Command History
Usage Guidelines To use this command, DPVM must be enabled using the dpvm enable command.
When autolearn is enabled, the system automatically creates the DPVM database by learning about
devices currently logged or newly logged devices with a VSAN. This is a quick way to create the DPVM
database, which can later be edited. Autolearn features include the following:
• An autolearned entry is created by adding the device PWWN and VSAN to the active DPVM
database.
• The active DPVM database must be present when autolearning is enabled.
• Autolearned entries can be deleted from the active DPVM database by the user until autolearning is
disabled. Autolearned entries are not permanent in the active DPVM database until autolearning is
disabled.
• If a device logs out when autolearning is enabled, the device entry is deleted from the active DPVM
database.
• If a particular device logs into the switch multiple times through different ports, then only the VSAN
corresponding to last login is associated with the device.
• Autolearn entries do not override previously configured activate entries.
Examples The following example shows how to enable autolearning for the DPVM database.
switch# config terminal
switch(config)# dpvm auto-learn
