Chapter 46 Configuring Port Security
Port Security Configuration Distribution
This section includes the following topics:
• Enabling Distribution, page 46-18
• Locking the Fabric, page 46-18
• Committing the Changes, page 46-19
• Activation and Auto-learning Configuration Distribution, page 46-19
Enabling Distribution
All the configurations performed in distributed mode are stored in a pending (temporary) database. If
you modify the configuration, you need to commit or discard the pending database changes to the
configurations. The fabric remains locked during this period. Changes to the pending database are not
reflected in the configurations until you commit the changes.
Note Port activation or deactivation and auto-learning enable or disable do not take effect until after a CFS
commit if CFS distribution is enabled. Always follow any one of these operations with a CFS commit to
ensure proper configuration. See the “Activation and Auto-learning Configuration Distribution” section
on page 46-19.
Tip In this case, we recommend that you perform a commit at the end of each operation: after you activate
port security and after you enable auto learning.
To enable distribution using Fabric Manager, follow these steps:
Step 1 Expand a VSAN and select Port Security in the Logical Domains pane.
You see the port security configuration for that VSAN in the Information pane (see Figure 46-8).
Step 2 Click the Control tab.
You see the switches for that VSAN.
Step 3 In the Command column, select enable or disable from the drop-down menu.
Step 4 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.
