Service Egress and Ingress QoS Policies
Quality of Service Guide 307
Description This command defines how packets matching the forwarding class will be mapped to an HSMDA
queue ID. The SAP QoS policies simultaneously support both standard service queue mappings and
ESDMA queue mappings for the same forwarding class and the hsmda node is used to separate the
HSMDA mappings from the standard mappings This allows the same QoS policy to be used on a
standard MDA attached SAP and an HSMDA attached SAP.

Description This command specifies the HSMDA queue mapping for all packets in point-to-point services and
unicast destined packets in multipoint services. Point-to-point services include epipe and other VLL
type services. Multipoint services include IES, VPLS and VPRN services. The queue command does
not apply to multicast, broadcast or unknown unicast packets within multipoint services (the multicast,
broadcast and unknown commands must be used to define the queue mapping for non-unicast packets
within a forwarding class). For Epipe, the queue queue-id mapping applies to all packets, regardless
of the packets destination MAC address.
Each forwarding class has a default queue ID based on the intrinsic hierarchy between the forwarding
classes as represented in Table 30. Executing the queue command within the HSMDA context of a
forwarding class with a different queue ID than the default overrides the default mapping. Multiple
forwarding classes may be mapped to the same HSMDA queue ID.
Table 31 presents the way that packets are mapped to queues based on the type of service and the
various forwarding types.
