Network Application Platforms
There are two ways to enable the bypass on the system:
The LAN bypass can be turned on or off in two system 1.
states, i.e., power on and power off. The following
are the illustration of the possibilities of LAN bypass
configuration with respect to both power-on and
power-off states.

A watchdog timer can be used to control the LAN 2.
Bypass function dynamically by programming. Lanner
also provides sample code for bypass control with
WDT via programming. For sample code, look in the
LAN_Bypass_Watchdog directory under Driver and
Manual CD.
To compile:
#gcc wdbp.c -o wdbp
then switch to a root account to run ./wdbp for
excution:
#./wdbp
Commands:
Enable the bypass
#wdbp.exe –f
Set Watchdog Timer. This command will set the time
interval at which the counter will start count down.
#wdbp.exe -wl xxx (xxx: 1-255 sec for timer count
down)
Reset Watchdog Timer. This command will reset the
watchdog timer’s counter and the bypass status to
non-bypass.
#wdbp.exe -wr xxx (xxx: 1-255 sec for timer count
down)
