CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Switch Configuration
Configure Port Security Mode Screen
This function disables address learning of source and/or destination addresses at
specified ports on a switch. Port security totally blocks (secures) these addresses.
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 to a specific port, you can block all source addresses at that port and then use
port filtering (as explained in the previous sections of port filtering) to selectively
allow specific addresses to send to that port.
Selecting the Configure Port Security Mode item at the Filter & Port Security
screen, presents a screen with the Configure Port Security table on it, as shown
below.
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.
