Hi,
I'm running a little WISP network. About 10 towers, total 300 customers. And a total BW of 600/600 Mbps at the moment. We use Ubiquiti AC gear and AirFiber and ccr1009 router at the head end. The big problem is pointing at our switchs . We use ToughSwitch from Ubiquiti and it comes with performance problem. Anyway We want to replace them by Mikrotik Gear



Package Mbps:

5/5
10/10
25/25
50/50
100/100

VoIP is comming this year and Live IPtv


So the question is what do you guys suggest :

-8 giga ports
-24 giga ports




Do you need more informations?

Thank you for your help and support!

I have also recently shifted to Mikrotik gear, and I think after seeing your post, that shifting to Mikrotik is what you need. I have a very similar setup.

However, I'd hope some senior member of this problem can recommend you with better settings.

I don't understand how a switch can have performance problem when doing switching...
Maybe you need something else then a switch.

I've heard that the ToughSwitch had a lot of problems. One of my clients has one, and it regularly stops responding to ping. Still seemed to work but I didn't mess around with it, just replaced it.

Well, i think its buffer problem, flow control.


About my littles towers:
https://routerboard.com/CRS112-8G-4S-IN
Is the crs112 can do the job in for my little tower?
Spec sheet : 400mhz cpu and 128 of RAM. Is it enought ?
What does the switching result and ethernet test result mean?

And our bigs towers where we have a lot of clients:
Is the cr-125 can handle up to 1gbps of BW ?

I realy dont know how to choose the right gear. Thank you!

The CRS range will switch at wirespeed. The CPU only becomes an issue if you want to do routing. What may be an issue is the feature set, eg the CRS125 can't do access control lists at the switch level. Also, the configuration is quite a bit different to most other switch brands, so take the learning curve into account.

thank you.

I only need a switch that can handle enought BW.

switch need to work well with VLAN.

At the moment there is no VLAN on the network, but for future services : VoIP and IPtv we certainly need VLAN.

Thank you guys!

A MikroTik switch will handle as much bandwidth as it's ports can support. So if you have Gigabit ports, each will work at full Gigabit speed. This is why it is called a switch basically. So choose any MikroTik Switch with the number of ports that you need, and it will take 100% of the bandwidth that you throw at it.

It helps. Thx


Do you mean for exemple that the crs125 24 ports can handle up to 1gbps per port at the same time?

While in switch mode, yes! The traffic will just go from one port to the other, through the switching chip, directly and with no processing. If you will do routing with it, or any filtering, then the traffic goes through the CPU and the operating system works with it, then it will be slower of course.

wonderfull.


But i still dont understand why switching result page show lower value :

Switching Non blocking Layer 1 capacity 37,202.4 50,000.0 5,874.1 50,000.0 2,031.9 50,000.0


thank you

In Ethernet, packets are seperated by IPG (Inter packet gap) usually 20bytes

so on small packets
64byte packet -- >20 byte gap -->64byte packet -- >20 byte gap -->64byte packet -- >20 byte gap,

so while you using 100% of link speed (Layer1), only 3/4 is actual data ( Layer2)

With larger size packets this ratio is much better.

Thank you very much all.
