High speed flow control

The high speed flow control feature lets you control traffic and avoid congestion on the gigabit full-
duplex link. If the receive port buffer becomes full, the switch issues a flow-control signal to the
device at the other end of the link to suspend transmission. When the receive buffer is no longer full,
the switch issues a signal to resume the transmission. You can set the flow control mode to
Asymmetric or disabled.

autonegotiation, ensure that the other side of
the link is also set for autonegotiation.
