Supported EVC Features

This section contains the following supported EVC features:

•Service instance—create, delete, and modify EFP service instances on Ethernet interfaces.

•Encapsulation—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—configure EFPs as members of a bridge domain (up to 64 EFPs per bridge domain).

•DHCP client—retrieves the host information from the DHCP server.

•Rewrite (VLAN translation)

–Pop symmetric only—the supported rewrite configuration implies egress pushing (adding a tag)

1.pop 1 removes the outermost tag

2.pop symmetric adds a tag on egress for a push operation

–QinQ with rewrite

–Ingress rewrite is not supported

•EVC forwarding

•MAC address learning and aging

•EVCs on EtherChannels

•Split horizon

•EVC MAC address security

•MSTP (MST on EVC bridge domain)

•EFP statistics (packets and bytes)

•QoS aware EVC/EFP per service instance

•Pop 2 configuration supports layer 2 and layer 3 operations. Additionally, it supports GigabitEthernet and port channel interfaces.
