Interfaces in the VMware Netflow context can be broadly classified into two types: Physical and SD-WAN.
- Physical – These are Ethernet (e.g. GE1, GE2), VLAN (e.g. br-network1), or IP interfaces (e.g. PPPoE or some USB modem interfaces).
- SD-WAN – These are point-to-point interfaces between a pair of VMware devices. On the overlay, there may be several tunnels between a pair of VMware devices. These tunnels use a proprietary protocol called VCMP that provides several features including encryption, retransmission, and more. The tunnels between two devices may be always present or may be created on-demand depending on the configuration. The end points of these tunnels are called “links” in VMware terminology. Typically, there is a "link" for each physical WAN-facing interface on an Edge.
- Replicated on both the tunnels.
- Load-balanced between the two tunnels.
- Sent on only one tunnel.
Template ID: 272
The interface option template is sent every 5 minutes by default. The timer is configurable.
