Programming LAN Bypass

The bypass function is used to link two independent

Ethernet ports when the system crash or powers off.

This means if your system is equipped with a LAN Bypass

function, a condition in your system will not interrupt your

network traffic. There are typically two communication

states for the bypass function, one is “Normal” state and

another is “Bypass” state. Lanner provides three methods

for enabling the LAN Bypass function:

When the system powers off, it can be forced to enable 1.

the LAN Bypass function through the BIOS settings.(

See BIOS Settings)

User can enable or disable the LAN Bypass function 2.

which is Controlled by GPIO by programming .

A watchdog timer can be used to control the LAN 3.

Bypass function by programming.

Please refer to the LAN_Bypass_Watchdog folder on the

Driver and Manual CD.

To compiler:

gcc wdbp.c -o wdbp

then switch to a root account to run ./LLCM2 for

excution:

./wdbp

For sample LAN bypass code, please see the LAN_Bypass

folder on the Driver and Manual CD.
