Use the Protocols tab to configure connection attributes for various communication protocols used by WebLogic Server, including:

Note that all configuration attributes on this page apply to connections that use the server's default Listen Port and Listen Address settings. You can optionally configure additional addresses and ports using network channels and network access points; the protocol support for these connections can be configured independently of the attributes on this page.

Attribute Label	Description	Value Constraints
Default Protocol	The protocol to be used for connections when none is specified. MBean: weblogic.management. configuration.ServerMBean Attribute: DefaultProtocol	Default: "t3" Valid values: "t3" "t3s" "http" "https" "iiop" Configurable: yes Readable: yes Writable: yes
