AP SSO FUS upgrade ???

mscherting — Sun, 04 Jul 2021 08:13:44 GMT

Hi all,

I'm preparing to enable HA SSO on a pair of 5508's; one with an HA SKU and one with a 50 AP license. I noticed that the bootloader's and FRIV's are different, even though the firmware versions are the same.

Should I apply the AIR-CT5500-K9-1-7-0-0-FUS.aes to the HA WLC before enabling AP SSO, or will the peering process take care of this for me? Thanks!

Yes you should make sure the FUS is upgraded and identical prior to enabling AP SSO.

Thanks. I was a bit nervous about reburning the firmware.

You should be fine, the important thing is to disable AP SSO.

Scott F. You mention disabling AP SSO first. Maybe this is restating what you just said but I have a scenario where I have two 5500s running FUS 1.7 with AP SSO enabled. I want to upgrade to FUS 1.9. I had heard that you could run the FUS upgrade just like the image upgrade, in other words allow the primary to send the code over to the standby using redundancy links.

Can anyone confirm if the FUS upgrade works the same way and the code upgrade? Or do I have to disable AP _SSO and then do each controller indovudually?

TIA

Don't think that will work since this is a boot image upgrade. You can open a TAC case and confirm, but you can try and see if the HA gets the image. If it doesn't, then you know that you have to install it separately.

Ok thanks. Just opened a case. I'll reply to the thread with their answer.

Received this from TAC. Looks like you have to break SSO ---> upgrade FUS code ---> then enable SSO again. -Enjoy

Regarding your questions the answers are above:

-The upgrade of the FUS image behaves the same way as a normal controller code upgrade.

There is no different procedure than upgrading the controller but as it is FUS image which is independent on each controller you will have to break SSO and install the image on each controller and then bundle the controllers again after the upgrade.

Yeah... Didn't think that would push. Well enjoy the fun:)

What about forcing the standby controller into maintenace mode? Maybe it lets me initiate SW download then. Since the new FUS only updates bootloader and CF stuff it should be fine... at least I hope so.

1) Disable Uplink of standby, standby moves to maint

2) Reenable Uplink, push SW and reboot

3) Install FUS and reboot into standby mode again

4) Do switchover

5) Repeat steps 1 to 4

But I'm out of office now until april possibly. I will report back then. Maybe someone has some input on this?

I would stick to the instructions and break ap SSO. Your safer that way.

I was told by TAC that the FUS upgade could be done with AP SSO enabled.

Do you know if that stance has changed recently? I was told that it would be treated just like a typical code upgrade and that the image would be pushed over to the standby controller....

Scott Fella — Mon, 03 Mar 2014 20:07:56 GMT

Well... if TAC told you that, then I would try it and see.... heck.. you have it in writing, so you can blame them if it doesn't work.

Thanks,

Scott

I was told the same thing. But honestly it did not work for me. I actually escalated it to a Lead and then the Manager to get the answer that I posted in here. I think when dealing with TAC depending on who you get first level, your mileage will vary.

I did see that post, but it seemed to contradict what I was told by TAC.

I can't argue with that There are a lot of TAC engineers that are great that's out there... not saying that there are bad one's, but some have more experience than others, which makes them great.

Thanks,

Scott

Last week, I upgraded four WiSM-2 AP SSO pairs from FUS 1.7.0 to 1.9.0 using GUI.

The same method to upgrade the firmware is the same "reaction" you'll get, i. e. you GUI into the active use and use TFTP (didn't try FTP) to transfer the FUS code across. The active unit will push the FUS down to the hot standby unit. It sort of give you an indication where the process is and at the end, it gives you the link to reboot (or save and reboot) the WLC.

It will take about 25 minutes (I timed it) to boot up both pairs.

Re: AP SSO FUS upgrade ???

OGB — Wed, 05 Mar 2014 14:11:43 GMT

Did you boot them one at a time (so that the APs remain operational) or both at once?

Re: AP SSO FUS upgrade ???

Scott Fella — Wed, 05 Mar 2014 14:45:29 GMT

Leo mentioned to me that he rebooted one at a time.
