Encapsulation
Encapsulation defines the matching criteria that maps a VLAN, a range of VLANs, class of service (CoS)
bits, Ethertype, or a combination of these to a service instance. You configure encapsulation in service instance
configuration mode. You must configure one encapsulation command per EFP (service instance).
Use the encapsulation service-instance configuration mode command to set encapsulation criteria. Different
types of encapsulations are default, dot1q, dot1ad, priority-tagged and untagged. Supported Ethertypes include
ipv4, ipv6, pppoe-all, pppoe-discovery, and pppoe-session.
Encapsulation classification options also include:
•
outer tag VLAN
•
outer tag CoS
•
inner tag VLAN
•
inner tag CoS
•
payload ethertype
After you have entered an encapsulation method, these keyword options are available in service instance
configuration mode:
• bridge-domain—Configures a bridge domain
• rewrite—Configures Ethernet rewrite criteria
