Fabric Attach
Fabric Attach (FA) complements and extends the Fabric Connect architecture to bring the Fabric services
directly to the end-users in the wired and wireless access as well as to the business applications located in
the data center.
Note
Fabric Attach is the Extreme naming of IEEE 802.1Qcj Auto Attach standard.
Figure 34 Fabric Attach Ecosystem
LLDP is the mechanism by which end-stations and networking devices communicate and discover from
each other about their neighbors and capabilities and Fabric Attach extends LLDP by adding new Fabric
Attach TLVs.
Figure 35 Fabric Attach Model
The Fabric Attach model defines four possible roles, as depicted in Figure 35.
• FA Server: This node is by definition an SPB BEB node that is part of Fabric Connect and is the
node in charge of requesting and signalling any Fabric Attach L2 VSN I-SID requests via SPB’s IS-IS
protocol.
