  • 1.  Switch status hung on "Not in sync - Pushing config"

    In classic Central, I have a stack of 2 x 6300, running v. 10.13.1161, in a UI group. Today, I made a minor change in the config then instead of syncing normally, the status stayed in "Not in sync - pushing config".

    I tried the following:

    • remove my changes.
    • remove auto-commit and push the changes manually.
    • ssh to the switch, disable Central wait for the switch to appear offline and enable it back.
    • Make another little change and push the changes manually.
    • Re-enable auto-commit.
    • Wait a little more in case I wake up and all is fine...

    Next step would be to restart the stack, but that will require a maintenance window, as this our main core switches. Any other ideas of what I could try, any service I could restart without causing service interruption ?  I also saw suggestions in the forum to move the switch to another group and move it back but I would like to avoid that if possible.

    Well...I was on the phone with someone from TAC for an ticket on another issue, and I wanted to show him the problem with the sync status. Guess what...my switch was now synced ! ... after a few hours. 

    One of those days...

    Actually its not one of those days. It happens. I have reported issues to engineering before on sync issues. You wont get any assistance from the lower guys and you will need ERT to assist as they have the ability to look at back end sync issues on central. 

    There was either 1 of 2 problems that existed. Most likely your device was not syncing before you made the change. There was nothing locally with your device that was wrong if it was connected to central and you were getting stats. These are just things that we have to accept with having our services in the cloud by any vendor. 

    From my understanding there are a couple different services or components to central with AP's and SD-Branch. You have your config sync, monitoring and stats, and then orchestration and routing topology. The switches would not be part of the orchestration and topology as they do not build a vpn tunnel and exchange routes with overlay. Since there are different modules, there are also different groups of public IP's that go with those modules. 

    You could have had a routing issue going to some of those ip's, the other issue is there could have been a back end service that someone else already reported to ERT and was in the process of fixing. 

    When I had a config sync issue on some 9012's 1.5 years ago. It took 1-2 weeks to get a resource on the phone form ERT and then get it to engineering. Once it was handed off to them it was fixed pretty quickly. 

    Next time if there are any sync issues. Just make sure you have basic internet from your gear and its connecting to central and you are getting updated stats.

    I have had similar issues.  Sometimes I would leave for the day and the next morning everything was fine.

    Thanks for your comments guys. This was the first time I experienced this behaviour.

    Another thing to keep in mind is that some hiccups have also happened with the addition of new central (cnx). We have seen some days where classic central has all sorts of issues. I dont really want to be discouraged from cloud services at this time. There are quite a few changes happening. Just keep in mind that ERT has the ability to check back end logs and submit internal requests to engineering. As long as you can prove that you dont have an issue with tcp/443 traffic, you should be able to push for a back end issue with ERT.
