QoS Setting
In QoS Mode, select QoS Disabled, 802.1p, or DSCP to configure the related parameters.
QoS Configuration
Strict: Services the egress queues in sequential order, transmitting all traffic in the higher priority queues
before servicing lower priority queues.
WRR: Weighted Round-Robin shares bandwidth at the egress ports by using scheduling weights with
default values of 1, 2, 4, 8 for queues 0 through 7, respectively. (This is the default selection.)
QoS Mode: QoS Disabled
When the QoS Mode is set to QoS Disabled, the following table is displayed.
QoS Mode: 802.1p
Packets are prioritized using the 802.1p field in the VLAN tag. This field is three bits long, representing the values
0 - 7. When the QoS Mode is set to 802.1p, the 802.1p Configuration table appears, allowing you to map each of
the eight 802.1p values to a local priority queue (low, normal, medium or high). The default settings are shown
below.
When the QoS Mode is set to 802.1p, the 802.1p Configuration table is displayed as shown below.
QoS Mode: DSCP
DSCP: Packets are prioritized using the DSCP (Differentiated Services Code Point) value. The Differentiated
Services Code Point (DSCP) is a six-bit field that is contained within an IP (TCP or UDP) header. The six bits
allow the DSCP field to take any value in the range 0 - 63. When QoS Mode is set to DSCP, the DSCP
Note: WRR can only be selected if
is disabled on the Port Configuration page.
