Configure Port Security Mode Screen

This function disables address learning of source and/or destination addresses at specified ports on an SmartStack STS16-20D/STS16-20R. Port security totally blocks (secures) these ports. Port security mode is used in conjunction with port filtering. Configure a port security mode on a port and then use “allow” filters to selectively control traffic through that port.

For instance, if you only want one or some small number of addresses to be able to send from a specific port, you can block all source addresses by secure source at that port and then use port filtering (as explained in the previous sections) to selectively allow specific addresses to send from that port.

There are four address security choices:

•

•

•

•

Normal—No security mode is defined for a port. This is the default.

Secure source addresses—Block all source addresses, except those allowed by a configured filter.

Secure destination addresses—Block all destination addresses, except those allowed by a configured filter.

Secure both source and destination addresses—Block all source and destination addresses, except those allowed or forced by a configured filter.

To open this screen from the main menu, select Configuration → Filters & Port

Security. Then select Configure Port Security Mode...
