Table 1 describes the significant fields shown in the display.

		Table 1	show controllers cpuctrl cdma channel Field Descriptions
		Field		Description
		DMA queue		Identifies the DMA1 queue.
		Channel		Identifies the channel whose DMA queue is displayed. 0 is the
				ingress channel, and 1 is the egress channel
		queue		Identifies the queue.
		state		Current state of the queue.
		OS Interrupt Level		Current interrupt level for the queue.
		Cpuctrl Interrupt Level		Current interrupt level for the CPU controller.
		OS Run Priority		Run priority level for this queue.
		client handle		Internal identifier for the Cisco client.
		ISR context		Internal information about the location of the ISR2 pointer.
		Pakman/Bufman Instance		Internal information about the location of the Pakman and Bufman
				Instance.
		client callback function pointer		Internal information about the client callback function pointer.
		cleanup function		Internal information about the client cleanup function pointer.
		Queue Created 1 times		Number of times this queue was regenerated.
		Pakmode		Information about internal data structures and parameters.
		Pollflags		Specifies whether the CDMA queue uses a polling or
				interrupt-driven approach for detecting CDMA operation
				completion notification.
				Note Currently, CDMA queues use interrupt driven completion
				only. PDMA queues use interrupt-driven and polling
				completion.
		Total DMA transactions		Number of DMA transactions in the queue.
		Queue create count		Number of times this queue was regenerated.
		DMA transactions		Number of DMA transactions in the queue.
		Bytes transferred		Number of bytes that have been transferred by the Division
				Multiplex Access engine.
		DMA Out of Desc errs		Number of DMA errors in the queue.
		CDMA transactions		Number of CDMA transactions in the queue.
		DMA IWA		Number of IWA bytes that have been processed by the Division
				Multiplex Access engine.
		DMA transaction errs		Number of DMA transactions that had errors.
		Descriptor list base addr		Internal information about the location of the descriptor list.
		Physical address		Physical address of the CPU memory that holds the descriptors in
				the ring used by the CDMA queue hardware.
		list_size		Total number of descriptors in the ring used by the CDMA queue
				hardware.
