Are you running a recent version of ROS? According to manual , CRS3xx is the only device family which can HW offload MSTP. Could be that this was added in some recent ROS version. Could be there's a bug regarding MSTP HW offload as well. If you're running one of recent ROS versions, then I suggest ...

Hi guys I have some CRS328 switches and noticed that the switch often gets high cpu for no apparent reason.

Hi all Today I receive an E-mail from Mikroitk support team. They told me the issue maybe caused by multicast traffic flooding and urge me to upgrade to the new stable 6.48.2 version because It just release some multicast and IGMP snooping improvements. But I have changed my topology, 2 CRS1036 will...

TheLordOfTheShells

Your posted configuration does not agree with that statement

Because the provision is quite long and have the same configuration , I don't want to make you guys read all of that so I just make an example of configuration. If needed I will show all the provision config.

TheLordOfTheShells

Anything using the WiFi_Data or WiFi_Guest CAPsMAN datapath do not use local forwarding, so the traffic to/from clients using them will be handled by the CPU in the CRS.

First I used CapsMan forwarding and WiFi_Data and Wifi_Office datapath are for that purpose but now I don't use it anymore.

Hi Today I have changed one CRS317 to CCR1016-12S-1S+ to check whether the issue is on device itself or it's because of my configuration.

Hi Sindy
After following your recommendation setup all the ap to local forwarding. My crs317 still have really high cpu. So I want to ask you for 80 Cap what mikrotik router should I use to setup Capsman

Hi Azendale
Have you solved the problem?
Just by not using VRRP and only having one router.

Have the same issue with you on 2 CRS317 Switches running vrrp, I have searched Mik's forum but did not find the wright answer.
Have you sent request to Mikroitk tech support?

TheLordOfTheShells

Hi guys. I setup HA for 2 CRS317 Mikroitk switch using VRRP protocol. Following this wiki article: https://wiki.mikrotik.com/wiki/Manual:VRRP-examples The issue now is the vrrp up and down frequently.

K6ccc could you please explain more.

TheLordOfTheShells

I have enabled IGMP snooping on bridge before I wrote this post. Is there anything else you would like to recommend.

TheLordOfTheShells

For snooping to work properly, you need an IGMP querier. Do you have one configured?

Hi can you give me the example how to configure it ?

Hi Sindy
After checking I found that the issue maybe was not from our CRS317 switch. Packet dropped on only wireless clients, sometime there is no traffic on wireless (Can not ping to our gateway)
I wonder whether it is the Capsman issue?

Yes, I have already created a new datapath for test APs and also see the client on CapsMan now. With 70 APs, did you use the /caps-man provisioning? : Yes, I do. After configuring new datapath I see one interface with this error "possible regulatory info mismatch with CAP" do you know what...

Hi Sindy
Today I just configured some APs for test first but I have some questions hope you will explain it,

Ok, if only one cable have all the traffic of your Vlan 100 on your HP switch, try to connect first the Mikrotik and then your HP Switch, the idea is separate the Vlan 100 network to do the hotspot, then use an unconfigured port on your HP switch to pass the traffic.

Use your HP switch as Layer 2, not Layer 3. Subnets, routing, firewall rules, etc. needs to be on MikroTik. Configure your port of switch that connects to Mikrotik as trunk port.

Let's translate the L2 term "VLANs" to an L3 term "connected subnets", i.e. IP subnets in which the Mikrotik has its own IP addresses. A connected subnet also needs a route; it is added dynamically (i.e. automatically once the IP address/mask configuration is added), with distan...
