Managing Network Adapters

Modifying vNIC Properties

	Command or Action	Purpose
Step 26	Server	The number of receive queue resources to allocate. The
	/chassis/adapter/host-eth-if/recv-queue	range is 1 to 256; the default is 4.

#set rq-count count

Step 27	Server	The number of descriptors in the receive queue. The
	/chassis/adapter/host-eth-if/recv-queue	range is 64 to 4094; the default is 512.
	# set rq-ring-size size
Step 28	Server	Exits to the host Ethernet interface command mode.
	/chassis/adapter/host-eth-if/recv-queue
	# exit
Step 29	Server /chassis/adapter/host-eth-if #	Enters transmit queue command mode.
	scope trans-queue
Step 30	Server	The number of transmit queue resources to allocate.
	/chassis/adapter/host-eth-if/trans-queue	The range is 1 to 256; the default is 1.
	# set wq-count count
Step 31	Server	The number of descriptors in the transmit queue. The
	/chassis/adapter/host-eth-if/trans-queue	range is 64 to 4094; the default is 256.
	# set wq-ring-size size
Step 32	Server	Exits to the host Ethernet interface command mode.
	/chassis/adapter/host-eth-if/trans-queue
	# exit
Step 33	Server /chassis/adapter/host-eth-if #	Enters completion queue command mode.
	scope comp-queue

Step 34	Server
	/chassis/adapter/host-eth-if/comp-queue
	# set cq-count count

The number of completion queue resources to allocate. The range is 1 to 512; the default is 5.

In general, the number of completion queues equals the number of transmit queues plus the number of receive queues.

Step 35	Server	Exits to the host Ethernet interface command mode.
	/chassis/adapter/host-eth-if/comp-queue
	# exit
Step 36	Server /chassis/adapter/host-eth-if #	Enters TCP offload command mode.
	scope offload

Step 37	Server
	/chassis/adapter/host-eth-if/offload #
	set tcp-segment-offload {disable
	enable}

Enables or disables TCP Segmentation Offload as follows:

•disable —The CPU segments large TCP packets.

•enable —The CPU sends large TCP packets to the hardware to be segmented. This option may reduce CPU overhead and increase throughput rate. This is the default.

Note This option is also known as Large Send Offload (LSO).
