Configuring the number of receive queues on a data plane interface

The number of available receive queues on a data interface depends on the NIC type in the vRouter system. In general, the data plane uses two receive queues. However, a 40 GB device may have four queues. Older devices may have one queue. The following example provides the configuration of the receive queues on a data plane interface by using system interface dataplane <id> rx-queues <number>.

You can enter a number, range separated by a hyphen, or a comma-separated list. You can configure a range if the interface is using multiple queues.
