Description This command associates a network Quality of Service (QoS) policy with a network 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.
Associating a network QoS policy with a network interface is useful for the following purposes:
• To apply classification rules for determining the forwarding-class and profile of ingress packets
on the interface.
• To associate ingress packets on the interface with a queue-group instance applied to the ingress
context of the interface’s forwarding plane (FP). (This is only applicable to interfaces on IOM3
and later cards.) The referenced ingress queue-group instance may have policers defined in order
to rate limit ingress traffic on a per-forwarding class (and forwarding type: unicast vs. multicast)
basis.
• To perform 802.1p, DSCP, IP precedence and/or MPLS EXP re-marking of egress packets on the
interface.
• To associate egress packets on the interface with a queue-group instance applied to the egress
context of the interface’s port. The referenced egress queue-group instance may have policers
and/or queues defined in order to rate limit egress traffic on a per-forwarding class basis.
The no form of the command removes the network QoS policy association from the network IP
interface, and the QoS policy reverts to the default.
Default
no qos
Parameters
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 the egress
queue-group used for all egress forwarding-class redirections specified within the network QoS
policy ID. The specified
queue-group-name must exist as an egress queue group applied to the
egress context of the port associated with the IP interface.
egress-instance instance-id — Since multiple instances of the same egress queue-group can be
applied to the same port this optional parameter is used to specify which particular instance to
associate with this particular network IP interface.
Values
1 — 16384
ingress-fp- redirect-group queue-group-name — This optional parameter specifies the ingress
queue-group used for all ingress forwarding-class redirections specified within the network QoS
policy ID. The specified queue-group-name must exist as an ingress queue group applied to the
ingress context of the forwarding plane associated with the IP interface.
ingress-instance instance-id — Since multiple instances of the same ingress queue-group can be
applied to the same forwarding plane this parameter is required to specify which particular
instance to associate with this particular network IP interface.
Values
1 — 16384
