Figure 37 Fabric Attach LLDP Service Signalling TLV
Note
A FA Standalone Proxy node will only process FA signalling TLVs where the I-SID value is
null
There are a number of possible ways in which a Fabric Attach I-SID binding can be assigned:
• FA Client expressly asks for one, or more, VLAN:I-SID bindings. The FA Proxy or FA Server will then
handle the assignment request. This is typically the case with ExtremeWireless FA Client Access
Points where the ExtremeCloud Appliance WLAN controller programs the FA mode configuration in
the AP triggering FA assignment requests for the required VLAN:I-SID bindings.
Figure 38 FA Client Requests VLAN:I-SID Binding
• FA Proxy or FA Server, configured with Zero Touch FA Auto Client Attach, detects that an FA Client
of type X has been connected to an access port. If a Zero-Touch-Client policy exists for the FA
Client type, this will determine the VLAN:I-SID binding to which the device will be attached. If the FA
Client was connected to an FA Proxy, this will request the service binding from the FA Server; if
instead the FA Client is directly connected to the FA Server, the FA Server can automatically
provision the VSN on the corresponding port. This is a typical approach for onboarding video
surveillance IP cameras.
