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 from the following configuration options.


    These options will only be visible if you have selected Configure database availability group networks manually on the DAG properties page.

  • 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 Exchange Management 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.

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

    Get-DatabaseAvailabilityGroupNetwork <DAGNetworkName> | Format-List
