6 Configure the Operation Modes
there are Routers in the network.
DNS
is used to access other stations by name. The
ConfigPort
is used to access the NetCom
+
for administration via Telnet. It is suggested to use the standard
value for Telnet, TCP port number
23
. However it may be changed for different purposes. This
does not change the function of the Telnet menus.
The firmware can operate each serial port as Print Server. The TCP Port defined by RFC1194
(mostly referred to as »Line Printer Daemon«) is
515
, under certain circumstances you may change
the
PrintServerPort
. More about Print Server function at the configuration of the serial ports
(
6.2.2.2.8 on page 85
).
KeepAlive
is an intrinsic function of the TCP/IP protocol.
If used it causes network traffic,
traditionally intended to prohibit automatic shut-down of Dial-Up network equipment. In a LAN
this traffic usually is not a problem. If this functions is
On
, you must define a
KeepAliveInterval
given in seconds. As a side effect of the traffic network problems are detected earlier. NetCom
+
has a better chance to react on network problems, or failed hosts. Even dropping an old connection
may be useful in certain environments. It is suggested to activate this function when using RAW
TCP communication (
6.2.2.2.2
,
6.2.2.2.3
), with an interval of about 180 seconds.
