​

The Port QoS Trust feature restricts which packet QoS information may be used to determine inbound queue servicing and any priority information to be permitted into the local hop.

Port QoS Trust Mode configuration allows preservation or removal of the inbound QoS priorities carried in Layer 2 (the VLAN cos or Priority CodePoint (PCP) value, known as the 802.1p priority tag) and/or in Layer 3 (the IP-ToS byte, in IP-Precedence or IP-Diffserv mode). The different modes let the customer trust all, some, or no packet priority fields.

The per-port configuration enables the customer to trust some sources or devices and not others. This feature is mutually exclusive with any active port-priority configuration.
