The Ethernet time out value ranges from 30 to 255 seconds. If the value is: - 0: the Ethernet Time Out function is disabled. - 1: detect Ethernet timeout by hardware circuitry. - 2: send WLAP Alive BPDU on Ethernet interface to let other WLAP on the same Ethernet segment to detect it's existence. - 3: keep track of WLAP Alive BPDU on Ethernet inter- face. If the BPDU is missing for 'WLAP Hello Time' seconds, both Ethernet Attached and Activity LEDs will flash and the RF interface is disabled until the WLAP Alive BPDU is received again, then the AP will reset itself. When the Ethernet connection is broken: - if WLAP Mode is disabled, the AP will clear the MU table and disable the RF interface until the Ethernet connection is up. - if WLAP Mode is enabled, the AP will set the timeout value to zero and reset itself. The default value is 0.
