Hello, I’m an engineering student and I hope you can help me: I’m using GNS3 and simulating the image of the mikrotik I’m setting up a network topology that contains Vlans, among it there’s a voice VLAN and a video VLAN, the rest is data, I’m doing an access mode and a trunk mode. My problem is how do I perform QoS in this topology and how can I see if it works QoS in video and voice because I am using 8 machines and 1 router and 2 switch.
My question is how can I see if voice and video QoS works or what do I need to see it working. That is, do I need to virtualize the voice or the video?
Thanks, I hope you can help me.

I use GNS3 as well… as far as i know you can deploy a virtual machine of your choice so that you can test at least the Video… search for windows appliance…
then I must use a virtual machine to virtualize the video and VoIP?
then I must use a virtual machine to virtualize the video and VoIP?
Yes thats what i think…
By the way, what is the topology above ?
I’m sorry I published twice, I thought the first publication didn’t have a clear idea. 
Now I’m studying mikrotik so I don’t have much knowledge.
The topology that is there is what I am working on, but I am still modifying it and using vlans.
Then I will apply Queue Tree to make QoS
Testing with GNS3 in this case is not helpful, since creating queue trees on the switches will not be suitable for this type of setup - queue trees will require that you disable hardware switching on those switches, and then they can only handle around 100Mbps total which is probably not enough (nowhere near wire speed).
You need to use the QoS in the hardware switch chip, and the configuration is different on the CRS226 vs the 326. The 226 supports prioritization so you can do the QoS you want. The 326 doesn’t, all you can do is rate limit, so you have to rate limit all of the VLANs except your VoIP to leave enough remaining for the VoIP.
The queue tree setup will work on the CCR1072, it is powerful enough, and it is probably the only way you could effectively do it on that device. But basically this means that all three devices will have completely different QoS configurations, and with GNS3 you can only really simulate the CCR1072 configuration.
