By default, SQL Server uses static TCP port number 1433 for the MSSQLSERVER instance. 1434 is used for UDP connections.TCP port 1433 is the default port for communication between Microsoft SQL Server and its applications. SQL Server powers many of the world's top data-driven solutions, and port 1433 is widely used to connect to the database.By default, the typical ports used by SQL Server and associated database engine services are: TCP 1433, 4022, 135, 1434, UDP 1434. The table below explains these ports in greater detail.
What is port 5022 used for : The inbound port for AG replication is 5022 by default, so all replication traffic is sent TO port 5022. Accordingly, you see the network reads occurring on port 5022, as SQL Server is listening on port 5022 and reading packets that are sent to that port.
How do I find SQL ports
In SQL Server Configuration Manager, expand SQL Server Network Configuration and then select Protocols for <instance name> on the left panel. To identify the TCP/IP Port used by the SQL Server Instance, right click on TCP/IP and select Properties from the drop down as shown below.
What is the port 3389 used for : Port 3389 is used to facilitate remote access to Windows computers through the Remote Desktop Protocol (RDP). This connection method allows users to operate a remote desktop or server as if they were physically present, regardless of location.
Select the Port type of the rule. Specify the ports 1433 and 1434 to which this rule applies inside the Specific local ports area. In this case, 1433 stands for the SQL server, and 1434 for the SQL server browser. SQL Server uses UDP Port 1434 for communication with applications. If you are running an application that requires connectivity with the SQL Server, you must enable port 1434 for SQL Server to listen on.
What is port 3389
Port 3389 is used to facilitate remote access to Windows computers through the Remote Desktop Protocol (RDP). This connection method allows users to operate a remote desktop or server as if they were physically present, regardless of location.Always On Availability Group uses port 5022 as the default port number in order for the secondary replica to connect to the primary replica. In some organizations where ICMP responses are disabled, the PING test might return a request timed out message.AMQP assigned port number is 5672 or 5671 for AMQPS (TLS/SSL encrypted AMQP). AMQP stands for Advanced Message Queuing Protocol, and it is an open standard application layer protocol. Ports used by the database engine
Port 1433/TCP: Default instance running over TCP.
Port 1434/TCP: Dedicated admin connection.
Port 4022/TCP: SQL Server service broker.
Port 135/TCP: Used by the Transact-SQL debugger.
Port 1434/UDP: Used by the SQL browser service.
Port 80/TCP: HTTP connections through a URL.
What is port 1434 for SQL Server : UDP 1434 is used for Named SQL Server instances and SQL Browser service listens on this port for any incoming requests to a named sql server instance. The browser service will respond to the client with TCP port no. for the requested named instance.
What is port 22 and 3389 : Port 22 is used for Secure Shell data, the text-based console used primarily with Linux/Unix systems and network devices, Port 3389 is assigned for RDP (Remote Desktop Protocol), primarily used for accessing the console of Windows-based systems.
What is port 1433 used for
Port 1433 for TCP is needed to connect to the SQL database instance. By default, SQL will attempt to use 1433. If that port is unavailable, it will automatically choose another port. If this is the case, that port will need to be opened through the firewall instead. UDP 1434 is used for Named SQL Server instances and SQL Browser service listens on this port for any incoming requests to a named sql server instance.Specify the ports 1433 and 1434 to which this rule applies inside the Specific local ports area. In this case, 1433 stands for the SQL server, and 1434 for the SQL server browser. In this step, leave the default selection: Allow the connection.
What is port 1435 used for : The CICS® External Call Interface (ECI) has a registered port number, 1435. Well-known ports are used only to establish communication between client and server processes. After that, the server allocates an ephemeral port number for subsequent use.
