Displays currently actual link rates and duplex
modes on switch ports. "--" is displayed if a
port is not linked.
Three types of duplex modes are available on
Ethernet ports:
Full-duplex: Ports operating in
Full-duplex mode can send and receive
packets concurrently.
Half-duplex: Ports operating in
Half-duplex mode can either send or
receive packets at a given time.
Auto: Auto-negotiation, ports operating in
Auto-negotiation mode determine their
duplex mode through auto-negotiation
with peer ports. By default, Auto
(Auto-negotiation) is enabled for the
Speed/Duplex option.
With flow control enabled on both the switch
and its link partner, the switch, when
encountering congestion, will send flow
control frames to notify the link partner of
such; upon receiving such frames, the link
partner will temporarily stop sending packets
to the switch, thus avoiding packets drop and
ensuring a reliable network. Meanwhile, if a
certain port receives Pause frame, it will also
stop sending packets out.
By default, the flow control feature is
disabled.
Enable/disable selected port(s). A disabled
port cannot forward packets.
By default, all ports are enabled.
Use this option to group ports together to
implement layer-2 data isolation among ports
in an isolated group to, delivering better
security and flexible networking solutions.
Only in 802.1Q VLAN mode can it be
configured. By default, ports are not isolated.
