largest-anon-port Parameter

Description

This parameter controls the largest port number TCP can select as an ephemeral port. An application can use an ephemeral port when it creates a connection with a specified protocol but not a port number. Ephemeral ports are not associated with a specific application. When the connection is closed, the port number can be reused by a different application.
