Example #2: Two Ce-Vlans Mapped To One Evc; Figure F-1. E-Line Service - Evc Per Ce-Vlan; Figure F-2. Detailed Mapping Of Two Point-To-Point Evcs - ADTRAN Total Access 5000 Deployment Manual

Figure F‐2 provides a more detailed view of the mapping of the customer VLANs into the
EVCs in the UNI‐to‐MEN direction. For this example, both EVCs reside on the same bonding
group, and the CoS for each received customer frame is inherited from the P‐bit value of the
outermost customer VLAN tag. The following provisioning applies on each system.
• EVC #1: MEN Port = EFM‐Group 1/0/1, S‐tag = 101, CE‐VLAN‐ID Preservation = Enabled
• EVC #2: MEN Port = EFM‐Group 1/0/1, S‐tag = 102, CE‐VLAN‐ID Preservation = Enabled
• EVC Map #1: UNI = Ethernet 1/0/1, CE‐VLAN‐ID = 1, EVC = 1, MEN‐Pri = Inherit
• EVC Map #2: UNI = Ethernet 1/0/1, CE‐VLAN‐ID = 2, EVC = 2, MEN‐Pri = Inherit

Example #2: Two CE-VLANs Mapped to One EVC

Figure F‐3 illustrates an example of two customer VLANs that ingress the network element on
a common UNI port and map to a common EVC. Customer VLANs 1 and 2 are mapped to an
EVC with SVID 101.
