SmartStack STS16-20D/STS16-20R Token Ring Switches Installation and User Guide Switch Configuration
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.
