it receives at this port to a traffic class (see table 47).
Prerequisite:
setting in the Trust Mode column: untrusted or
setting in the Trust Mode column: trustDot1p and the data
packets do not contain a VLAN tag or
setting in Trust Mode column: trustIpDscp and the data packets
are not IP packets.
5.2.2 Selecting the trust mode
The device provides 3 options for selecting how it handles received data
packets that contain priority information. Click once on a cell in the “Trust
