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.
