You see the switches for that VSAN. Click the Command column and select enable or disable from the drop-down menu. Click the Apply Changes icon to save the changes. Locking The Fabric The first action that modifies the existing configuration creates the pending database and locks the feature in the VSAN. Once you lock the fabric, the following situations apply: • No other user can make any configuration changes to this feature. • A copy of the configuration database becomes the pending database. Committing the Changes If you commit the changes made to the configurations, the configurations in the pending database are distributed to other switches. On a successful commit, the configuration change is applied throughout the fabric and the lock is released. Activation and Auto-learning Configuration Distribution Activation and auto-learning configurations in distributed mode are remembered merely as actions to be performed when you commit the changes in the pending database. Learned entries are temporary and do not have any role in determining if a login is authorized or not. As such, learned entries do not participate in distribution. When you disable learning and commit the changes in the pending database, the learned entries become static entries in the active database and are distributed to all switches in the fabric. After the commit, the active database on all switches are identical and learning can be disabled. If the pending database contains more than one activation and auto-learning configuration when you commit the changes, then the activation and auto-learning changes are consolidated and the behavior may change (see Table 46-3). 46-20 Cisco MDS 9000 Family CLI Configuration Guide OL-16184-01, Cisco MDS SAN-OS Release 3.x
