Re: [AFMUG] downgrading pmp100 radio

I factory defaulted a P10 5400SM that was running 12.1 and took it up to 13.1.3 without an issue. No error about version mismatch. Then I took it down directly to 11.2 and got the version mismatch after the reboot verification, but it is running 11.2 just fine. No FTP errors either. So yeah, something is just different to/from 11.2 with CNUT 4.9.18 and the version mismatch thing, but it seems that I can't reproduce your FTP update issue. I did factory default it though. Are you sure your user/pass and SNMP read/write matches in the CNUT network element config? If so, I think you should hit up Cambium and see what they say.

Could be an FTP passive thing. If it's not that, then you'll probably want to hit up Cambium support. If I have some time this afternoon, I will mess with a couple radios on the bench and see if I see the same.

I noticed the other day that CNUT 4.9.18 complains that 13.1.3 DES 
"version doesn't match" after updating some SMs from 11.2. The radios 
all updated fine though.


Craig, can you post the exact error messages here?

    There has been a CNUT upgrade since then. I needed the newest

    Last summer, using whatever was the latest version of CNUT at
    that time, I was doing just that, downgrading from 12.1 and
    13.1.3 to 11.2 no problem.

    You're saying you can go up but not down?  I wish I could tell
    you what version of CNUT I was running, but I'm certain it was
    brand new in June or July.  Haven't needed to do this since
    though and have long since moved up to latest version of CNUT again.

    I have never had to do this, but I need to downgrade a p10 sm
    that is running 12.1 to 11.2 and I can not get it to work.  Maybe
    I am doing it wrong.  I just load the 11.2 package and hit
    upgrade right? I get some sort of ftp error after cnut does say
    it starts the file transfer?  I upgraded to the newest cnut, same

    issue, I upgrade the sm to 13.1.3 and I still cant downgrade it? 
    Am I missing something?   Thanks, Craig.
