I am a beginner on Aruba, but I well know others manufacturer Wifi products.
I am testing Aruba products in Aruba OS V6.1 (A620 + AP105 + AP93) with SSID in "bridge" mode.
it appears that "bridge" mode have less features than "tunnel" mode (user derivationrule for example).
Does someone have a document or can explain me the features differences between the two modes ?
Hello here you will see more information about that topic of Bridge mode in campus mode in which i think you are referring to
Page 41 and 42
Also this is what it says on the user guide
User guides does point you a list of features you loose on bridge mode page 803
Most ArubaOS features are supported in all forwarding modes. However, there are a some features that arenot supported in one or more forwarding modes. Campus APs do not support split-tunnel forwarding modeand the decrypt-tunnel forwarding mode does not support TKIP Counter measure management on campusAPs or remote APs.

Hi,thanks for your reply.
the list is not complete, you can add:
- User derivated rules
- firewall rules logging to syslog server
I am disapointed, it will be difficult to deploy 802.11n architecture with hight throutputs (video), or optimized data management (VLAN RADIUS attribut) because if I want these features I must use the "tunnel" mode and concentrated all the data flows to the wireless controller. The controller could be the bottleneck of my Wifi network.
Just curious, but have you done any throughput testing that shows that the controller is the bottle neck?
Are yousure derived roles does not work?
Because they are working just fine on bridge mode on my lab...
I also got many deployment in which they want to put the controller on IDC.... which is located obiosly not in their central or remote branches
The thing is that to not saturate their link to the IDC i explain them how does the solution work and i give them the option of putting the APS on bridge mode.
Some of them tell me no there is no issue put them on tunnel mode... or other clients just tell me well i got slow links ill need you to put it on bridge mode...
The thing is that on the VRD this scenario does not exist so i dont have any aruba recommendation fo rhtis specfic scenario....
I do point them the list of features they loss.
It does not appear on that list but you can add DHCP fingerprint.... it doesnt work on AP Campus bridge mode... at least that what is says the documentation of fingerprint
I was concerned about the controller being a bottleneck in my environment too... but when I looked at the interface on the controller I found that it was only averaging about a 25% load - with occasional peaks.
This is on a site with about 100 APs and 1000 clients doing everything from Facebook to Netflix.
Link doesnt work
