Config Type: 0 = Automatic Occupancy Limit: This attribute indicates the maximum amount of time, in Time Units (TUs), that a point coordinator MAY control the usage of the wireless medium without relinquishing control for long enough to allow at least one instance of Distributed Coordination Function (DCF) access to the medium. The default value of this attribute SHOULD be 100, and the maximum value SHOULD be 1000. CFP Period: The attribute describes the number of DTIM intervals between the start of Contention-Free Periods (CFPs). CFP Maximum Duration: The attribute describes the maximum duration of the CFP in TU that MAY be generated by the Point Coordination Function (PCF). BSSID: The WLAN Radio's base MAC address. For WTPs that support more than a single WLAN, the value of the WLAN Identifier is added to the last octet of the BSSID. Therefore, a WTP that supports 16 WLANs MUST have 16 MAC addresses reserved for it, and the last nibble is used to represent the WLAN ID. Beacon Period: This attribute specifies the number of TUs that a station uses for scheduling Beacon transmissions. This value is transmitted in Beacon and Probe Response frames. Country Code: This attribute identifies the country in which the station is operating. The first two octets of this string is the two-character country code as described in document ISO/IEC 3166- 1. The third octet MUST be one of the following: 1. an ASCII space character, if the regulations under which the station is operating encompass all environments in the country, 2. an ASCII 'O' character, if the regulations under which the station is operating are for an outdoor environment only, or /* DTIM Period: This attribute specifies the number of Beacon intervals that elapses between transmission of Beacons frames containing a TIM element whose DTIM Count field is 0. This value is transmitted in the DTIM Period field of Beacon frames. */ 83.

AC Name with Index Same as AC Name with Priority, defined in CAPWAP RFC 5415. The AC Name with Priority message element is sent by the AC to the WTP to configure preferred ACs. The number of instances of this message element is equal to the number of ACs configured on the WTP. The WTP also uses this message element to send its configuration to the AC. 0 1 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | Index | AC Name... +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ Type: 91 for AC Name with Index Length: >= 2 Priority: A value between 1 and 255 specifying the priority order of the preferred AC.

Cisco SPAM AP LED Flash Config LWAPP ===== In this section Cisco vendor specific message elements used in LWAPP are listed. Some of these elements are used by Cisco in CAPWAP where the vendor specific LWAPP message element is encapsulated in a vendor specific CAPWAP message element. So in CAPWAP we see headers like this: Vendor spec CAPWAP | Vedor spec LWAPP | Vendor specific LWAPP data 00 40 96 00 00 68 | 00 40 96 00 00 86 | ... 20.
