PurposeCommand or Action
The number of receive queue resources to allocate. The
range is 1 to 256; the default is 4.
Server
/chassis/adapter/host-eth-if/recv-queue
# set rq-count count
Step 26
The number of descriptors in the receive queue. The
range is 64 to 4094; the default is 512.
Server
/chassis/adapter/host-eth-if/recv-queue
# set rq-ring-size size
Step 27
Exits to the host Ethernet interface command mode.Server
/chassis/adapter/host-eth-if/recv-queue
# exit
Step 28
Enters transmit queue command mode.Server /chassis/adapter/host-eth-if #
scope trans-queue
Step 29
The number of transmit queue resources to allocate.
The range is 1 to 256; the default is 1.
Server
/chassis/adapter/host-eth-if/trans-queue
# set wq-count count
Step 30
The number of descriptors in the transmit queue. The
range is 64 to 4094; the default is 256.
Server
/chassis/adapter/host-eth-if/trans-queue
# set wq-ring-size size
Step 31
Exits to the host Ethernet interface command mode.Server
/chassis/adapter/host-eth-if/trans-queue
# exit
Step 32
Enters completion queue command mode.Server /chassis/adapter/host-eth-if #
scope comp-queue
Step 33
The number of completion queue resources to allocate.
The range is 1 to 512; the default is 5.
Server
/chassis/adapter/host-eth-if/comp-queue
# set cq-count count
Step 34
In general, the number of completion queues equals the
number of transmit queues plus the number of receive
queues.
Exits to the host Ethernet interface command mode.Server
/chassis/adapter/host-eth-if/comp-queue
# exit
Step 35
Enters TCP offload command mode.Server /chassis/adapter/host-eth-if #
scope offload
Step 36
Enables or disables TCP Segmentation Offload as
follows:
Server
/chassis/adapter/host-eth-if/offload #
set tcp-segment-offload {disable |
enable}
Step 37
• 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.
This option is also known as Large Send
Offload (LSO).
