Setting the Port
Security Mode
With port security enabled, more than one authenticated user is allowed on a
port. The number of authenticated users allowed, however, cannot exceed the
specified upper limited.
By setting the maximum number of secure MAC addresses allowed on a port, you
can
Control the maximum number of users who are allowed access the network
■
through the port
Control the number of secure MAC addresses that can be added with port
■
security
This configuration is different from that of the maximum number of MAC
addresses that can be leaned by the port in MAC address management.
Follow these steps to set the maximum number of secure MAC addresses allowed
on a port:
To do...

Before setting the port security mode, ensure that:
802.1x is disabled, the port access control method is macbased, and the port
■
access control mode is auto.
MAC authentication is disabled.
■
Otherwise, you will see an error message and your configuration will fail.
On the other hand, after setting the port security mode on a port, you cannot
change any of the above configurations.
n
With port security disabled, you can configure the port security mode but your
■
configuration does not take effect.
With port security enabled, you can change the port security mode of a port
■
only when the port is operating in noRestrictions mode, the default mode. You
can use the undo port-security port-mode command to restore the default
port security mode.
You cannot change the port security mode of a port when any user is present
■
on the port.
Configuration of port security mode and aggregation are mutually exclusive.
