Port security modes
Port security supports the following categories of security mode:
• MAC learning control—Includes autoLearn and secure. MAC address learning is permitted on
ports in autoLearn mode and disabled on ports in secure mode.
• Authentication—Implements MAC authentication, 802.1X authentication, or a combination of the
two authentication methods.
Upon receiving a frame, the port in a security mode searches the MAC address table for the source MAC
address. If a match is found, the port forwards the frame. If no match is found, the port learns the MAC
address or performs authentication, depending on the security mode. If the frame is illegal, the port takes
the pre-defined NTK, intrusion protection, or trapping action.
The maximum number of users a port supports equals the maximum number of MAC addresses that port
security allows or the maximum number of concurrent users the authentication mode in use allows,
whichever is smaller. For example, if 802.1X allows more concurrent users than port security's limit on the
number of MAC addresses on the port in userLoginSecureExt mode, port security's limit takes effect.
