Teleste MPH241 - 802.1 p QoS Configuration; DSCP QoS Configuration

73 MPH200 series video encoders WebUI user manual
You can use the Priority drop-down list to quickly set the values in the
802.1p Conguration table. Select Low to set all values to low priority,
Normal to set all values to normal priority, Medium to set all values to
medium priority, or select High 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 conguration
DSCP (DiffServ/Differentiated Services Code Point) is a six bit eld that
is contained within an IP (TCP or UDP) header. Six bits allows the
DSCP eld to take any value in the range 0...63 inclusive. When QoS
Mode is set to DSCP, the DSCP/DiffServ Conguration table appears
which allows a priority to be set for each of the DSCP values.
You can use the Priority drop-down list to quickly set the values in the
DSCP Conguration table. Select Low to set all values to low priority,
Normal to set all values to normal priority, Medium to set all values to
medium priority, or select High to set all values to high priority. Use
Custom if you want to set each value individually.
When QoS Mode is set to DSCP/
DiffServ, the DSCP Conguration
table appears which allows a
priority to be set for each of the
DSCP/DiffServ values.
When QoS Mode is set to 802.1p,
the 802.1p Conguration table
appears which allows a priority to
be set for each of the eight values.
802.1p conguration
The 802.1p eld is held within the VLAN-tag of a packet. The eld is
three bits long so can hold eight values; 0...7 inclusive. When QoS
Mode is set to 802.1p, the 802.1p Conguration table appears which
allows a priority to be set for each of the eight values.
