Hi there,

 

I'm re-building a larger scale network, trying to use TP-Link-Business Switches.

 

The "ingress rate limit" Parameter, found under

Port Profiles --> Advanced Options --> Bandwith Control --> Rate Limit

on the controller

is NOT working correctly !

 

The "egress rate limit" part works perfectly fine, though !

 

Details:

 

Having a Central OnPrem hosted Omada-SDN-Controller, works fine so far.

 

I need to restrict the bandwidth usage on some ports, using the "egress rate limit" and the "ingress rate limit",

found in the Port Profiles --> Advanced Options --> Bandwidth Control --> Rate Limit

If change the setting in the profile it gets immediately and correctly pushed to the switch ports that profile is assigned to.

I cross-checked this on the switch through the cli.

 

The devices on those ports are used as internet stations - with different download/Upload speeds.

I can test it by making a speedtest, having different settings on the port.

The "engress" parameter defines the download speed (going out of the switch)

The "ingress" parameter defines the upload speed

As there is 10Gig-Internet uplink in the background (YES !) I get results of 990-997 MBit/s in BOTH directions, if I run without any limitation (Interface speed = 1 GBit)

This is OK.

Applying "egress Bandwidth limit" works fine.

e.g. 50 MBit restriction gives 48MBit Download --> OK

 

Applying "ingress bandwidth limit" works badly.

e.B. 50 MBIT restriction breaks the speed down to 1,4 MBit

and other reproducable wrong results.

 

There is a firmware bug here !!

 

Seems to be a rare usage case, but I would need it urgently !

 

Thanks for help
