Each database availability group (DAG) network has several properties that you can configure, including the name of the DAG network, a description field for the DAG network, a list of subnets that are used by the DAG network, and whether the DAG network is enabled for replication.

What do you want to do?

Use the EAC to configure database availability group network properties

  1. In the EAC, go to Servers > Database Availability Groups.

  2. Select the DAG you want to configure, and in the Details pane, under the DAG network you want to configure, choose:

    • Disable Replication or Enable Replication   Configures the replication settings for the DAG network.

    • Remove   Removes a DAG network. Before you can remove a DAG network, you must first remove all associated subnets from the DAG network.

    • View details   Configures DAG network properties, such as the name, description, and associated subnets for the DAG network. You can also view the network interfaces associated with those subnets, and enable or disable replication for the DAG network.

Use the Shell to configure database availability group network properties

This example adds a subnet of and subnet mask of to the DAG network MapiDagNetwork in the DAG DAG1.

Copy Code
Set-DatabaseAvailabilityGroupNetwork -Subnets -Identity DAG1\MapiDagNetwork

How do you know this worked?

To verify that you've successfully configured the DAG network, do the following:

  • In the Shell, run the following command to display DAG network configuration settings and verify the DAG network was configured successfully.

    Copy Code
    Get-DatabaseAvailabilityGroupNetwork <DAGNetworkName> | Format-List
