Detailed Description
State information is returned for subnets and for network interfaces, as described in the following tables.
Valid states for Internet Protocol version 4 (IPv4) subnets
| State | Description |
|---|---|
|
Up |
All defined network interfaces in the DAG are functional and available for communication. This is the expected and normal operational state. |
|
Down |
All defined network interfaces in the DAG are nonfunctional and have lost communication with each other and all external hosts. All connected network interfaces are in a Failed or Unreachable state. |
|
Partitioned |
One or more network interfaces in the DAG are in an Unreachable state, but at least two interfaces can communicate with each other or an external host. |
|
Misconfigured |
All subnets for a specified DAG network must have the same values for ReplicationEnabled and IgnoreNetwork. If any one of the subnets isn't configured with the same values for these parameters as all other subnets on the network, all subnets are in a Misconfigured state. |
|
Unavailable |
The network isn't enabled for replication or use by the DAG, or all DAG members attached to the network are inactive or unavailable. |
|
Unknown |
The system was unable to determine the state of the subnet. |
Valid states for network interfaces
| State | Description |
|---|---|
|
Up |
The network interface is functional and can communicate with all other network interfaces. This is the expected and normal operational state. |
|
Failed |
The network interface is unable to communicate with other network interfaces or external hosts, although other network interfaces on the local area network (LAN) are able to communicate with each other and external hosts. |
|
Unreachable |
The system was unable to communicate with at least one network interface whose state is Up. |
|
Unavailable |
The network interface isn't enabled for replication or use by the DAG, or the DAG member associated with this network interface is inactive or unavailable. |
|
Unknown |
The system was unable to determine the state of the network interface. |
You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Database availability groups" entry in the High Availability and Site Resilience Permissions topic.
Parameters
| Parameter | Required | Type | Description |
|---|---|---|---|
|
DomainController |
Optional |
Microsoft.Exchange.Data.Fqdn |
The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that retrieves data from Active Directory. |
|
Identity |
Optional |
Microsoft.Exchange.Configuration.Tasks.DatabaseAvailabilityGroupNetworkIdParameter |
The Identity parameter specifies the name of a DAG or a DAG network. |
|
Server |
Optional |
Microsoft.Exchange.Configuration.Tasks.ServerIdParameter |
The Server parameter specifies health information for the DAG network from a specific Mailbox server in the DAG. |
