Security Features

The Hub-14 has built-in per-port security. After you have set up security by

clicking on the Security icon, security violations are reported in the Intruder

Log.

You can specify three levels of security on a single port or all ports on the

hub. You can set the hub to learn a port’s authorized MAC address

automatically by either continuous learning or acquiring the first address

heard. Alternatively, you can assign an address directly.

The method used to learn the authorized MAC address should be chosen

based on the level of data security required on a port. For continuous or

first heard methods, the port learns the device’s address from the source

address field in the training packet.

Continuous Method-provides minimum port security. The “continuous”

method allows the hub to continuously update the authorized MAC address

configured for a port. Each new device connected to the port becomes the

new authorized device. This security method is useful for dynamic

workgroups that experience frequent changes to end-user configuration and

require minimal data security protection.

First-Heard Method-provides medium port security. The “first heard”

method automatically assigns the first address detected on the port as the

authorized MAC address. This method is useful to quickly identify and

authorize end users. Under this method, the port will retrain automatically if an

intruder is detected on the port and will not permit an unauthorized end-node to

ever complete training.

Assign an Address-provides the highest security. You can assign an

authorized MAC address by entering it manually at the hub console interface

or at the network management station. Assigning a specific address provides

the maximum control of the port’s authorized MAC address. The security

that you have configured for that port is implemented as soon as the address

is assigned. Again, the port will retrain automatically if an intruder is

detected on the port, and end-nodes other than the authorized one will not

be permitted to complete training.
