LCD Interface: Max Speed?

I didn’t see any documentation for the LCD Interface Max Speed setting in RouterOS 6.19:

No matter what I set it to [4M, 4Mbps, 400 kbps, 400bps, 4, 400, 4000000] it always says “Error in Max Speed- bitrate expected!”.

I assumed that it would set the vertical scale of the interface graph to fixed but if that’s the case it doesn’t seem to validate or work. If not can someone point me to the documentation for this?

Thanks,

yep, it’s broken in WinBox, use Telnet (I didn’t check the WebFig)

Open a terminal and type

lcd interface print

to list your interfaces then use

lcd interface set "your-interface-name" max-speed=2.4Mbps

Of course replacing your-interface-name and 2.4Mbps with your values.

It appears that it will validate n.nMbps, Kbps, bps without any problems. You can verify that it’s validated and set by printing again or in Winbox, although if you open the interface for editing it in winbox even the set value will appear invalid.
