For each Always On availability group, returns either zero rows indicating that no network name is associated with the availability group, or returns a row for each availability-group listener configuration in the Windows Server Failover Clustering (WSFC) cluster. This view displays the real-time configuration gathered from cluster.

This catalog view does not describe details of an IP configuration, that was defined in the WSFC cluster.

Column nameData typeDescription
group_iduniqueidentifierAvailability group ID (group_id) from sys.availability_groups.
listener_idnvarchar(36)GUID from the cluster resource ID.
dns_namenvarchar(63)Configured network name (hostname) of the availability group listener.
portintThe TCP port number configured for the availability group listener.

NULL = Listener was configured outside SQL Server and its port number has not been added to the availability group. To add the port, pleaseuse the MODIFY LISTENER option of the ALTER AVAILABILITY GROUPTransact-SQL statement.
is_conformantbitWhether this IP configuration is conformant, one of:

1 = Listener is conformant. Only “OR” relations exist among its Internet Protocol (IP) addresses. Conformant encompasses every an IP configuration that was created by the CREATE AVAILABILITY GROUPTransact-SQL statement. In addition, if an IP configuration that was created outside of SQL Server, for example by using the WSFC Failover Cluster Manager, but can be modified by the ALTER AVAILABILITY GROUP tsql statement, the IP configuration qualifies as conformant.

0 = Listener is nonconformant. Typically, this indicates an IP address that could not be configured by using SQL Server commands and, instead, was defined directly in the WSFC cluster.
ip_configuration_string_from_clusternvarchar(max)Cluster IP configuration strings, if any, for this listener. NULL = Listener has no virtual IP addresses. For example:

IPv4 address:

IPv6 address: 2001::4898:23:1002:20f:1fff:feff:b3a3
