Layer 3/4 Priority Settings
– 244 –
Setting Priority
Processing to IP
Precedence/
DSCP or CoS
The switch allows a choice between using IP Precedence, DSCP or CoS priority
processing methods. Use the Priority > Trust Mode page to select the required
processing method.
Command Usage
◆ If the QoS mapping mode is set to IP Precedence, and the ingress packet type is
IPv4, then priority processing will be based on the IP Precedence value in the
ingress packet.
◆ If the QoS mapping mode is set to DSCP, and the ingress packet type is IPv4,
then priority processing will be based on the DSCP value in the ingress packet.
◆ If the QoS mapping mode is set to either IP Precedence or DSCP, and a non-IP
packet is received, the packet’s CoS and CFI (Canonical Format Indicator) values
are used for priority processing if the packet is tagged. For an untagged packet,
the default port priority (see page 237) is used for priority processing.
◆ If the QoS mapping mode is set to CoS, and the ingress packet type is IPv4, then
priority processing will be based on the CoS and CFI values in the ingress
packet.
For an untagged packet, the default port priority (see page 237) is used for
priority processing.
Parameters
These parameters are displayed:
◆ Port – Port identifier. (Range: 1-28)
◆ Trust Mode
■
IP Precedence – Maps layer 3/4 priorities using IP Precedence values.
■
CoS – Maps layer 3/4 priorities using Class of Service values. (This is the
default setting.)
■
DSCP – Maps layer 3/4 priorities using Differentiated Services Code Point
values.
Web Interface
To configure the trust mode:
1. Click Traffic, Priority, Trust Mode.
2. Set the trust mode for any port.
3. Click Apply.
