max-rate
Syntax max-rate rate
no max-rate
Context config>port>ethernet>hsmda
Description This command overrides the max-rate parameters configured in the hsmda-scheduler-policy
associated with the egress port or ingress MDA. When a max-rate is defined at the override level, the
HSMDA scheduler policy’s max-rate parameter is ignored.
The hsmda-scheduler-override max-rate command supports a max parameter that allows the
override command to restore the default of not having a rate limit on the port scheduler. This is
helpful when the HSMDA scheduler policy has an explicit maximum rate defined and it is desirable
to remove this limit at the port instance.
The no form of the command removes the maximum rate override from the egress port or the ingress
MDA scheduler context. Once removed, the max-rate parameter from the HSMDA scheduler policy
associated with the port or MDA will be used by the local scheduler context.
Parameters rate — The rate parameter is mutually exclusive to specifying the max keyword. When executing
the max-rate override command either the keyword max or a rate in megabits-per-second must
be specified.
Values 1 — 40000000, max (Mbps)
max — The max keyword is mutually exclusive to specifying a rate in megabits-per-second. When
executing the max-rate override command either the keyword max or a rate in megabits-per-
second must be specified. The max keyword removes an existing rate limit from the HSMDA
scheduler context.
scheduling-class
Syntax scheduling-class class rate rate
scheduling-class class weight weight-in-group
no scheduling-class class
Context config>port>ethernet>hsmda
Description This command overrides the maximum rate allowed for a scheduling class or the weight of the class
within a weighted scheduling group. The scheduling-class override cannot be used to change
scheduling class weighted group membership; weighted group membership may only be defined
within the HSMDA scheduling policy.
Scheduling classes correspond directly to the queue-IDs used by every queue on an HSMDA. All
queues with an ID of 1 associated with the scheduler are members of scheduling class 1 on the
scheduler. Queues with an ID of 2 are members of scheduling class 2. This is true through scheduling
class 8.
When the scheduling class is not a member of a weighted group, the scheduling-class command may
be used to modify the maximum rate allowed for the scheduling class. This is done using the rate
parameter followed by either the max keyword or an actual rate defined as megabits-per-second. Use
