4.4.11 Configure Port Security

Figure 40 illustrates the Configure Port Security default screen for an 8-port switch

where each port has its security disabled. (The screens for 16- and 24-port models

would function the same — but display more ports.) If security is enabled for a port, no

further MAC addresses are learned for that port and future transmissions through the

port will only succeed if the destination is listed in the address look-up table. Because

static MAC addresses are not learned (aged out of the table), they are not affected by

the applied security. A convenient link to Add Static MAC Addresses is provided at

the bottom of the screen.

This is a useful feature when connecting to an unknown network — such as connecting

the office network to the control network — and can be used to limit the office devices

that can access the control network.
