Enabling port security
Before you enable port security, disable 802.1X and MAC authentication globally.
When port security is enabled, you cannot enable 802.1X or MAC authentication, or change the access
control mode or port authorization state. The port security automatically modifies these settings in
different security modes.
To enable port security:

port-security enable Port security is disabled.
You can use the undo port-security enable command to disable port security. Because it logs off the
online users, make sure no online users are present.
Enabling or disabling port security resets the following security settings to the default:
• 802.1X access control mode is MAC-based.
• 802.1X port authorization state is auto.
For more information about 802.1X authentication and MAC authentication configuration, see
"Configuring 802.1X" and "Configuring MAC authentication."
Setting port security's limit on the number of secure
MAC addresses on a port
You can set the maximum number of secure MAC addresses that port security allows on a port for the
following purposes:
• Controlling the number of concurrent users on the port. For a port operating in a security mode that
performs MAC authentication, 802.1X authentication, or both, the maximum number of concurrent
users on the port equals this limit or the limit of the authentication mode in use, whichever is smaller.
• Controlling the number of secure MAC addresses on the port in autoLearn mode.
The port security's limit on the number of secure MAC addresses on a port is independent of the MAC
learning limit described in MAC address table configuration in Layer 2—LAN Switching Configuration
Guide.
