not have any VLAN tags are tagged with
the input port's default VLAN ID (PVID) and the default ingress
user priority as shown in the following screen, and then sorted
into the appropriate priority queue at the output port. (Note that if
the output port is an untagged member of the associated VLAN,
these frames are stripped of all VLAN tags prior to transmission.)
The default priority for all ingress ports is zero. Therefore, any
inbound frames that do not have priority tags will be placed in the
low priority queue of the output port. You can use the Port Priority
Configuration screen to adjust default priority for any port as
shown below.
