I agree with everything George said.

Once you've gone through and fixed the onesy twosey updates that need to be done to get everybody to the same level, then using autoupdate becomes the best way. Instead of CNUT updating 4 or so SM's at once, each AP can update 4 SM's at once. So it's a force multiplier and it makes a big difference when you need to update hundreds of units.

I've always used the 'use access point as file server' option. I assume yours is set the same. What that does is upload the boot image for the configured SM platform revision (P9, 10, etc) to the AP. The *AP* then sends the image down to the SMs (via RF private IP) and reports progress back to CNUT (which is what the "update application address" is for on the AP's general config page). If you have multiple platform versions selected, it will start at the top of the list, and cycle through them every 20 minutes. 'Order by SM number' is helpful, but I usually just do things half manually. Like I know x AP has only P10 SMs registered, so I turn off everything except P10. Or I'll go tower by tower and enable auto-update on a 4 sector cluster and wait for all SMs to finish, then update the APs and move on to the next.

The last time I tried 'Update Entire Network' ungood things happened.

So anyway the problem there is that the AP doesn't care what version the SMs are running, it just pushes the image to them. If you need to update specific SMs to a certain version, then the only way is to manually add their management IP address to CNUT.

Checking or unchecking the SMs in the CNUT auto discover list does nothing more than allow you to select them to remove them from the list. Other than that, it's purely informational, such as auto-update progress which the AP reports back with SNMP messages. That list is simply the AP's LUID table.

It's not necessarily bad the way it works, it's just not good. Your situation though, I don't know what to tell you other than... don't fall so far behind on updates? ......... ducking. The main problem I have is the guys "finding" SMs in the trucks and they end up being really friggin old. Like a 450 the other day on 12.1.2 or something like that. I said, no, bad dog, find another SM. Not my problem that you can't keep your truck organized.

I’ve been using CNUT for 9 years but am a newbie at SM Autoupdate because I thought it wouldn’t work if you checked Public for the IP address. When I enabled Autoupdate for the AP, CNUT immediately started updating all the SMs it discovered under that AP, without me checking the boxes or even telling it to update anything. Which surprised me. It sounds like you are saying you can check the boxes for which SMs you want the AP to autoupdate, but that’s not what I observed. What am I doing wrong? In the past, I have always given CNUT the IP address of each SM, and checked the boxes for which ones I wanted updated. I’m trying to learn how to use SM Autoupdate. The manual doesn’t seem to be helping me a lot.

    What George said.

    However.... You can sort by version number,check all the ones at
    the top of the list (version A), upgrade them to B, then do it
    again and upgrade everything to C.

        It does not understand upgrade path. It will update every SM
        on the sector to whatever version is enabled and highest in
        the list for that platform. For example, if you have 13.2.1
        on top, then 14.1.2 below that, both checked, it will enable
        auto-update with 13.2.1. You need to manually add only the
        SMs that you want to update.

        Or somebody tell me I'm wrong, because that's always the way
        it has worked for me.

            Let's say I have an AP with various SMs that are on FW
            versions A, B and C. Perhaps new installs got sent out
            with C on them, but the upgrade path requires that you go
            A -> B -> C, and some older SMs have been taken to B,
            while some are still on A.

            Is there a way to upgrade all the SMs on A to B, without
            downgrading the SMs on C back to B?

            I could be really brave and enable both B and C in Manage
            Packages, and hope that CNUT understands you can't go
            directly from A to C so those SMs should be updated to B,
            but the ones already on C can stay there.  But I don't
            trust CNUT to be that smart, or I'm not that brave.
