no hsmda-slope-policy policy-name
Context config>qos
Description
This command creates an HSMDA RED slope policy. The policy may be assigned to an ingress or
egress HSMDA queue. The policy contains the Maximum Buffer Size (MBS) that will be applied to
the queue and the high and low priority RED slope definitions. The function of the MBS and RED
slopes is to provide congestion control for an HSMDA queue. The MBS parameter defines the
maximum depth a queue may reach when accepting packets. The low and high priority RED slopes
provides for random early detection of congestion and slope based discards based on queue depth.
An HSMDA slope policy can be applied to queues defined in the SAP ingress and SAP egress QoS
policy HSMDA queues context. Once an HSMDA slope policy is applied to a SAP QoS policy queue,
it cannot be deleted. Any edits to the policy are updated to all HSMDA queues indirectly associated
with the policy.
Default HSMDA Slope Policy
An HSMDA slope policy named "default" always exists on the system and does not need to be created.
The default policy is automatically applied to all HSMDA queues unless another HSMDA slope policy
is specified for the queue. The default policy cannot be modified or deleted. Attempting to execute the
no hsmda-slope-policy default command results in an error.
The no form of the command removes the specified HSMDA slope policy from the configuration. If
the HSMDA slope policy is currently associated with an HSMDA queue, the command will fail.
