About Auto-Learn
You can instruct the switch to automatically learn (auto-learn) the port security configurations over a
specified period. The auto-learn option allows any switch in the Cisco MDS 9000 Family to
automatically learn about devices and switches that connect to it. Use this feature to activate port security
feature for the first time as it saves tedious manual configuration for each port. Auto-learn is configured
on a per-VSAN basis. If enabled, devices and switches that are allowed to connect to the switch are
automatically learned, even if you have not configured any port access. Learned entries on a port are
cleaned up after a shutdown command is issued on that port.
Activating Port Security
By default, the port security feature is not activated.
When you activate the port security feature, the auto-learn option is also automatically enabled. You
can choose to activate the port-security feature and disable auto-learn. In this case, you need to manually
populate the port security database by individually securing each port.
