Create an EVC Map

This subsection details the following information:
• Definition of a map
• Steps for creating a map
• Steps for configuring a map
• Map example

Map Definition

Define the association of customer traffic on a UNI port with an EVC by defining an entity
called a EVC‐map. Each EVC‐map is typically associated with a single customer and specifies
parameters including the customer VLAN ID and Class of Service (CoS) behavior of the traffic
from the customer. Use a map to classify traffic for use by an EVC for forwarding and for use
by a policer for rate limiting.

Map Guidelines

To ensure valid provisioning, enforce the following guidelines when creating a map:
• A map is applied only if the EVC map's status is Running (as indicated in the show evc‐
• Two maps are considered to be duplicate if they both have the same values for the
• No two maps can have the same name
• If the system is managed through a VLAN on a designated Ethernet port, the
• If the CE‐VLAN‐ID preservation attribute of an EVC is disabled, all of the maps connected
• If two or more maps have either the same UNI or the same associated EVC, only one of

– Differentiated Services Code Point (DSCP) value
– Untagged priority tagged frames

the maps can be provisioned to allow untagged and priority tagged frames
