rate control on internal users?

Hi Everyone,

I would like to know if its great practice to rate control internal users in a school district? I've done, the obvious answer to rate control our guest network and such but I'm questioning the internal side where bandwidth/air-time is shared between students and staff members? We currently have an excellent internal line with Download/upload speeds that wont be overloaded so I'm only concerned with making our internal WiFi work as best as possible without limited users etc. Any ideas?

Rate limiting is rarely a good idea, the best practice is to use QoS appropriately and to not rate limit ;)

According to support they recommend me to do rate limiting because having multiple firewall policies on the AP's can cause more CPU utilization with such a density deployment

Are you actually seeing high CPU usage from having separate user profiles (and associated QoS and firewall configuration) or is this a hypothetical concern?

We were having constant issues with our 1x1 deployment and T3 suggested that I remove my firewall policies within the AP configuration since we could not locate the issue from months of troubleshooting. So they suggested we go rate-control limiting.

We were having high CPU issues at one point which is why they recommended to remove the policies.

That still doesn't answer my question. :P I'm not doubting that you had high CPU usage, rather was it being caused by user profiles, associated QoS, firewall rules?

I'm just noting one of the things they did in order to removed CPU concerns because at one point they were high in my deployment. I personally did not think that was causing it but i went ahead to took the advice from the professionals at tech support.

I personally think it's likely to be a suboptimal approach, and you should consider using user profiles and QoS instead of rate limiting.

I presume the APs in question are the CPU and memory constrained AP121/AP141s or older?

Have you updated to HiveOS 6.5r3 on all your APs?

ok well, I'm not concerned about the guest WiFi, I'm more concerned with the internal side and the reason why I posted this question is because I wantd to plan ahead for our state PARCC testing so students will be able to take the tests without any issues. So if QoS is what you're recommended then how should I go about that?
