The Data layer handles functions related to data traffic encapsulation and traffic forwarding. The data layer allows access using one of four data ports from the underlying host. Each port connects to a dedicated internal virtual switch that can connect to external network devices.
The following image provides an example of a flow between a wireless access point and a Tunnel Concentrator HA deployment that is managed by ExtremeCloud IQ. In this example, the two Tunnel Concentrators share a VRRP address that is configured from ExtremeCloud IQ for the Tunnel Concentrator service. Traffic fom the access point reaches the shared VRRP address and is redirected to the active Tunnel Concentrator in the HA pair. The traffic flows through the data ports into the Tunnel Concentrator data layer.
Note
The VRRP configuration that provides redundancy for an HA deployment is configured in ExtremeCloud IQ, and is different than the VRRP configuration on a data port that provides access to the management interface.
