Controlling MAC address learning
•
autoLearn
A port in this mode can learn MAC addresses, and allows frames from learned or configured
MAC addresses to pass. The automatically learned MAC addresses are secure MAC addresses.
You can also configure secure MAC addresses by using the
port-security mac-address security
command. A secure MAC address never ages out by default.
When the number of secure MAC addresses reaches the upper limit, the port transitions to secure
mode.
The dynamic MAC address learning function in MAC address management is disabled on ports
operating in autoLearn mode, but you can configure MAC addresses by using the
mac-address
dynamic
and
mac-address static
commands.
•
secure
MAC address learning is disabled on a port in secure mode. You configure MAC addresses by
using the
mac-address static
and
mac-address dynamic
commands. For more information about
configuring MAC address table entries, see
Layer 2—LAN Switching Configuration Guide
.
A port in secure mode allows only frames sourced from secure MAC addresses and manually
configured MAC addresses to pass.
Performing 802.1X authentication
•
userLogin
A port in this mode performs 802.1X authentication and implements port-based access control.
The 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.
•
userLoginSecure
A port in this mode performs 802.1X authentication and implements MAC-based access control.
The port services only one user passing 802.1X authentication.
•
userLoginSecureExt
This mode is similar to the userLoginSecure mode except that this mode supports multiple online
802.1X users.
•
userLoginWithOUI
This mode is similar to the userLoginSecure mode. The difference is that a port in this mode also
permits frames from one user whose MAC address contains a specific organizationally unique
identifier (OUI).
For wired users, the port performs 802.1X authentication upon receiving 802.1X frames, and
performs OUI check upon receiving non-802.1X frames.
Performing MAC authentication
macAddressWithRadius: A port in this mode performs MAC authentication and services multiple users.
Performing a combination of MAC authentication and 802.1X authentication
•
macAddressOrUserLoginSecure
This mode is the combination of the macAddressWithRadius and userLoginSecure modes.
For wired users, the port performs MAC authentication upon receiving non-802.1X frames and
performs 802.1X authentication upon receiving 802.1X frames.
