Configuring Trust Mode for 802.1p Classification (CLI)
To define the trust mode for 802.1p classification, go to interface view for the interface and enter the following
command:
eth type eth [x/x]>classification set 802.1p <802.1p>
Note
If you change the trust mode for DSCP, the trust mode for MPLS is automatically changed to the
same setting.
To display the trust mode for 802.1p classification, go to interface view for the interface and enter the following
command:
eth type eth [x/x]>classification show 802.1p state

Permitted Values
Description
802.1p
Variable
trust
un-trust
Enter the interface's trust mode for user priority
(UP) bits:
trust
– The interface performs QoS and color
classification according to UP and CFI/DEI bits
according to user-configurable tables for 802.1q
UP bits (C-VLAN frames) or 802.1AD UP bits (S-
VLAN frames). VLAN UP bit classification has
priority over DSCP and MPLS classification, so
that if a match is found with the UP bit of the
ingressing frame, DSCP values and MPLS bits are
not considered.
un-trust
– The interface does not consider
802.1 UP bits during classification.
The following command enables 802.1p trust mode for GbE 1:
eth type eth [1/1]>classification set 802.1p trust
The following command disables 802.1p trust mode for GbE 1:
eth type eth [1/1]>classification set 802.1p un-trust
Configuring DSCP Classification (CLI)
When DSCP classification is set to Trust mode, the interface performs QoS and Color classification according to a
user-configurable DSCP to CoS and Color classification table. 802.1p classification has priority over DSCP Trust
Mode, so that if a match is found on the 802.1p level, DSCP is not considered.
