There is 3 switch chip in the RB1100AHx4.
On this page: https://wiki.mikrotik.com/wiki/Manual:Switch_Chip_Features we see chip limitaion:
Each switch chip can support up to 2048 hosts.
Does that mean that we have a limitation of 2048 devices on ether1-5 + 2048 on ether6-10 + 2048 on ether11-13 ?
Or there is no limitations, only the performances will decrease?

It is true, each switch chip has 2048 host limitation. Using SW bridge removes this limitation, but it can impact performance, because bridge uses CPU resources.

Thank you for your answer.
With this configuration, I will be using the Bridge so I won’t have this limitation of 2048 users?
/interface bridge add name=bridge1 vlan-filtering=no

/interface bridge set bridge1 vlan-filtering=yes
How many devices can be supported without decreasing performances?
With these features on:
50 FW rules
OpenVPN

More generally how many users can the RB1100AHx4 support in bridge mode ?
The CPU limitation is 5k,10k,15k connected devices ?

@hugal , did you find out the answer to your considerations? Further more … your config shows VLANs and RTL8367 switch chip reportedly doesn’t support VLANs in HW, how did you get around?
i think with more than 2.000 users on this router the last thing to worry about is switch host limit
if you need switching for that amount of host get a switch, and let the router do their job as a router
i thing rb1100ahx4 can attend several thousands of users but with a simple/optimal config and with maximum 1gbps of traffic

The bridging/switching is then most likley done in software/cpu.
