Usage Information

The port-security feature is disabled by default on physical or port channel interfaces. In order to enable the port-security feature (for example, on port channel 1), run the following commands: 

OS10#config terminal

OS10(config)#interface port-channel 1

OS10(config-if)#switchport port-security

OS10(config-if-port-sec)#no disable.

The no disable command enables the port-security feature and operates either with default or user-configured values. Following are the default values:

  • MAC learn-limit is 1.
  • The sticky feature is disabled.
  • MAC movement is disabled.

The default values are set only if the corresponding values are not configured. If you configure or provide these values before enabling port-security, all the user-configured values are retained even after enabling port-security.

The port-security feature functionality becomes active on a port only if the feature is enabled globally and on that particular port. Disabling this feature either at global level or per port renders this feature inactive on that port.

The following table describes the relationship between switch and port level port-security configuration:

NOTE: When port-security becomes active on a port, all the MACs learned on that port are flushed if the mac-learning limit is not set to no-limit.
Example 
OS10(config-if-port-sec)# no disable

OS10(config-if-port-sec)# disable
