“Finding good code for these controllers is tough. Sometimes it feels like you have to pick your poison with these things.”
Amen to that. Even more frustrating- what constitutes “good code” varies depending on whether you ask your SE, TAC, someone else at TAC, yet someone else still at TAC, or the community forums where the exalted Partners and VIPs get more information on such matters than us lowly end users. Very often the partners’ opinions differ from TAC’s. For the market leader, this is almost a decade now of running insanity when it comes to wireless code.

We run an Active/Standy HA pair with SSO. We would get the following message: #PEM-1-SETNAME: pem_api.c:8310 Unable to allow user <username> into the system - perhaps the user is already logged onto the system? and a similiar message for 802.1x users. Basically the system thought the users were already logged in because the controllers were out of sync even though using the "sh redundancy" tools from the command line showed no issues. We would have to reboot the controller for it to go away.. TAC verified the issue was a bug (don't have the exact bug ID) and released to us 7.6.122.5 which has been stable so far. This all happened at the end of June. Every now and then a controller would reboot as well.

We have a lot of 2600, 3500 series AP's and some legacy 1142 and 1131's. We are thinking about moving to 7.6.120.0. Has anyone had experience with this version ? Any issues? recommendations?
