Hi

I would like to know what is the impact/ limitation for a network load if i do used 1x RB4011 and 2x hub CRS305 in 10g, with multiple devices.
The main router being the: RB4011iGS+5HacQ2HnD and connecting to the 10g port : 2x CRS305-1G-4S+IN in chain, in hub mode.
So is the rb4011 will be enought to pass all traffic, like if 4 pc do a 10g transfert in between them, is the pc#5 doing a 10g connection will cause a noticable drop in speed over the other ongoing transfer ?

And i guess, all thoses gig port will not be causing slowdown, like if an extra 3gig of load is present ... (no vlan stuff present anywhere) the presence of of gig device will not bother the whole network ?

Thanks in advance to help figure out

Hi,

I am not quite sure what you are asking, but here are some answers.

The RB4011 is not powerful enough to route 10G (and doesn't have the ports to do it really)

From the test results section of the RB4011 page: https://mikrotik.com/product/rb4011igs_ ... estresults
From these results the 512 byte routing with 25 ip filter rules (the commonly used value) is 2.56Gb/s
So a Wan connection of 1gbe would work likely pretty well. (1 up, 1 down, and some spare)

If you have 10G devices attached to the switch, and they are talking to each other at 10G, that would normally be ok
and not affect the RB4011 (or other devices) much.
However if they are also sending a LOT of broadcast and multicast packets that go to all ports and require every device to look at it, it could potentially cause slowdowns, (possibly major)

If you have the switch filled with traffic, attempting to push extra traffic through the switch will have to cause something to go slower.
It's all 10G, so you will likely have to try quite hard.
