Enabling port security
When port security is enabled, you cannot manually 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.
Before you enable port security, disable 802.1X and MAC authentication globally.
To enable port security:
Ste

Command
Remarks
1. Enter system view.

2. Enable port security.
port-security enable
By default, port security is disabled.
You can use the undo port-security enable command to disable port security when 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, and the port authorization state is auto.
• Port security mode is noRestrictions.
For more information about Configuring 802.1X, see "Configuring 802.1X."
For more information about MAC authentication configuration, see "Configuring MAC authentication."
Setting port security's limit on the number of MAC
addresses on a port
You can set the maximum number of MAC addresses that port security allows on a port for the following
purposes:
• Controlling the number of concurrent users on the port. The maximum number of concurrent users on
the port equals this limit or the limit of the authentication mode (802.1X for example) 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 MAC addresses on a port is independent of the MAC learning
limit described in MAC address table configuration in the Layer 2—LAN Switching Configuration Guide.
