however a general issue for network security for which each
customer must find the appropriate solutions.
Ports with special functions
In addition to access over Telnet or Web Based Management,
there are a variety of functions which can be activated over
various TCP or UDP ports. These are shown in the previous
table. Details can be found in the indicated sections of this
manual.
• SNMP
(see section on
SNMP management )
To incorporate the Com-Server into an SNMP-based net-
work management system, parts of the MIB2 are made
read-accessible. This access is protected in that the sys-
tem password must be used as a community string.
• Inventorytool
(see section on
Inventorying via UDP )
Like all intelligent components from W&T, the Com-Servers
can be accessed through the
WuTility tool. Information is
read from UDP port 8513. No writing can be done over
this path.
• Firmware-Update
(see section on
Firmware-Update of the Com-Servers )
Initialization of a firmware update takes place on the sy-
stem password-protected TCP port 8002. Only the opera-
ting system of the Com-Server is updated after a firmware
update. The configuration data (IP address, gateway, serial
parameters, modes, etc.) are retained.
• Reading/writing the configuration data
(see section on Up-/Download of the configuration data )
The WuTility tool as well as a customer’s own applications
can be used to read from and write to Com-Servers. Both
of the TCP ports 8003 and 8004 used for this are protec-
ted by the system password.
