Mikrotik RB3011

Hi how many clients and connections cant support this routerboard, i have a local network with around 2000 users and the traffic maximun is about 100mbits in high load times, this roouterboard can handle thath traffic??

Unfortunately, there is no clear “yes” or “no” answer.

The answer depends on a lot of factors and the number of clients is one of less signficant ones of these factors. And as I’ve tried to explain when responding to your previous topics on the same theme, in your particular case, the firewall configuration is far from optimal for throughput.

Sadly, only after spending the effort to optimize the configuration you can find out whether it was worth it or not. No doubt that optimisation will speed up your router, but the question is whether it will speed it up enough, i.e. to a point where the router will not be the bottleneck any more.

yes, i optimize all the thinks that you tellme, remove the passtrought on the mangle rules, but the problem is this, is certain moment the trafic going to 0 and return in one second look the picture and the CPU is arround 70-80% on nearly 90mbits of traffic

I have it configured as follows, all the devices are around 20, they are on a slplink model sl2452web switch, there on the same switch I split the ports using vlan ports (separate each port forming a kind of independent switch between them) for each port only see the port giga 1 and do not see each other so avoid the broadcast, and port giga1 goes to the port eth1 of the routerboard, and from there the traffic to the port eth2 of the same routerboard where it goes to the servers, this is the configuration that I have, and in another port of the routerboard comes the cable from another part of the switch where there are 8 ports that are in another ports or divided ports so that they do not see each other, this is how I have formed the network some advice?

That one-second gap could be caused by the CPU being overloaded with some housekeeping task which would normally pass unnoticed but as the CPU is already at 80 %, it breaks everything, or by a hardware fault, or by a software bug.

Without fasttracking most of the traffic, I’m afraid it is impossible to reach higher throughput. Even with fasttracking, you’ll probably not be able to reach a full gigabit. But fasttracking is incompatible with use of routing-marks. I hazily remember it seemed to me that you could avoid using them and use /ip route rule instead, which does not interfere with fasttracking.

Can you post the updated configuration?


None which would lead to decreasing the load on the Mikrotik, as none of it comes from bridging, it all comes from routing.

As the CPU is at hight usage you have to check who is using it and then to search for a solution. Please go to Tools>Profile, set CPU at all and click start. There you can check who is using cpu resources, post a result here!
