9.2 SNMP monitoring
The NK823x units can support the SNMP protocol (Simple Network Management
Protocol) to enable remote stations to monitor the units for conditions that may require
administrative attention.
Using the SNMPv1 (RFC 1155-1157) on the UDP port 161, the NK823x provides two
sets of internal information variables using the community IDs listed here below that
enable the access to the MIB (Management Information Base) namespace.
 Public, providing a basic set of information
 Engineer, providing the access to the complete set of information
WARNING
The NK823x built-in firewall closes by default the SNMP port. To enable the SNMP
protocol, select the snmp check box in the Firewall tab.
Note: The event-based notifications (trap) is not supported.
9.3 The NK8000 maintenance and diagnostic tool
There are two maintenance and diagnostic applications available for NK8000
networks. One application (or tool), the NW8204 tool, is contained in the DMS8000
DVD. The other, the NK8000 Web Server tool, is available via Internet Explorer.
Note: The Web Server tool is available for NS8210 only. Use NW8204 (and/or
Composer-based monitoring tools) for NS8011 BACnet/IP driver.
Both tools have the same NW8204 functionalities.
Note: There are slight differences in the NW8204 graphic user interface (installed vs.
Web).
In addition to the NW8204 tool, the NK8000 Web Server tool provides NS8210 and
NK82xx diagnostic utilities. To the end user these tools appear to function in the same
way, however there are important differences:
 NW8204 is a password-protected Windows application that runs on a central
server, and can be installed on a networked PC. It offers maximum security,
whenever this may be matter of concern.
 Web services, available for the central NS8210 driver, can offer a web browser
access, available anywhere on the network with no need of installing any software.
This approach, which requires the network connection, is faster and easier.
Although the access to the web application requires a password, the security is
inferior to the one assured by the NW8204 application (see Launching the NK8000

rver [➙ 79] about IIS security issues).
