TCP speed and duplex. You can change the speed and duplex of an interface. If you change these
settings, you must ensure that both sides of the NIC cable are configured in the same manner. For
example, if the storage system is set for Auto/Auto, the switch must be set the same. For more
information about TCP speed and duplex settings, see
“Managing settings on network interfaces”
(page 47) .
Frame size. The frame size specifies the size of data packets that are transferred over the network.
The default Ethernet standard frame size is 1500 bytes. The maximum allowed frame size is 9000
bytes.
Increasing the frame size improves data transfer speed by allowing larger packets to be transferred
over the network and by decreasing the CPU processing time required to transfer data. However,
increasing the frame size requires that routers, switches, and other devices on your network support
that frame size.
For more information about setting a frame size that corresponds to the frame size used by routers,
switches, and other devices on your network, see
“Changing NIC frame size” (page 49) .
