Refer to the exhibit. What can be determined about port security from the information that is shown?
- The port has been shut down.
- The port has two attached devices.
- The port violation mode is the default for any port that has port security enabled.
- The port has the maximum number of MAC addresses that is supported by a Layer 2 switch port which is configured for port security.
| Answers Explanation & Hints:
The Port Security line simply shows a state of Enabled if the switchport port-security command (with no options) has been entered for a particular switch port. If a port security violation had occurred, a different error message appears such as Secure-shutdown . The maximum number of MAC addresses supported is 50. The Maximum MAC Addresses line is used to show how many MAC addresses can be learned (2 in this case). The Sticky MAC Addresses line shows that only one device has been attached and learned automatically by the switch. This configuration could be used when a port is shared by two cubicle-sharing personnel who bring in separate laptops. |
