Figure 2-1 Configuring the Trust Mode and Port to 802.1p Mapping
Follow these steps to configure the parameters of the port priority:
1) Select the desired ports, specify the 802.1p priority and set the trust mode as
Untrusted.
802.1p Priority Specify the port to 802.1p mapping for the desired port. The ingress packets from
one port are first mapped to 802.1p priority based on the port to 802.1p mapping,
then to TC queues based on the 802.1p to queue mapping. The untagged packets
from one port will be added an 802.1p priority value according to the port to
802.1p priority mapping.
Trust Mode Select the Trust mode as Untrusted. In this mode, the packets will be processed
according to the port priority configuration.
2) Click Apply.
