Configure Database Availability Group Network Properties

  • Article

 

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

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 or not the DAG network is enabled for replication.

What Do You Want to Do?

  • Use the EMC to configure database availability group network properties

  • Use the Shell to configure database availability group network properties

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the" database availability group" entry in the High Availability Permissions topic.

  1. In the console tree, navigate to Organization Configuration > Mailbox.

  2. In the result pane, on the Database Availability Group tab, select the DAG you want.

  3. In the work pane, on the Networks tab, right-click the DAG network you want, and then click Properties.

  4. Use the General tab to configure DAG network properties.

    • The top field contains the name of the DAG network. Each DAG network name must be unique and can't contain more than 128 characters.

    • Description of this network   Use this box to provide an optional description of up to 256 characters for the DAG network.

    • Edit subnets for this network Each DAG network must contain at least one subnet. Subnets using should be added using a format of IPAddress/Bitmask (for example, 192.168.1.0/24 for IPv4 subnets; 2001:DB8:0:C000::/54 for IPv6 subnets).

    • Enable replication   Leave this check box checked to enable replication traffic on the DAG network. When a DAG network is enabled for replication, MAPI traffic is restricted on that network. Clear this check box to prevent the DAG network from being used for replication (provided one or more replication networks are available) and to enable MAPI traffic on that network.

You need to be assigned permissions before you can perform this procedure. To see what permissions you need, see the" database availability group" entry in the High Availability Permissions topic.

In this example, a DAG network in a DAG named DAG1 is being renamed from its default network of DAGNetwork01 to a new name of CRNET1.

Set-DatabaseAvailabilityGroupNetwork -Name DAGNET1 -Identity DAG1\DAGNetwork01

In this example, a subnet of 10.0.0.0 and subnet mask of 255.0.0.0 is being added to a DAG network named DAGNET1 in a DAG named DAG1.

Set-DatabaseAvailabilityGroupNetwork -Subnets 10.0.0.0/8 -Identity DAG1\DAGNET1
