Duplex Mode
The twisted pair ports can operate in either half- or full-duplex mode at
10 Mbps or 100 Mbps and full-duplex only at higher speeds.
The duplex mode of a port operating at 10 Mbps or 100Mbps, like port
speed, can be set manually using the management software or
automatically with Auto-Negotiation (IEEE 802.3u), the default setting.
The speed and duplex mode settings of a port can be set independently of
each other. For example in the case of a 10Mbps or 100Mbps port, it can
be configured such that its speed is set manually while its duplex mode is
established through Auto-Negotiation.
