Hi guys, there is another "issue": many switches expose control of LEDs, but the control sometimes comes in groups. For example you have 3 LEDs for each port on a 5 port switch, but 2 of the LEDs cannot be enabled at the same time (the ethernet cage connectes them on different polarity on the same signal pair). Or you can set port1-port4 LED 2 to blink on link activity, but this you can only enable by this group of 4 leds. How to solve this in the hw triggering api? Marek
