Guys, I'm not trying to be rude but this is a forum for people on the CCIE Wireless track. All discussions about how other products work should be done outside this thread. If this were an interoperability question I could understand but this seems like a comparison. Thanks in advance!

The Aruba can run in "tunnelled mode" like the cisco ap's or what Aruba called bridged mode which is similar H-REAP or OEAP. The Tunnelling is different though as the Aruba access point can setup GRE (on the LAN) or IPsec (WAN/Internet as copied by Cisco and called OEAP ;) ) to tunnel the data packets back to the controller. The 802.11 headers are not removed by the Aruba access point but are de-capsulated at the Aruba controller. I think what your friend may have been referring to with the distributed work load in the Aruba example is the Master/Local/Local branch scenario where the controllers are distributed across offices/buildings/subnets and the access points terminate their tunnels to their "local" controller.

I just want to ask if this is true. WisM - All data are tunneled to the WisM but data processing are being done by the core switch. All AP are just sending information to the controller NO data processing are being process by the AP. Aruba - Data processing or distributed workload are being used. Not all data are reaching the controller and most of the data processing are being done by the AP. Is this true?

Normally you will have (in a large deployment) master and local controllers but the master is not necessary. You can have multiple master and local controllers backing each other up (mostly using vrrp). All the tunnels terminate on local controller but the master distributes most of the config to the local controllers. The local controllers could be "local" to the master or at a branch office. Basically though the "default" behaviour of the Aruba controllers and access points is similar to the cisco controllers and access points. That is excluding the Layer3 and "firewalling" capabilities of the Aruba controllers. cheers Andy -----Original Message----- From: Manolo Encelan Sent: Monday, August 13, 2012 9:55 AM To: [email protected] Subject: [OSL | CCIE_Wireless] Cisco Controllers vs Arouba Hi Guys, I know this is not the right group to ask this question but I would really appreciate if you could give some light on this issue. Cisco controllers vs Arouba: What's more better in terms of handling users data traffic? Network Information: - Network setup is Collapse Network. - 1 Wism2 controller inserted inside a 6500 core switch. - 500 AP manage by the Wism As to my understanding (correct me if I'm wrong) that all data gathered by the APs will be process at the core switch while the Wism will just manage the APs and the users. And somewhere in the future this could break the 6500 switch :(. I've checked Arouba controller and I found out that all data processing are done not on the core switches but at distribution layer. One big point for Arouba. I'm I right? Thanks in advance.
