show dcb cn q-profile

Use this command to display the congestion notification queue profile configuration stats.

Syntax

show dcb cn q-profile [profile-id]

Parameters

profile-id An integer ID value in dotted notation for this queue profile. Valid values are in dotted notion by index and type. For example, index 0 and queue type 1 would be formatted as 0.1.

Defaults

If profile-id is not specified, all queue profiles are displayed.

Mode

All command modes.

Output... What it displays...
Support Legend Defines acronyms listed in the Support field for this display.
QP Type Specifies a queue type integer value based upon the platform.
Description A queue type description.
Max QP Entries Specifies the maximum number of queue profile entries supported by the device.
Min Weight Specifies the minimum weight value supported by this device.
Max Weight Specifies the maximum weight value supported by this device.
Max Min-Sample Specifies the maximum minimum sample supported by this device.
Support Specifies congestion point queue features supported by this device.
CP Ports Specifies congestion point ports configured on the device.
QP Index An index value for this queue profile.
Set Point A target value for the number of octets in the congestion point queue. CNM PDUs are transmitted to the frame source queued in this congestion point's queue in order to keep the total number of octets stored in the queue at this set point.
Weight (W) W is the weight to be given to the change in queue length in the calculation of quantitized feedback (a measure of transmit queue congestion) as defined in the IEEE 802.1Q-2011 standard.

Weight is an integer value from which W is derived equal to two to the power of the weight value specified here. Thus, if weight equals a -1, W = 1/2. This value can be between the values specified by Min Weight and Max Weight for this device. The default value is 1.

Minimum Sample Base The minimum number of octets to enqueue in the congestion point queue between transmissions of CNM PDUs. The default value is 150000.
Minimum Header Octets The minimum number of octets to be returned in the encapsulated MSDU field of each CNM PDU generated.
