Hi,

If i am configuring below config under /etc/config/system file , The STATUS
LED working fine based on eth0 link up/down.

config led 'led_status'
        option name 'STATUS'
        option interval '50'
        option sysfs 'db120:green:status'
        option default '0'
        option trigger 'netdev'
        option mode 'link'
        option dev 'eth0'

The switch button defined as below under /etc/hotplug.d/button/50-wps

if [ "$ACTION" = "pressed" -a "$BUTTON" = "lanwifi" ]; then
        echo "255" >
/sys/devices/platform/leds-gpio/leds/db120:green:status/brightness
fi

This working fine. I need to add condition as below:

if [ "$ACTION" = "pressed" -a "$BUTTON" = "lanwifi" ]; then

NEED TO ADD CONDITION
(config led 'led_status'
        option name 'STATUS'
        option interval '50'
        option sysfs 'db120:green:status'
        option default '0'
        option trigger 'netdev'
        option mode 'link'
        option dev 'eth0' )

        echo "255" >
/sys/devices/platform/leds-gpio/leds/db120:green:status/brightness
fi

Can anyone help me to solve this.

Regards,
John
