Enabling Autolearning

To enable autolearning, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# dpvm auto-learn
switch(config)# no dpvm auto-learn

Clearing Learned Entries

You can clear DPVM entries from the active database (if autolearn is still enabled) using one of two
methods.
•
•
Note These two commands do not start a session and can only be issued in the local switch.

Configuring DPVM Database Distribution

If the DPVM database is available on all switches in the fabric, devices can be moved anywhere and offer
the greatest flexibility. To enable database distribution to the neighboring switches, the database should
be consistently administered and distributed across all switches in the fabric. The Cisco SAN-OS
software uses the Cisco Fabric Services (CFS) infrastructure to achieve this requirement (see
"Using the CFS
Using the CFS infrastructure, each DPVM server learns the DPVM database from each of its neighboring
switches during the ISL bring-up process. If you change the database locally, the DPVM server notifies its
neighboring switches, and that database is updated by all switches in the Fabric.
If fabric distribution is enabled, all changes to the configuration database are stored in the pending
database. These changes include the following tasks:
•
•
•
These changes are distributed to all switches in a fabric when you commit the changes. You can also
discard (abort) the changes at this point.
You can view the contents of the pending database by issuing the show dpvm pending command.
Tip
OL-6973-03, Cisco MDS SAN-OS Release 2.x
To clear a single autolearn entry, use the clear dpvm auto-learn pwwn command.
switch# clear dpvm auto-learn pwwn 55:22:33:44:55:66:77:88
To clear all autolearn entries, use the clear dpvm auto-learn command.
switch# clear dpvm auto-learn
