Data Fields Security B Security DTIM Interval RTS Threshold The interval for sending the Delivery Traffic Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and multicast messages. When the WRP400 has buffered broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast messages. Enter a value between 1 and 255. Default: 1 The WRP400 sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. If you encounter inconsistent data flow, only minor reduction of the default value, 2347, is recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/ CTS mechanism will not be enabled. Default: 2347 The Security module includes the following pages: • "Security > Firewall" on page 136 • "Security > VPN Passthrough" on page 137 Cisco Small Business WRP400 Administration Guide 135
