PTP 850 performs the classification on each frame ingressing the system via the logical interface. Classification is
performed step by step from the highest priority to the lowest priority classification method. Once a match is
found, the classifier determines the CoS and Color decision for the frame for the logical interface-level.
For example, if the frame is an untagged IP Ethernet frame, a match will not be found until the third priority level
(DSCP). The CoS and Color values defined for the frame’s DSCP value will be applied to the frame.
You can disable some of these classification methods by configuring them as un-trusted. For example, if 802.1p
classification is configured as un-trusted for a specific interface, the classification mechanism does not perform
classification by UP bits. This is useful, for example, if classification is based on DSCP priority bits.
If no match is found at the logical interface level, the default CoS is applied to incoming frames at this level. In this
case, the Color of the frame is assumed to be Green.
Configuring VLAN Classification and Override (CLI)
You can specify a specific CoS and Color for a specific VLAN ID. In the case of double-tagged frames, the match
must be with the frame’s outer VLAN. Permitted values are CoS 0 to 7 and Color Green or Yellow per VLAN ID. This
is the highest classification priority on the logical interface level, and overrides any other classification criteria at
the logical interface level.
To configure CoS and Color override based on VLAN ID, go to interface view for the interface and enter the
following command:
eth type eth [x/x]>vlan-cos-override set outer-vlan-id <outer-vlan-id>
inner-vlan-id <inner-vlan-id> use-cos <use-cos> use-color <use-color>
To display configured VLAN-based CoS and Color override values, go to interface view for the interface and enter
the following command:
eth type eth [x/x]>vlan-cos-override show outer-vlan-id <outer-vlan-id>
inner-vlan-id <inner-vlan-id>
To delete a set of VLAN-based CoS and Color override values, go to interface view for the interface and enter the
following command:
eth type eth [x/x]>vlan-cos-override delete outer-vlan-id <outer-vlan-id>
inner-vlan-id <inner-vlan-id>

VLAN Classification and Override CLI Parameters
Parameter Input Type Permitted Values Description
outer-vlan-id Number 1 – 4094 (except
4092, which is
reserved for the
default management
service) For double-tagged frames, the S-VLAN
value mapped to the CoS and Color values
defined in the command.
For single-tagged frames, the VLAN value
mapped to the CoS and Color values
defined in the command.
