Capwap Mailing List: RE: BSSID-WLAN mappings

[Bob O'Hara (boohara) (boohara]

Puneet,

 

The 1:1 mapping of WLAN to BSSID is all that is described in the 802.11 standard.  There is no method in that standard defined to support more than a single BSS on a BSSID.  Adding such a mechanism to CAPWAP would only serve to promote noninteroperable implementations of 802.11 on various WTPs.

Subject: [Capwap] BSSID-WLAN mappings

the BSSID description in Section 11.9.1 'WTP Radio Configuration' 
notes that a WTP that supports 16 WLANS MUST have 16 MAC addresses reserved for 
it. Why? ie. what part of the protocol does not work if we have multiple SSIDs 
on a single BSSID? (whether thats good design or bad is a different matter). 
Since the WLAN ID could be used in all such places to convey WLAN information 
back to the AC, why do we need to mandate this 1:1 BSSID-WLAN 
mapping?

Thanks,
Puneet
