the advantage of Fabric Attach is that you don't have to configure your VLANS on the uplinks AND that if there is no I-SID, no VLAN will be active on the uplink, thus making your broadcast domain smaller.
Now lets get Extreme Control (NAC) into place here. With policy you can assign a VLAN and I-SID (NSI) to a port based on X an Y condition.
Also very good!
But when the client disconnects, the I-SID to VLAN mapping remains on the switch!
=> You might ask: what's the point of having Fabric Attach?
I am probably missing some configuration piece (some timer ?) where the I-SID to VLAN mapping will disappear and the VLAN is no longer available on the switch. (test setup is with just 1 client on the switch).
Anyone idea's on this?
