General Guidelines for Provisioning Ethernet Services
When provisioning Ethernet services, it is recommended to follow these
guidelines:
•
Use the same Service ID for all service fragments along the path of the service.
•
Do not re-use the same Service ID within the same region. A region is defined
as consisting of all IP-20 devices having Ethernet connectivity between them.
•
Use meaningful EVC IDs.
•
Give the same EVC ID (service name) to all service fragments along the path of
the service.
•
Do not reuse the same EVC ID within the same region.
It is recommended to follow these guidelines for creating service points:
•
Always use SNP service points on NNI ports and SAP service points on UNI
ports.
•
For each logical interface associated with a specific service, there should
never be more than a single service point.
•
The transport VLAN ID should be unique per service within a single region.
That is, no two services should use the same transport VLAN ID.
