7925g perform poorly in Aruba Wireless environment
I'm having a lot of performance issues in our VoWLAN, we have deployed Aruba 7210 Cootrollers running 6.3 OS with APs 105.135, 225 and 124, 134 and 224 with Cisco 7925g Cisco phones. Our Voice SSID work in 5ghz (802.11a). Cisco switches behind are 3560 and 3750
We loss the voice stream during sessions (call), sometimes call can't be answered and one-way audio ramdonly too. Most of the phones with one or two exceptions has SNR higher than 35 and the health% which is a new parameter in Aruba OS 6.3 is super high also in most of them, with not less than 50%, but btw 70 and 100% in most of them. However we see a lot of retransmission frames in both ways to/from clients, even in phones with super high numbers. The coverage in the building regarding RF great, and phopnes with APs on top of the user's desk (without romaing) has the issues above described. We also has a lot in Aruba infrastructure and change all APs and controllers to cisco would very costly at this point.
We have followed the recommendations for the controllers config from Cisco, but still continue having the isues and have been troubleshooting for a long period already. Any one that has had the same problem around? How did you guys fixed?
I don't think it was .. Let's see if JC responds. I helped JC on this one and what we captured was uapsd issues. For both sides on a phone Cisco and Aruba and it really didn't go anywhere.
