802.1p
Packets are prioritzed using the content of the VLAN-tag. The 802.1p field
is held within the VLAN-tag of a packet. The field is three bits long so can
hold eight values; 0 - 7 inclusive. When QoS Mode is set to 802.1p, the
802.1p Configuration table appears which allows a priority (normal or
high) to be set for each of the eight values.
You can use the Prioritize Traffic drop-down list to quickly set the values
in the 802.1p Configuration table. Select All Normal Priority to set all
values to normal priority or select All High Priority to set all values to high
priority. Use Custom if you want to set each value individually.
Note:
Because end-stations, like PCs, are not usually VLAN aware, they
do not create VLAN-tagged frames. As a result, this method of
prioritization is not ideal when there are a lot of PCs connected to
the switch.
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 inclusive. When QoS Mode is set
to DSCP, the DSCP Configuration table is displayed, which allows a
priority (normal or high) to be set for each of the DSCP values.
You can use the Prioritize Traffic drop-down list to quickly set the values
in the DSCP Configuration table. Select All Normal Priority to set all
values to normal priority or select All High Priority to set all values to high
priority. Use Custom if you want to set each value individually.
