Classification Overview (CLI)
PTP 850 supports a hierarchical classification mechanism. The classification mechanism examines incoming frames
and determines their CoS and Color. The benefit of hierarchical classification is that it provides the ability to “zoom
in” or “zoom out”, enabling classification at higher or lower levels of the hierarchy. The nature of each traffic
stream defines which level of the hierarchical classifier to apply, or whether to use several levels of the
classification hierarchy in parallel.
The hierarchical classifier consists of the following levels:
•
Logical interface-level classification
• Service point-level classification
•
Service level classification
Configuring Ingress Path Classification on a Logical Interface
(CLI)
Logical interface-level classification enables you to configure classification on a single interface or on a number of
interfaces grouped tougher, such as a LAG group.
The classifier at the logical interface level supports the following classification methods, listed from highest to
lowest priority. A higher level classification method supersedes a lower level classification method:
•
VLAN ID
• 802.1p bits.
•
DSCP values.
• MPLS EXP field.
•
Default CoS
