source — Enables QoS classification of incoming IP packets based on the source address matching a
route with QoS information.
destination — Enables QoS classification of incoming IP packets based on the destination address
matching a route with QoS information.
qos network-policy-id [egress-port-redirect-group queue-group-name]
no qos
config>router>interface
This command associates a network Quality of Service (QoS) policy with an IP interface. Only one
network QoS policy can be associated with an IP interface at one time. Attempts to associate a
second QoS policy return an error.
Packets are marked using QoS policies on edge devices. Invoking a QoS policy on a network port
allows for the packets that match the policy criteria to be remarked.
The egress-port-redirect-group parameter creates an association between the IP interface and an
egress port queue group. When the network QoS policy ID contains an egress forwarding plane that
is directed to a queue group queue ID, the network QoS policy must be applied to the IP interface
with a valid egress port queue group name. The queue group name must exist on the egress port
associated with the IP interface and the group must contain a queue ID matching the queue ID for
each redirected forwarding class in the QoS policy.
The IP interface may redirect its forwarding classes to a single port queue group. Forwarding classes
that are not redirected to a queue within the group are mapped to the default forwarding class egress
queue on the port.
If the QoS command is re-executed without the egress-port-redirect-group parameter specified, all
forwarding classes will be remapped to the default port forwarding class egress queues.
The no form of the command removes the QoS policy association from the SAP or IP interface, and
the QoS policy reverts to the default.
qos 1 — IP interface associated with network QoS policy 1.
network-policy-id — An existing network policy ID to associate with the IP interface.
Values
1 — 65535
egress-port-redirect-group queue-group-name — This optional parameter specifies that the queue-
group-name will be used for all egress forwarding class redirections within the network QoS
policy ID. The specified queue-group-name must exist as a port egress queue group on the port
associated with the IP interface.
