Port MAC security violation

A security violation occurs when the maximum limit for the number of secure MAC addresses allowed on the interface is exceeded.

When a security violation occurs, by default, the port shuts down.

Note

Note

Refer to Switch responses to security violations.

When the port shuts down after security violation, an administrator can explicitly bring up the interface or a shutdown timer can be configured. After the configured shutdown time, the interface automatically comes up and the port security configuration remains configured on the port.

Note

Note

When the device reboots after port shutdown due to security violation, the ports come up in the shutdown state.
