Service instance—you create, delete, and modify EFP service instances on Ethernet interfaces.
Encapsulation—you can map traffic to EFPs based on:
802.1Q VLANs (a single VLAN or a list or range of VLANs)
–
802.1Q tunneling (QinQ) VLANs (a single outer VLAN and a list or range of inner VLANs)
–
– Double-tagged frames mapped to EVC based on C-tags (wildcard S-Tags)
– Cisco QinQ ethertype for S-tags
Bridge domains—you can configure EFPs as members of a bridge domain (up to 64 EFPs per bridge
domain).
Rewrite (VLAN translation)
– Pop symmetric only—the supported rewrite configuration implies egress pushing (adding a tag)
pop 1 removes the outermost tag
pop 2 removes the two outermost tags
pop symmetric adds a tag (or 2 tags for pop 2 symmetric) on egress for a push operation
QinQ with rewrite

Ingress rewrite is not supported
