Ethernet Port Commands
Values
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
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
