Supported EVC Features
Supported EVC Features
• 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
• EVC forwarding
• MAC address learning and aging
• EVCs on EtherChannels
• Hairpinning
• Split horizon
• Layer 2 protocol tunneling and QinQ
• EVC MAC address security
• Bridging between switchports and EFPs
• MSTP (MST on EVC bridge domain)
• EFP statistics (packets and bytes)
• QoS aware EVC/EFP per service instance
These Layer 2 port-based features can run with EVC configured on the port:
• PAGP
• LACP
• UDLD
• LLDP
• CDP
• MSTP
