To obtain a handle for a NETTXQUEUE or NETRXQUEUE, follow these steps:

1. Run the !ndiskd.netadapter extension.
2. Click on the handle for a NetAdapter that has a NetAdapterCx driver installed.
3. Click the "More Information" link to the right of the NetAdapter's NETADAPTER object to run the !ndiskd.cxadapter extension.
4. Enter the !ndiskd.cxadapter command with the -datapath parameter to see that NETADAPTER's datapath queues.

For details on this procedure, see the examples on the !ndiskd.cxadapter topic. In the following example, look for the handle for this NETADAPTER's NETTXQUEUE, ffffd1022f512700.
