HSMDA Command Reference
HSMDA Scheduler QoS Policy Commands
hsmda-scheduler-policy
Syntax hsmda-scheduler-policy scheduler-policy-name [create]
no hsmda-scheduler-policy scheduler-policy-name
Context config>qos
Description
This command configures HSMDA scheduler policy parameters. HSMDA scheduler policies can be
assigned to an egress HSMDA port or as the ingress control scheduler between the HSMDA and the
ingress forwarding plane. The policy contains commands to provision the scheduling behavior of a set
of HSMDA scheduler classes. When assigned to an HSMDA egress port, the policy defines the
scheduling behavior for all queues associated with the egress port. When assigned to the ingress path
of an ESDMA, the policy defines the scheduling behavior for all ingress queues on the HSMDA
(regardless of ingress port).
Up to 1000 HSMDA scheduler policies can be configured per system
The no form of the command removes an HSMDA scheduler policy from the system. If the policy is
associated with an egress port or ingress HSMDA, the command will fail.
Default none
Parameters scheduler-policy-name — Each HSMDA scheduler policy must be uniquely named within the
create — The create keyword is required when the create command is enabled in the
group
Syntax group group-id rate rate
no group group-id
Context config>qos>hsmda-scheduler-policy
Description This command defines the maximum rate allowed for the scheduling classes mapped to the specified
group-id. A group is a scheduling entity used to combine up to three consecutive scheduling classes
into a single strict priority level. Each scheduling class within the group has an associated weight.
When the scheduler is operating at the strict level associated with the group, the ratio of bandwidth
allocated to each scheduling class within the group during congestion at that strict level is relative to
the ratio of the weight of each member. The bandwidth is allocated in a work conserving fashion and
is sensitive to packet size up to the maximum rate defined for the group.

system. Names of up to 32 ASCII characters are supported with the normal character
restrictions. An HSMDA scheduler policy must be defined prior to applying the policy name
to an HSMDA egress port or to an ingress HSMDA.
environment context to create a new HSMDA scheduler policy. This keyword is not required
when the protection is disabled. The keyword is ignored when the HSMDA scheduler policy
already exists.
