For details, see Configuring an SSID Profile in the Configuration-User Access and Authentication Configuration Guide . 11ac outdoor access point (AP), is designed explicitly for high density public venues such as airports, conventions centers, plazas & malls, and other dense urban environments. EAP-TLS D. The AP Likewise, setting the DTIM (Delivery Traffic Indicator Message) period on the AP to a higher value will reduce how often clients are woken up to receive pending multicast/unicast packets but this will reduce throughput and, more importantly, since multicast packets are buffered, a large DTIM can cause a buffer overflow. A DTIM period field of 5 indicates every fifth beacon is a DTIM. 2 DTIM is set to a deafult value of 1 on a per radio basis (ie once for each band in a dual band FortiAP). A DTIM interval determines when the APs must deliver broadcast and multicast frames to their associated clients in power save mode. The support article suggests a DTIM of 5 and changing Directed MC/BC to 0 for less congested environements or where device battery life is of more concern (these changes assume a standard beacon interval for the SSID of 100ms- so that a DTIM of 5 results in a DTIM broadcast every 500ms/ 0. In this case, the medium is a channel for example <1, 6 or 11>. 802 11 Beacon Frame 802 11 Beacon Frame Published on : by Management Frames - 802.
