QoS Group Marking

You can use QoS group marking to assign packets to a QoS group. The QoS group field is an internal
marking that exists only within the router. You can set this field as packets pass through the fabric of the
router. The router uses the group ID marking to determine how to prioritize packets for transmission.
QoS groups are used as part of QoS policy propagation through the Border Gateway Protocol (QPPB)
and are useful in configurations that support MPLS QoS tunneling modes: short pipe, long pipe, and
uniform pipe.
You can set up to 100 different QoS group markings.

set qos-group Command

To set a quality of service (QoS) group identifier (ID) that can be used later to classify packets, use the
set qos-group command in policy-map class configuration mode. To remove the group ID, use the no
form of this command. By default, this command is disabled; no group ID is specified.

Usage Guidelines for the set qos-group Command

The set qos-group command allows you to associate a group ID with a packet. The group ID can be used
later to classify packets into QoS groups as part of QoS policy propagation through the Border Gateway
Protocol (QPPB). QoS groups are also useful in configurations supporting MPLS QoS tunneling modes:
short pipe, long pipe, and uniform pipe.
A QoS group and discard class are required when the input per-hop behavior (PHB) marking is used for
classifying packets on the output interface
