Auto Nego.:
Show the exchange mode of Ethernet MAC. There are two modes
supported in the switch. They are auto-negotiation mode “Enabled” and
forced mode “Disabled”. When in “Enabled” mode, this function will
automatically negotiate by hardware itself and exchange each other the
capability of speed and duplex mode with other site which is linked, and
comes out the best communication way.
When in “Disabled” mode, both parties must have the same setting of
speed and duplex, otherwise, both of them will not be linked. In this case,
the link result is “Down”.
Default: Enabled
Speed / Duplex :
Display the speed and duplex of all port. There are three speeds 10Mbps,
100Mbps and 1000Mbps supported for TP media, and the duplex
supported is half duplex and full duplex. If the media is 1Gbps fiber, it is
1000Mbps supported only. The status of speed/duplex mode is
determined by 1) the negotiation of both local port and link partner in
“Auto Speed” mode or 2) user setting in “Force” mode. The local port has
to be preset its capability.
In port 1 – 24, they are supported Fast Ethernet with TP media only, so
the result will show 100M/Full or 100M/Half, 10M/Full and 10M/Half
duplex.
In port 25 and port 26, if the media is 1000Mbps with TP/SFP media, it
will show the combinations of 10/100M and Full/Half duplex, 1000Mbps
and Full duplex only. If the media is 1000Mbps with fiber media, it will
show only 1000M/Full duplex.
Default: None, depends on the result of the negotiation.
Rx Pause:
The way that the port adopts to process the PAUSE frame. If it shows
“on”, the port will care the PAUSE frame; otherwise, the port will ignore
the PAUSE frame.
Default: None
Tx Pause:
It decides that whether the port transmits the PAUSE frame or not. If it
shows “on”, the port will send PAUSE frame; otherwise, the port will not
send the PAUSE frame.
Default: None
