IP Router Configuration
Router Configuration Guide 185
The functionality enabled by the qos-route-lookup command can be applied to IPv4 packets or IPv6
packets on an interface, depending on whether it is present at the interface context (applies to IPv4) or
the interface>ipv6 context (applies to IPv6). Subscriber management group interfaces for the 7750 SR
and 7450 ESS also do not support the source QPPB option.
The no form of the command reverts to the default.
Default destination
Parameters 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.

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.
