4. If you selected the Limit security mode, you can set a threshold or
specific limit on the maximum number of dynamic MAC addresses
the port can learn. The threshold is automatically set to 1 until you
change it in the Threshold data entry field. Enter the number of
dynamic MAC addresses (between 1 and 170) you want the port to be
able to learn.
Note
A threshold cannot be set for the port if the Security Mode is set to
Normal or Secure. If a port has Normal or Secure security set, it is
unable to learn dynamic MAC addresses and has a threshold of 0.
5. To control what happens on the port once the threshold has been
met, check one of the radio buttons next to the intrusion detection
notification options.
The notification options are:
No action
Disable the port only
Notify with trap only
Notify with trap and disable the port
6. To configure the security for another port, select the Stack ID and port
number from the pull-down menus at the top of the Port Security
page and repeat this process.
7. To verify the new port security configurations and to see the security
settings for all of the ports at once, continue to the next section:
Displaying Port Security Settings on page 186.
