To ALL: We also are moving to ArubaOS version 8.2.1.1 this summer, but we are a little further along. We have 6,000 access points (as mix of 214,215,314,315,325,324,205h,303h) and 8 7240 controllers. We upgraded to the 7420xm controllers and did a hardware appliance for the mobility master/standby. We currently have 4 nodes up in a production cluster with about 3,000 ap’s on it. We are scheduled to complete the move by mid july.
For the most part it is working fine. It takes a while to get used to the new design/commands/config. We have found that there are still some bugs in the mobility master GUI and it is difficult to do certain things with the GUI. We built the mobility masters from scratch and used 90% cli. Most of the commands are the same as version 6.x so once you understand your hierarchy it is easy to move stuff over via the cli. The cli is your friend. We have ran into a bunch of issues configuring interfaces and port channels in the gui so that is all done via the cli. We do configure vlans, vlan interfaces, etc via the gui. Once everything was built I do most changes/tweaks via the gui (system profiles is the main area to work in) but I still build the VAP and WLAN via the cli as it is just too difficult to do in the gui. We also had to re-organize/re-design the overall system to take advantage of the clusters. I combined subnets, made them larger and spread them across all nodes in the cluster. Airwave is another issue as there is no way to split clusters across airwave servers and we have two. So we are going to end up with unbalanced airwave servers, one for each cluster. We also bridge some wired vlans through the controllers to get the “experience” and that seems to be working fine (as long as you exclude the vlans from the cluster). Airgroup seems to be your pain point in version 8 right now. I have heard version 8.3 has a bunch of airgroup issues and we have a case called in for 8.2.1.1 for airgroup. We are trying centralized with Clearpass so your mileage may vary. We also ran into a bug with clerapass sending down a timer with a coa, the timer would expire but the coa would not work, still open. But all our users seem to be happy and work fine for the most part. We are doing to stick with version 8 and hopefully get the few issues worked out before semester start. I do feel this is the summer to do it. From: The EDUCAUSE Wireless Issues Constituent Group Listserv <[email protected]> On Behalf Of Harvard Townsend Sent: Thursday, June 28, 2018 5:47 PM To: [email protected] Subject: [WIRELESS-LAN] Aruba version 8 (Mobility Master) and AP-115 access points For those of you with Aruba wireless infrastructure, what are your experiences with running ArubaOS version 8.X plus the Mobility Master architecture with AP-115 access points? HPE/Aruba is telling us that model is supported (confirmed in the ArubaOS 8.2.0.0 release notes) and they are not aware of any issues. However, I heard from an Aruba reseller that a number of their customers, both commercial and higher ed, had significant issues when they upgraded to 8.X and moved to the mobility master architecture. We purchased the MM license and want to make the jump to 8.2.1.1 from 6.5.3.4 this summer, but are hesitant given the rumor. Have any of you experienced problems with AP-115s and Mobility Master?
