Setting the port security mode
After enabling port security, you can change the port security mode of a port only when the port is
operating in noRestrictions (the default) mode. To change the port security mode for a port in any other
mode, first use the undo port-security port-mode command to restore the default port security mode.
You can specify a port security mode when port security is disabled, but your configuration cannot take
effect.
You cannot change the port security mode of a port when online users are present.
Configuration prerequisites
Before you set a port security mode for a port, complete the following tasks:
• Disable 802.1X and MAC authentication.
• Check that the port does not belong to any aggregation group.
• If you are configuring the autoLearn mode, set port security's limit on the number of MAC addresses.
You cannot change the setting when the port is operating in autoLearn mode.
