Wireless Access

Hi,

Currently were are deploy  Aruba 7010 standaalone controller with 17 Aruba 505. Controller uplink to Core Switch using LACP 2Gb port. The SSID using tunnel mode uisng wpa2. The internet speed is 1GB. When we do speed test or ipert we only can get around 400mbps speed for upload and down.  If we change the ssid to bridge mode tje speedtest or iperf we can get 600mbps. Also we already try enabke drop multicast also same. Is this limited for tunnel mode? We also already try with decrypt-tunel the speed also same around 400mbps. Is it any tunnel feature that can cause this different?. Is there away to improve wifi speed in tunnnel mode.? Or is  this beacuse of controller 7010? Current firmware version is 8.10.0.7.

If you are trying to optimize the tunneled throughput you'll need to make sure that jumbo frames are enabled and allowed between the AP and controller.

Hi,

Do you mean we might to enable the jumbo frame at controller (firewall enable jumbo processing and controller port), then AP in  default ap system (SAP MTU) and switch port to AP and Controller?

At least have jumbo enabled on the switch ports-VLANs that connect to the AP, controller, and any links that are between switches on the path between AP/controller.

The point is that tunneled traffic adds a few bytes for the GRE tunnel and if it exceeds the MTU at any point in the path, packets may be dropped or fragmented, resulting in degraded performance.

The key thing is that unless jumbo frames are enabled all the way between the AP and controller, a feature of 802.11n and above networks, A-MSDU, will be disabled on the SSID. A-MSDU makes transferring data more efficient, so with it disabled it will be slower than with it enabled. 

You could try putting the SSID into decrypt-tunnel mode for comparison. With decrypt-tunnel, the encryption/decryption of user traffic is done at the AP, and A-MSDU will be enabled, even if you don't have jumbo frame capability between the AP and controller.
