Poor performance

Hello

 

We just recently setup our 3200XM controller on our network. We have multiple SSID's each assigned a Vlan, I have all the Apple TV's on one SSID, 31 of them.

 

So we can connect to the Apple TV's no problem from the other SSID's but the performance while watching say a youtube video when mirroring from an iPad is poor the video keeps skipping. But if your connected on the same SSID as the Apple TV there is no issue or latency.

Re: Poor performance

Hi,

 

is the Apple TV VLAN is different from all SSID VLANs ?

 

is there any QoS options enabled on the SSIDs ?

 

what is the expected number of users connected to non-Apple TV SSID ?

 

is ARP to unicast enable for each VAP ?

 

is BC/MC per vlan interface/SSID enabled ?

 

is Drop Broadcast and Multicast optimization enabled in SSIDs ?

 

is there wired clients connected to same SSIDs VLAN ?

Re: Poor performance

is the Apple TV VLAN is different from all SSID VLANs ? Yes

what is the expected number of users connected to non-Apple TV SSID ? About a 100

 

is ARP to unicast enable for each VAP ? Yes

 

is BC/MC per vlan interface/SSID enabled ? BC/MC Rate Optimization?  No

 

is Drop Broadcast and Multicast optimization enabled in SSIDs ? No

 

is there wired clients connected to same SSIDs VLAN ? No

Re: Poor performance

Do you have enable air time fairness?

do you ahve many g clients on the enviroment?

 

Try enabling all Abi is advising you!

 

How many SSIDs you got?

Try not having more than 3 as it impact the performance...

 

do you  have link aggregation between controller and the switch you plugging it?

 

If you dont maybe you are consuming more than the only giga you got in there and you getting a bottle neck.... and if you don thave QoS for streaming video it will be worse...

Re: Poor performance

Also

Do you have this AP connected to a Gigabit port?

If you dont know you can always look at the AP, if the light of ehternet is AMBER it is connecting to 10/100...

Even if you know that your port is a gigabit ethernet port Check if that lights is not amber.... because if its is, then it syncronized to 100...

If so then you could have a bottle neck tehre...

Re: Poor performance

Hi tattony,

 

Try enable (Drop Broadcast and Multicast) in VAP and enable (Broadcast-filter ARP) in Advanced-> Firewall tab. (this option should be enabled per controller)

 

I am afraid that if Apple TV is using Multicast, it would be dropped and quality became worst ! :S ... if that the case then undo the previous step and enable (Multicast automatic shaping) in Advanced->Firewall tab.

 

hope this would help.

Re: Poor performance

Ok will do but I will have to wait until school lets out today I will keep you informed thanks for everyone's help.

Re: Poor performance

Hello check if the AP is connected to a gigabit ethernet you can do it through the controlller

 

#show ap debug system-status ap-name Server_Room | begin Ethernet

 

Server_Room is the name of the AP just change it to the name of your AP

 

Check if its connected really at 1 gigabit speed

Re: Poor performance

I do believe it is connected to a gigabit connection all lights are green we have 21 Access points and we have 6 SSID's

Re: Poor performance

Yep if all lighs are green in all APS then they are connected to gigabit...

About the SSIDs aruba does not recommend having a bunch of SSIDs.... im attaching you a documentation about this so you can read it,  might not main issue but its countributing with the problem.
