Fabric Attach Solution Overview
Fabric Attach (FA) is a feature that provides the service provisioning benefits of Fabric Connect to
networking stub attached devices that do not support SPBM and where it makes little sense to IS-IS
computing shortest paths. These devices can include WLAN Access Points, wiring closet access switches,
servers, virtual machines, IP cameras, and Internet of Things (IoT). Devices supporting FA can dynamically
request the network to create and provision VLAN and SPB virtual service mappings from the access layer
of the network. By including Extreme Identity Engines policy engine in an FA solution, access layer
provisioning can be fully automated by leveraging authentication of end users and devices, and then
signaling to the access switch the VLAN and SPB service to create and assign to the user/device.
In summary, FA provides the ability to attach users and applications directly to the correct SPB virtual
service (I-SID) by automatically adding the necessary VLANs on the FA components and tying those VLANs
with the appropriate I-SID on the SPBM (FC) boundary nodes (BEBs enabled with FA Server).
