4.3.11 Configure Port Security

Figure 39 illustrates an example of the Configure Port Security screen for an 8-port

switch. Each port has its security disabled by default. 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 source 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. Screens for 16- and 24-port switches would display the applicable

number of ports for configuration.

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.

A convenient link to Add Static MAC Addresses is provided at the bottom of the

screen. When activated, this link displays the same screen as shown in Figure 18.
