 Speed/Duplex
 Flow control.
Parameter description:
State:
The communication capability of the port is Enabled or Disabled. When enabled, traffic can be
transmitted and received via this port. When disabled, the port is blocked and no traffic can be
transmitted through this port. Port State is configurable by the user. If you set a port’s state to
Disable, then that port cannot pass traffic, even though Link is displayed.
Default: Enable.
Speed/Duplex:
Set the speed and duplex mode for the port. 10/100Mbps is available for ports 1-24, and
1000Mbps is available for ports 25 and 26. If the media is 1Gbps fiber, it will always be
1000Mbps and the duplex mode can only be full. If the media is TP, the speed/duplex mode is
comprised of speeds of 10/100/1000Mbps and the duplex mode is either full or half duplex. The
following table summarizes the function the media:
Media type NWay Speed Duplex
100M TP ON/OFF 10/100M Full/Half
1000M TP ON/OFF 10/100/1000M Full for all, Half for 10/100
1000M Fiber ON/OFF 1000M Full
Table 5.2
In auto-negotiation mode, there is no default value. In forced mode, the default value depends
on the setting.
Flow Control:
There are two modes to choose in flow control, including Symmetric and Asymmetric. If flow
control is set to Symmetric, both parties can send the PAUSE frame to the transmitting
device(s) in case the receiving port is too busy to handle the packets. When set to
Asymmetric, ?????
.
Default: Symmetric.
5.8.3 Simple Counter
The function of the Simple Counter is to collect information and provide counting about the
traffic of the port, whether the packet is good or bad.
In Figure 5.13, the screen shows all ports’ counter information at the same time. Each data field
is 20-digits. If the counting overflows, the counter will be reset and restart counting. The data is
updated based on the time interval defined by the user. The valid range is three to ten seconds.
The refresh interval is used to set the update frequency. Default update time is three seconds.
