Configuration Commands
Description This command overrides the default HSMDA scheduling policy on the ingress MDA. The command
can only be executed on an MDA provisioned as a HSMDA. Attempting to provision a scheduler
policy on a non-HSMDA will fail. The defined hsmda-scheduler-policy-name must be an existing
HSMDA scheduler policy. An HSMDA scheduler policy that is currently associated with an
HSMDA cannot be removed from the system.
When the scheduler policy is changed on an ingress HSMDA, the ingress scheduling parameters are
immediately changed to reflect the parameters within the policy.
The scheduler policy defined on the ingress context of an HSMDA cannot be changed when local
scheduler overrides exist. The scheduler overrides must be removed prior to changing the scheduler
policy. Once the scheduler policy is changed, any required overrides may be redefined.
The no form of the command restores default HSMDA scheduler policy control over the ingress
scheduler on the HSMDA. The no scheduler-policy command cannot be executed when scheduler
overrides exist on the ingress HSMDA. The overrides must be removed prior to executing the no
scheduler-policy command.

Description This command enables synchronous Ethernet on the MDA. Then any port on the MDA can be used
as a source port in the sync-if-timing configuration.
The no form of the command disables synchronous Ethernet on the MDA.

scheduler-policy context. The "default" policy name cannot be specified. Instead, the no
scheduler-policy command should be executed resulting in the default scheduler policy being
used by the ingress MDA.
