Forces the VSAN 1 port security database to activate despite conflicts.
Database Reactivation
To reactivate the port security database, follow these steps:
Procedure
Step 1
switch# configure terminal
switch(config)#
Enters configuration mode.
Step 2 switch(config)# no port-security auto-learn vsan 1
Disables auto-learning and stops the switch from learning about new devices accessing the switch. Enforces
the database contents based on the devices learned up to this point.
Step 3 switch(config)# exit
switch# port-security database copy vsan 1
Copies from the active to the configured database.
Step 4 switch# configure terminal
switch(config)# port-security activate vsan 1
Activates the port security database for the specified VSAN, and automatically enables auto-learning.
Example

without the force option until you disable auto-learning.
