Missing Peer

When a collected device connects to a synthetic device through a subinterface functioning as the gateway, any outgoing traffic from a subinterface with a common parent, which isn't linked to a synthetic device, is ignored. The same behaviour happens when the gateway and uplink are an SVI and a trunk respectively, and there are VLANs allowed on the trunk that are not allowed on any linked synthetic devices.

The Missing Peer acts as a synthetic device designed to model such ignored traffic.

Unlike other synthetic devices, users can't configure missing peers; they are created and set up automatically by the Forward platform.

The device card provides a detailed list of the Missing Peer interfaces.

Any Missing Peer device within a Snapshot won't appear in the Source page like typical synthetic devices. Instead, it will be found on the Inventory page.
