Hap AC3 lan ports leds

Hello. I noticed that on my hap ac3 lan leds do not act like on old hap ac2 where i can see the difference between port/activity. they are blinking very slow and seems not related to interface activity. Here is my config.

/system leds
set 0 disabled=no interface=ether1 leds=led1 type=interface-activity
set 1 disabled=no interface=ether2 leds=led2 type=interface-activity
set 2 disabled=no interface=ether3 leds=led3 type=interface-activity
set 3 disabled=no interface=ether4 leds=led4 type=interface-activity
set 4 disabled=no interface=ether5 leds=led5 type=interface-activity

To you the behavior is the same?

With those settings LEDs should work properly. They should stay solid and flicker quickly once in a while if the cable is plugged in and active on both ends. What rOS version are you using and are the LEDs active while the cable is not plugged in?

I am using ROS 7.1.2. Same was with 7.1.1.
I have 4 cables connected, the light came on when i plug the cables, this is not the problem, only traffic activity is not show on the blinking, they blink very slow and not in real connection with the trafic amount.
