active-scan enable Sends probe any requests (probe requests with a null SSID
name) to solicit probe responses from other access points.
(Refer to Chapter 22, ” Rogue Detection and
Countermeasures”.)
beacon-interval 100 Waits 100 ms between beacons.
countermeasures Not configured Does not issue countermeasures against any device.
(Refer to Chapter 22, ” Rogue Detection and
Countermeasures”.)
dtim-interval 1 Sends the delivery traffic indication map (DTIM) after every
beacon.
frag-threshold 2346 Uses the short-retry-count for frames shorter than 2346
bytes and uses the long-retry-count for frames that are
2346 bytes or longer.
max-rx-lifetime 2000 Allows a received frame to stay in the buffer for up to
2000 ms (2 seconds).
max-tx-lifetime 2000 Allows a frame that is scheduled for transmission to stay in
the buffer for up to 2000 ms (2 seconds).
