4.1.1 Ethernet Virtual Circuit
An Ethernet Virtual Circuit (EVC) represents a Carrier Ethernet service and is an entity that provides an
end-to-end connection between two or more customer endpoints. The instance of a specific EVC service
on the physical interface of each network device through which the EVC passes is called an Ethernet
Flow Point (EFP).
The key attributes of the flow point (FP) are:
end-to-end connection between two or more customer endpoints. The instance of a specific EVC service
on the physical interface of each network device through which the EVC passes is called an Ethernet
Flow Point (EFP).
The key attributes of the flow point (FP) are:
• FP ID—Generated when the FP is created.
• EVC ID—Associated EVC that the EFP a is part of.
• Encapsulation string—Defines the classification criteria for an incoming packet.
• Forwarding operation—Defines the operation to be applied on frames that belong to the EFP.
• Ingress rewrite operation—Defines the rewrites to be performed on the frames that belong to
• EVC ID—Associated EVC that the EFP a is part of.
• Encapsulation string—Defines the classification criteria for an incoming packet.
• Forwarding operation—Defines the operation to be applied on frames that belong to the EFP.
• Ingress rewrite operation—Defines the rewrites to be performed on the frames that belong to
the EFP before proceeding with the forwarding operation.
• Egress rewrite operation—Defines the rewrites to be performed on the frames being
transmitted out of the EFP. For multipoint services, only symmetrical egress operations are
supported on the PTF_10GE_4, PT_10GE_4, and PTSA_GE cards. For point-to-point
supported on the PTF_10GE_4, PT_10GE_4, and PTSA_GE cards. For point-to-point
