Service SAP QoS Policy Command Reference
The no form of this command is used to restore the mapping of the broadcast forwarding type within
the forwarding class to the default multipoint queue. If all forwarding class forwarding types had been
removed from the default multipoint queue, the queue will not exist on the SAPs or subscribers or
multi-service site associated with the QoS policy and the no broadcast-policer command will cause
the system to attempt to create the default multipoint queue on each object. If the system cannot create
the queue on each instance, the no broadcast-policer command will fail and the broadcast forwarding
type within the forwarding class will continue its mapping to the existing policer-id. If the no
broadcast-policer command results in a policer without any current mappings, the policer will be
removed from the SAPs and subscribers associated with the QoS policy. All statistics associated with
the policer on each SAP and subscriber will be lost.
Parameters policer-id — When the forwarding class broadcast-policer command is executed, a valid
fp-redirect-group — Redirects a forwarding class to a forwarding plane queue-group as
multicast-policer
Syntax multicast-policer policer-id [fp-redirect-group]

Description Within a sap-ingress QoS policy forwarding class context, the multicast-policer command is used to
map packets that match the forwarding class and are considered multicast in nature to the specified
policer-id. The specified policer-id must already exist within the sap-ingress QoS policy. While the
system is determining the forwarding class of a packet, it is also looking up its forwarding destination
based on the ingress service type and the service instance forwarding records. Two basic types of
services support multicast packets; routed services (IES and VPRN) and L2 multipoint services
(VPLS, I-VPLS and B-VPLS). For the routed service types, a multicast packet is destined to an IPv4
or IPv6 multicast address. For the L2 multipoint services, a multicast packet is a packet destined to a
multicast MAC address (multicast bit set in the destination MAC address but not the ff:ff:ff:ff:ff:ff
broadcast address). The VPLS services also support two other multipoint forwarding types (broadcast
and unknown) which are considered separate from the multicast forwarding type.
If ingress forwarding logic has resolved a packet to the multicast forwarding type within the
forwarding class, it will be mapped to either an ingress multipoint queue (using the multicast queue-
id or multicast queue-id group ingress-queue-group commands) or an ingress policer (multicast-
policer policer-id). The multicast and multicast-policer commands within the forwarding class
context are mutually exclusive. By default, the multicast forwarding type is mapped to the SAP ingress
default multipoint queue. If the multicast-policer policer-id command is executed, any previous
policer mapping or queue mapping for the multicast forwarding type within the forwarding class is
overridden if the policer mapping is successful.

policer-id must be specified. The parameter policer-id references a policer-id that has already
been created within the sap-ingress QoS policy.
