How to configure a spare led to show WDS activity

This guide will help you setup a new led to report activity on the WDS segment of your LAN bridge, just like the other ports in the Ethernet bridge. Tested on a TP-LINK WR1043ND with v.12.09, some changes might be required. Config and script are my work.

1. configure WDS as shown here: http://wiki.openwrt.org/doc/recipes/atheroswds

2. identify a spare led (I chose QSS) and edit /etc/config/system (directly or via UCI) accordingly:

config led 'led_wds'
        option name 'WDS'
        option sysfs 'tp-link:green:qss'
        option default '0'
        option trigger 'netdev'
        option mode 'tx rx'

3. place the following script under /etc/hotplug.d/net as 20-led-wds:

#!/bin/sh
# WDS led configuration script for OpenWRT
# Author: Andrea Borgia <andrea@borgia.bo.it>
# License: GPLv2

CFGNAME="system.led_wds"
LED=`uci get $CFGNAME`

if [ "${LED}" != "led" ]; then
        logger -t WDS Missing led configuration
else
        if [ ! "${INTERFACE##wlan0*.sta*}" ]; then
                logger -t WDS Interface: $INTERFACE / Action: $ACTION
                if [ $ACTION == "add" ]; then
                        uci set "${CFGNAME}.dev"="${INTERFACE}"
                        uci commit
                        /etc/init.d/led start
                else
                        uci set "${CFGNAME}.dev"=""
                        uci commit
                        /etc/init.d/led start
                fi 
        fi
fi

As soon as the WDS node comes online the wlan.sta* interface is configured as the led device name; when the node goes offline, it will be removed once the timeout expires and the wlan.sta* interface goes down. Reboot and enjoy
EDIT: added "*" in the wlan interface test, to catch secondary SSIDs on the same radio.

Please edit your post and use code tags. Makes it much more readable :-)

hi, great,

thanks for the script.

I wonder where shall I look the other lights?

option sysfs 'tp-link:green:qss'

Check under /sys/class/leds on your router: those are the leds recognized for your architecture.
