4-28 CHAPTER 4: MANAGING YOUR HUB USING QUICK CONFIG MANAGER

Hub Security

The OfficeConnect Hub 8/TPM provides flexible communication between your workstations and other network equipment. It is a good idea to configure security for the hub to protect your network from unwanted communications.

Security can be performed at two levels:

■Port — Configure security for an individual port.

■Hub — Configure security for one or more ports at a time.

The way you set up your security depends on what you want to do. For example, if you have one device connected to a specific port, you would manage at port level to secure that connection. If you have several devices that you want to connect to any of a number of ports, you would manage at hub level to secure that connection.

If you simply want to disable a port, see “Configuring a Port” on page 4-25.

3Com’s security is very advanced but easy to set up. It works by learning in a number of ways what devices are communicating through its ports. You can configure the hub to react in two ways:

■Disconnect Unknown Device (DUD) — If the hub detects a communication from an unknown device at a port, it can disable that port to prevent further communication.

■Need To Know (NTK) — If a frame is to be forwarded from a port, the destination address of the frame is checked and if it does not match the device learnt for that port, the frame is scrambled to prevent the communication from being intercepted.
