the network. Only then is the address removed. The address is not
timed out, even if the end node becomes inactive.

Note

End users of port-based access control should be instructed to
always log off when they are finished with a work session. This
prevents unauthorized individuals from accessing the network
through unattended network workstations.

ˆ

You cannot use the MAC address port security feature, described in
Chapter 27, “Port Security” on page 637, on switch ports that are set to
the authenticator or supplicant role. A port’s MAC address security
level must be Automatic.

ˆ

There should be only one port in the authenticator role between a
client and the authentication server.

ˆ

A switch port in the authenticator role transmits broadcast and
multicast traffic even when the client connected to the port has not
logged on.

ˆ

An authenticator port can be tagged or untagged.

ˆ

Set ports used to interconnect switches to the none role. This is
illustrated in Figure 235.
