cevcSIType 1.3.6.1.4.1.9.9.613.1.4.1.1.11

This object specifies the type of the service instance. It mentions if the service instance is either a regular or trunk or l2context service instance. 'regular' If a service instance is configured without any type specified, then it is a regular service instance. 'trunk' If the service instance is configured with trunk type, then it is a trunk service instance. For a trunk service instance, its Bridge domain IDs are derived from encapsulation VLAN plus an optional offset (refer cevcSIForwardBdNumberBase object). 'l2context' If the service instance is configured with dynamic type, then it is a L2 context service instance. The Ethernet L2 Context is a statically configured service instance which contains the Ethernet Initiator for attracting the first sign of life. In other words, Ethernet L2 Context service instance is used for catching the first sign of life of Ethernet frames to create dynamic Ethernet sessions service instances.
