Port Security Configuration Window

This window appears when you select ports and click Modify in the Port Security window. Use it to complete the task of enabling port security.

To enable port security and define actions for address violations:

  1. In the Security Status section, select Enable from the list.
  2. In the Violation Action section, take one these actions for Catalyst 2950 and 3550 switches:
    1. Select Shutdown to disable the port if a violation occurs.
    2. Select Restrict to send an alert to the SNMP trap manager.
    3. Select Protect to drop packets with an unknown address if the number of secure addresses for the port reach the maximum allowed.
  3. In the Violation Action section, take one or both of these actions for Catalyst 2900 XL and 3500 XL switches:
    1. Select Enable from the Send Trap menu to send an alert to the SNMP trap manager.
    2. Select Enable from the Shutdown Port menu to disable the port if a violation occurs.
      If you enable Send Trap and Shutdown Port, the switch takes both actions if a violation occurs.
  4. Specify the Maximum Address Count, if necessary.
    Enter a number from the valid range. To guarantee the attached device full port bandwidth, set Maximum Address Count to 1.
    Note: You must enable port security before you can change the Maximum Address Count field.
  5. Click OK to put your changes in effect and to close the window.
