dot1p
Syntax dot1p dot1p-priority fc fc-name profile {in | out}
no dot1p
Context config>qos>network>ingress
This command explicitly sets the forwarding class or enqueuing priorityand profile of the packet
Description
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 overridebe assigned to the forwarding class and
enqueuing priorityand 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 SAPsports using the
policy.
dot1p-priority — This value is a required parameter that specifies the unique IEEE 802.1P value that will
Parameters
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 .
A maximum of eight dot1p rules are allowed on a single policy.
Values
fc fc-name — The value given for the fc-name parameter must be one of the predefined forwarding classes
in the system. Specifying the fc-name is optional. When a packet matches the rule, the forwarding class
is only overridden when the fc fc-name parameter is defined on the rule. If the packet matches and the
forwarding class is not explicitly defined in the rule, the forwarding class is inherited based on previous
rule matches.
Values
profile {in | out } — All packets that are assigned to this forwarding class will be considered in or out of
profile based on this command or to use the default. In case of congestion, the in-profile packets are
preferentially queued over the out-of-profile packets.
