### Availability group listener requirement

101+
When you run [sp_addpullsubscription_agent](../../../relational-databases/system-stored-procedures/sp-addpullsubscription-agent-transact-sql.md) for a subscriber that's part of an AG, you must pass the `@subscriber` parameter value to the stored procedure as the AG listener name. If you run [!INCLUDE [sssql16-md](../../../includes/sssql16-md.md)] and earlier versions, or [!INCLUDE [sssql17-md](../../../includes/sssql17-md.md)] before CU 16, the stored procedure doesn't reference the AG listener name. It creates the subscription with the subscriber server name on which the command is executed. To resolve this issue, manually update the `@subscriber` parameter on the [Replication Distribution Agent](../../../relational-databases/replication/agents/replication-distribution-agent.md) with the AG listener name value.
102+
103+
If the subscriber AG listener uses a non-default port, providing port number as part of the AG listener name in the `@subscriber` parameter isn't supported on Windows. As a workaround, you can create an alias for the listener and port on publisher, distributor, and subscriber server using [Aliases (SQL Server Configuration Manager)](../../../tools/configuration-manager/aliases-sql-server-configuration-manager.md) or the [SQL Server Client Network Utility tool (cliconfg)](/previous-versions/windows/desktop/odbc/dn170508(v=vs.85)) for [!INCLUDE [sssql22-md](../../../includes/sssql22-md.md)] and later versions, and pass the alias as the `@subscriber` parameter value.
