Key Concepts

The end station stage attempts to determine an end station’s type by performing the following steps:

1Attempting to start a Telnet session with the device and subsequently parse the Login banner if the Telnet service is supported.

2Determining if the node is operating as a file server. This is achieved by attempting to connect to the device via TCP port 2049.

3Determining if the node is operating as a print server. This is achieved by attempting to connect to the device via TCP port 515.

4Using Microsoft Windows API calls to obtain the Windows operating system information, provided the node is a member of domain/workgroup.

Web Type Recognition

Certain 3Com devices have Web (HTTP) management interfaces but do not support SNMP. Some of these devices identify their type using a hidden tag in their home page. For devices that have been recognized as supporting HTTP but not supporting SNMP, 3Com Network Director looks for this tag in order to recognize the device.

DNS Name Resolution

During this stage 3Com Network Director attempts to retrieve a DNS name for each IP address that has been detected. 3Com Network Director uses information from the Windows registry in order to establish potential DNS servers that exist. It then communicates with them directly making DNS queries using UDP.

NBX Phone Detection

This stage obtains detailed information about any Network Branch eXchange (NBX) devices that were discovered as part of the Web Type Recognition Stage.

The Network Discovery wizard allows you to specify the IP addresses of individual NBX call processors (NCPs) on the network, and a separate username/password for each.

This stage is required because the NBX chassis and phones do not support SNMP. Many of the phones will not have IP addresses and consequently will not respond to a ping. The NBX chassis contains a non-visible Web page which 3Com Network Director downloads using HTTP. The page provides 3Com Network Director with a list of phones that are associated
