Setting up an eIRF system

Overview

eIRF integrates multiple lower-layer devices with a higher-layer IRF fabric to provide high-density, low-cost
connectivity at the access layer.
In an eIRF system, the higher-layer IRF fabric is called the parent fabric and the lower-layer devices are
called port extenders (PEXs). You can manage and configure the PEXs from the parent fabric as if they
were interface cards on the parent fabric.
Typically, eIRF works at the access layer of data centers. As shown in
network is virtualized into an eIRF system. The system contains one parent fabric (a two-chassis IRF fabric)
and multiple PEXs to provide connectivity for servers and hosts.
