Congestion Point Queue

The settings for a subset of parameters associated with a congestion point queue can be modified. Congestion point indexes are assigned to congestion point queues which have one or more CNPVs mapped to them on a given port. These congestion queues can be configured using the assigned congestion point index. The congestion point index is one greater than the lowest CNPV which is mapped to the congestion notification queue. For example: if CNPVs 4 and 7 are configured for a transmit queue, the congestion point index is 5. A queue profile which supports the configuring of a minimum sample option can also be associated with the congestion point configuration.

Congestion point queues are configured with the set dcb congestion-point command. You can configure the following:

A maximum of two congestion notification queue profiles can be associated with a congestion point queue configuration. The default queue profile on the S- and 7100-Series has an identifier of 0.1 and can be displayed using the show dcb cn q-profile command. This default queue profile can not be modified. A second queue profile, 1.1, can be configured. The queue profile is configured using the set dcb cn q-profile command. See Congestion Notification Queue Profile for a congestion notification queue profile discussion.

Use the show dcb cn congestion-point command to display congestion point queue information.
