Configuring Database Synchronization
In a redundant master switch scenario, you can configure a redundant pair to synchronize their WMS and local
user databases. You can synchronize the databases manually or automatically.
When manually synchronizing the database, the active VRRP master synchronizes its database with the
standby. The command takes effect immediately.
When configuring automatic synchronization, you set how often the two switches synchronize their databases.
To ensure successful synchronization of database events, you should set periodic synchronization to a
minimum period of 20 minutes.
In the WebUI
1. On each switch, navigate to the Configuration > Advanced Services > Redundancy page.
2. Under Database Synchronization Parameters, do the following:
a. Select the Enable periodic database synchronization check box. This enables database
synchronization.
b. Enter the frequency of synchronizing the databases. A minimum value of 20 minutes is recommended.
3. Click Apply.
In the CLI
Use the following commands to configure database synchronization.
Command Description

To view the database synchronization settings on the switch, use the following command:
(host)#show database synchronize
Enabling Incremental Configuration Synchronization (CLIOnly)
When the master and local are synchronized, the complete configuration is typically sent to the local. However,
you now have the option to send only the incremental updates to the local using the following CLI commands:
