Total Access 5000 Business Services Deployment Guide
Figure F‐4 provides a more detailed view of the mapping of the customer VLANs into the
EVC in the UNI‐to‐MEN direction. For this example, the CoS for each received customer
frame is inherited from the P‐bit value of the outermost customer VLAN tag. The following
provisioning would apply on each system.
• EVC #1: MEN Port = EFM‐Group 1/0/1, S‐tag = 101, 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 = 1, MEN‐Pri = Inherit
UNI

Example #3: EVC Map Forwarding

When two or more EVC maps have overlapping criteria and an incoming packet matches two
or more of the criteria for the EVC maps, the EVC map that has provisioning options higher in
the order of precedence (refer to Rule 13 on page F‐3) is used to forward traffic.
An example in which three EVC maps are configured on the NCTE is defined as follows:
F-12
CE VLAN 1
UNI
CE VLAN 2
