We are going to upgrade our WLC 5508 with 2702i APs from release 8.3.141 to release 8.5.140 In the release notes there was information regarding "WLAN Poller", se below link:
It was referenced from one of the links under "Upgrading Cisco Wireless Release" in the release notes.
Is it anyone who has used it, and is it necessary before upgrading?
It is not necessary. Recently I did the same upgrade with tons of 2700 with no problem.
-If I helped you somehow, please, rate it as useful.-
Yes have used it, and had issues when I did an upgrade where it was not used and i hit the flash corruption issue before this script was available which was one of the first cases to identify the issue.
The polling script will make sure you do not have any APs with Flash corruption issues.
If you do the upgrade without doing it and do hit a flash corruption issue you will then have to recover the APs via tftping a new recovery image to the AP
If you have a support agreement, log a TAC case to go through it with TAC before your upgrade
FYI for planning:
When we ran this against a WLC with close to 6000 APs it took a few hours from a Linux host, and nearly a day from a MACOS.
Look at the script as you can select if you want it to reload APs or not
Just curious as to what Linux OS you used to run it? I've got a CentOS 7 box I'm trying to get the script going on and I'm having no end of issues just getting it unpacked and installed to begin with!
Wondering if I should just call it quits and use a W10 VM, problem is I have a LOT of APs to run this against... (thousands)
Hey patoberli thanks for the response!
My Python is v2.7.x (afk, can't remember the specific version!) I wouldn't think it comes down to minor version differences within 2.7 does it? Pip version on the Linux host is 8.1.2 or something where it looks like the pip install used as part of the package is 8.1.1
can you share the output of you terminal/ command prompt that you get when trying to run the poller
you can also look at setting up a new Python Virtual environment
I would recommend using a Linux or MACOS host to run it off based on past experience with Python and Windows, I also found the time to run the poller on windows vs Linux was massively slower on windows by multiple hours.
Also tghe host running it needs the ability to SSH all the AP IP addresses and WLC
