Ethernet Flow Points
An Ethernet flow point (EFP) can represent a port that is configured for participation in a specific
VLAN.
If you right-click an EFP in Prime Network Vision and then choose Inventory, the inventory window is
displayed with the corresponding port selected in Physical Inventory.
EFPs that are located in a switching entity represent Ethernet ports that are configured as switch ports
(in either Access, Trunk, or Dot1Q tunnel mode).
Figure 12-21 shows an example of EFPs configured as switch ports in Prime Network Vision.
Figure 12-21 EFPs Configured as Switch Ports
EFPs that are located directly inside a VLAN represent one of the following:
• Termination point EFPs—Ethernet ports that are at the edge of a Layer 2 domain flow, such as a
VLAN, on which traffic enters a Layer 3 domain or a different Layer 2 domain, such as EoMPLS.
These ports are found on such devices as the Cisco 7600 series, Cis co GSR, a nd Ci sco ASR 900 0
series devices.
These EFPs are typically connected to a switching entity inside the VLAN by a VLAN link, as
shown in Figure 12-22.
