GSM-2116 and GSM-2124
Displays the port number. The number is 1 – 16 or 24. Ports 15 (23) and 16 (24) may be fiber
modules.
Media:
Shows the media type used in all ports. Ports 15 (23) and 16 (24) are optional modules, which
support either fiber or UTP media with either Gigabit Ethernet or Fast Ethernet. They may have
different media types and speed. Since the fiber port could be multimode or singlemode, the
information will be based on the actual media installed in the switch with reference to connector,
distance, fiber mode, etc. The module port information is displayed in Figure 5.11.
Link:
Displays an active or unactive port. If the link is connected to a working device, the link will
show that is it “Up”; otherwise, it will show “Down”. This is determined by the hardware on both
devices of the connection.
No default value.
State:
Displays the communication function of the port is “Enabled” or “Disabled”. When it is enabled,
traffic can be transmitted and received via this port. When it is disabled, no traffic can be
transferred through this port. Port State is configured by user.
Default: Enabled.
Auto Negotiation:
Displays 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 be automatically negotiated by the hardware itself and exchange the
capability of speed and duplex mode. The best communication mode will be used. When in
“Disabled” mode, both parties must have the same setting of speed and duplex, otherwise,
there will be no link. In this case, the link result is “Down”.
Default: Enabled
Speed / Duplex Mode:
Displays the speed and duplex mode of all ports. There are three speeds 10Mbps, 100Mbps
and 1000Mbps supported for TP media. Duplex mode is half duplex and full duplex. If the
media is 1Gbps fiber, it is 1000Mbps only. The status of speed/duplex mode is determined by:
Negotiation of both the local port and the link partner in “Auto Speed” mode
User setting in “Force” mode. The local port has to be preset according to its capability.
Default: None, depends on the result of the negotiation.
Flow Control:
Show each port’s flow control status.
There are two types of flow control in Ethernet,
backpressure
for half-duplex operation and
pause flow control
(IEEE802.3x) for full-duplex operation. The switch supports both.
Default: Disabled
