Overview of Service Point Classification (CLI)
Service points connect the service to the network element interfaces. It is crucial that the network element have a
means to classify incoming frames to the proper service point. This classification process is implemented by means
of a parsing encapsulation rule for the interface associated with the service point. This rule is called the Interface
Type, and is based on a key consisting of:
• The Interface ID of the interface through which the frame entered.
• The frame’s C-VLAN and/or S-VLAN tags.
The Interface Type provides a definitive mapping of each arriving frame to a specific service point in a specific
service. Since more than one service point may be associated with a single interface, frames are assigned to the
earliest defined service point in case of conflict.
