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.
SAP Classification (CLI)
SAPs can be used with the following Interface Types:
•
All to one
–
All C-VLANs and untagged frames that enter the interface are
classified to the same service point.
•
Dot1q
–
A single C-VLAN is classified to the service point.
•
QinQ
–
A single S-VLAN and C-VLAN combination is classified to the service
point.
•
Bundle C-Tag
–
A set of multiple C-VLANs is classified to the service point.
•
Bundle S-Tag
–
A single S-VLAN and a set of multiple C-VLANs are classified to
the service point.
