Rules for Provisioning EVCs, EVC Maps, and Policers

To ensure valid provisioning, the rules below are enforced for EVCs, EVC maps, and policers.
In most cases the value of the status attribute for an entity provides a brief description of the
condition.
1. An EVC, EVC map, or policer is applied only if the respective status is running, which
2. Two EVC maps are considered to be duplicate if they both have the same values for the
3. Two EVCs are considered to be duplicate if they both have the same values for the
4. Two Policers are considered to be duplicate if they both have the same values for the
5. No EVC maps can have the same name.
6. No two EVCs can have the same name.
7. No two policers can have the same name.
8. If the network element is managed through a VLAN on a designated EFM bonding
9. If the CE‐VLAN‐ID preservation attribute of an EVC is disabled, all of the associated
10. When multiple EVC maps are applied to a common EVC, each EVC map must have the

12. No one Ethernet frame can be governed by more than one policer.

port, the following applies.
• Any EVC connected to the same MEN port with an s‐tag VID value equal to the
management VID value is invalid.
• If no EVCs are connected to the port, any EVC map sharing the same port but
connected to it as a UNI is made invalid if the EVC map is matching on a CE‐VLAN‐
ID equal to the VID of the system management EVC.
If a port is connected to the system management EVC as a UNI, it cannot be used by any
EVCs or EVC maps.
EVC maps must have the same value of the CE‐VLAN‐ID attribute.
