5.5 Traffic criteria
Go to Configuration > Ethernet > QoS > Traffic Criteria page to set the Traffic Criteria. The Port
and VLAN priority 802.1p are the default traffic criteria for tagged traffic and untagged traffic. And
they cannot be disabled. The IPv4 DSCP can be enabled if it is necessary, and it is prior to other cri-
teria if the DSCP-802.1p mapping was configured in the list. Default setting is with IPv4 DSCP crite-
ria disabled with the exclusion of the VLAN priority 802.1p and Port criteria that is always enabled.

5.6 IP priority
Go to Configuration > Ethernet > QoS > IP Priority page to set the IP Priority. Frames whose Diff-
Serv or TC Priority does not belong to any entry of the IPv4 DSCP priority table and which are
tagged will be processed using VLAN PRI 802.1p priority, or which are untagged will be processed
using Port criteria. Up to 64 values (between 0 and 63) can be configured by NMS.
