Context

Description
Platforms Supported: 7210 SAS-K.
This command is used to enable DEI based classification. When enabled, the packet classified to
this FC the DEI bit is used to determine the ingress profile for the packet. Packets received with
DEI bit set to zero are treated as in-profile and packets with DEI bit set to one are treated as out-of-
profile packets.
When DEI based classification is enabled, it overrules the profile values specified in the
classification entry used to assign the FC.
The no form of the command disables use of DEI bit for classification of packets.

config>qos>network>ingress
Context
Description
This command explicitly sets the forwarding class or enqueuing priorityand profile of the packet
when a packet is marked with a dot1p-priority specified. Adding a dot1p rule on the policy forces
packets that match the dot1p-priority specified to be assigned to the forwarding class and profile
of the packet based on the parameters included in the Dot1p rule.
The dot1p-priority is derived from the most significant three bits in the IEEE 802.1Q or IEEE
802.1P header. The three dot1p bits define 8 Class-of-Service (CoS) values commonly used to
map packets to per-hop Quality-of-Service (QoS) behavior.
The no form of this command removes the explicit dot1p classification rule from the policy.
Removing the rule on the policy immediately removes the rule on all ingress ports using the
policy.
Parameters
dot1p-priority — This value is a required parameter that specifies the unique IEEE 802.1P value that will
match the dot1p rule. If the command is executed multiple times with the same dot1p-value, the
previous forwarding class is completely overridden by the new parameters .
