■ MAC Address Security: Using Port Security, you can configure each
switch port with a unique list of up to eight MAC addresses for devices
that are authorized to access the network through that port. For more
information, refer to the chapter titled “Configuring and Monitoring
Port Security” in the Access Security Guide for your switch.
■ Username/Password Security: If you are connecting a device that
allows you to enter a username and password that is forwarded to a
networked server for authentication, then you can also configure the
following security features:
– TACACS+
– RADIUS Authentication and Accounting
– 802.1X Authentication
For more information, refer to the Access Security Guide for your switch.
