Examples

To obtain the receive queue handle, first enter the !ndiskd.netadapter command with no parameters to see the list of net adapters, their drivers, and their handles. In the following example, look for the Microsoft ISATAP Adapter #2's NetAdapter handle, ffff8083e02ce1a0.

3: kd> !ndiskd.netadapter
    Driver             NetAdapter          Name                                 
    ffff8083e2668970   ffff8083e02ce1a0    Microsoft ISATAP Adapter #2
    ffff8083e210fae0   ffff8083e0f501a0    Microsoft Kernel Debug Network Adapter

Next, with the net adapter's handle, use the !ndiskd.netadapter -handle -rcvqueues command to obtain a list of receive queues for this net adapter along with their handles. In this example, there is only one receive queue (the default one) with a handle of ffff8083e3a3d3a0.

3: kd> !ndiskd.netadapter ffff8083e02ce1a0 -rcvqueues


RECEIVE QUEUES

    QueueId            Queue Handle        Processor Affinity                   
    0 [Default]        ffff8083e3a3d3a0    0:0000000000000000 (group:mask)
                       Queue Name:         [Zero-length string]
                       VM Name:            [Zero-length string]

Now you can use the queue handle to examine the receive queue details with the !ndiskd.rcvqueue command.

3: kd> !ndiskd.rcvqueue ffff8083e3a3d3a0
