Chapter 4: Security
• Port Status: The table has one row for each port on the selected switch and a number of columns, which are:
• Port: The port number for which the status applies. Click the port number to see the status for this particular port.
• Users: Each of the user modules has a column that shows whether that module has enabled Port Security or not. A '-' means
that the corresponding user module is not enabled, whereas a letter indicates that the user module abbreviated by that letter
(see Abbr) has enabled port security.
• State: Shows the current state of the port. It can take one of four values:
- Disabled: No user modules are currently using the Port Security service.
- Ready: The Port Security service is in use by at least one user module, and is awaiting frames from unknown MAC addresses
to arrive.
- Limit Reached: The Port Security service is enabled by at least the Limit Control user module, and that module has indicated
that the limit is reached and no more MAC addresses should be taken in.
- Shutdown: The Port Security service is enabled by at least the Limit Control user module, and that module has indicated that
the limit is exceeded. No MAC addresses can be learned on the port until it is administratively re-opened on the Limit Control
configuration Web page.
• MAC Count (Current, Limit): The two columns indicate the number of currently learned MAC addresses (forwarding as well as
blocked) and the maximum number of MAC addresses that can be learned on the port, respectively.
If no user modules are enabled on the port, the Current column will show a dash (-).
If the Limit Control user module is not enabled on the port, the Limit column will show a dash (—).
Indicates the number of currently learned MAC addresses (forwarding as well as blocked) on the port. If no user modules are
enabled on the port, a dash (—) will be shown.
• Auto-refresh: Check the auto-refresh box to set the unit to refresh information automatically.
• Icon, upper right of screen (Refresh): Click to refresh the Port Security Switch Status information manually.
