All Gigabit Ethernet ports use auto negotiation. If auto negotiation is not set on a
Gigabit Ethernet port, that port uses the full-duplex mode and operates at 1000 Mbps.

Note: If you select an operating mode or speed, the setting disables autodetection
for that parameter on the port. For example, if you set the speed of a segment
to 10 Mbps, that segment no longer uses autodetection for the port speed and
will always attempt to operate at 10 Mbps.

Set the Layer 2 hash mode for all ports. The hash mode controls the distribution of
flow entries in Layer-2 and Layer-3 lookup tables. Assuming a MAC address of the
value 0011:2233:4455, the following list describes the various hash modes.
