addresses or configured static MAC addresses. When the number of secure MAC addresses
reaches the upper limit, no more secure MAC addresses can be added.
• Advanced mode—Port security supports 802.1X and MAC authentication. Different port security
modes represent different combinations of the two methods. Table 103 de
scribes the advanced
security modes.
Table 103 Advanced security modes
Advanced mode
MAC-Auth A port performs MAC authentication for users. It services multiple users.
802.1X Port Based
A port performs 802.1X authentication and implements port-based access
control.
In this mode, a port can service multiple 802.1X users. If one 802.1X user passes
authentication, all the other 802.1X users of the port can access the network
without authentication.
In this mode, neither outbound restriction nor intrusion protection will be
triggered.
802.1X Single Host
A port performs 802.1X authentication and implements MAC-based access
control. It services only one user passing 802.1X authentication.
802.1X MAC Based
A port performs 802.1X authentication of users and implements MAC-based
access control. The port in this mode supports multiple online 802.1X users.
802.1X MAC Based Or
OUI
Similar to the 802.1X Single Host mode, a port in this mode performs 802.1X
authentication of users and allows only one 802.1X user to access at a time.
However, in 802.1X MAC Based Or OUI mode:
• The port also permits frames from a wired terminal whose MAC address
contains a specified OUI.
• For frames from a wireless user, the port first performs OUI check. If the OUI
check fails, the port performs 802.1X authentication.
MAC-Auth Or 802.1X
Single Host
This mode is a combination of the 802.1X Single Host and MAC-Auth modes.
802.1X authentication has higher priority.
• For wired users, the port performs MAC authentication upon receiving
non-802.1X frames and performs 802.1X authentication upon receiving
802.1X frames.
• For wireless users, 802.1X authentication is performed first. If 802.1X
authentication fails, MAC authentication is performed.
MAC-Auth Or 802.1X
MAC Based
Similar to the MAC-Auth Or 802.1X Single Host mode, except that it supports
multiple 802.1X and MAC authentication users on the port.
MAC-Auth Else 802.1X
Single Host
This mode is a combination of the MAC-Auth and 802.1X Single Host modes.
MAC authentication has higher priority.
• A port in this mode performs only MAC authentication for non-802.1X frames.
• For 802.1X frames, the port performs MAC authentication and if MAC
authentication fails, it performs 802.1X authentication.
MAC-Auth Else 802.1X
MAC Based
Similar to the MAC-Auth Else 802.1X Single Host mode, except that it supports
multiple 802.1X and MAC authentication users on the port.
The maximum number of users a port supports equals the maximum number of secure MAC addresses or
the maximum number of authenticated users the security mode supports, whichever is smaller.
