Each I-SID/VLAN association that is configured on an ISW FA Client creates a Customer VLAN (C-VLAN) User-Network Interface (UNI), when the assignment becomes active following acceptance by an FA Server.
Note
FA Proxy/Client devices support only C-VLAN UNIs. They do not support switched UNIs.
If an I-SID-to-VLAN assignment is accepted by the FA Server, the assignment state is updated to active. If an I-SID-to-VLAN assignment is not accepted by the FA Server, the assignment state is updated to rejected.
Assignment accepted (2)
Rejection: generic (3)
Rejection: Fabric Attach resources unavailable (4)
Rejection: VLAN invalid (6)
Rejection: VLAN resources unavailable (8)
Rejection: application interaction issue (9)
Note
Data exchanges (I-SID/VLAN assignments) between an FA Proxy and an FA Server/FA Client are supported, as are exchanges between an FA Server and an FA Proxy/FA Client. FA Proxy to FA Proxy and FA Server to FA Server interactions are not supported.
If the FA Proxy or FA Client has access to an FA Server, these assignments are advertised for possible use by the FA Server, using FA signaling.
All I-SID/VLAN assignments defined on an FA Proxy, as well as those received from FA Clients when client proxy operation is enabled, start in the ‘pending‘ state. The I-SID/VLAN assignment state is updated based on feedback received from the FA Server. If an assignment is accepted by the FA Server, its state is updated to ‘active‘. A server can also reject proposed I-SID/VLAN assignments. In this case, the assignment state is updated to ‘rejected‘. Data describing the reason for the rejection may also be available.
