    1638p randomly rebooted

    robert New Member

      We have a 1638p running firmware 18.03.01.00

       

      Today it randomly rebooted itself.  Is there anything I can look at to find out why?

          It seems like a firmware bug or memory leak.  We had another one reboot.  The last time they were reboot was 7 weeks ago.

              @robert - Thanks for posting your question. Usually, ADTRAN Tech Support requests that you retrieve the following information and open a ticket with them to investigate further:

               

              - Exception reports that are located in1638 flash.

              - 1638 configuration.

              - Output to "show version" from the 1638. This will contain a core dump string that will be helpful to ADTRAN Engineers.

               

              You can open a ticket in several ways:

              - By web - Create a Service Request

              - By emailing support@adtran.com

              - By calling 1-888-423-8726

               

              I would also recommend downgrading your firmware to 18.2.5 on the 1638 as that is the latest maintenance release and has the most bug fixes available.

               

              Let us know if you have any further questions.

               

              Thanks,

                  I downgraded to 18.2.5 as suggested.  However, I was suprised to find out that I could no longer access the web gui after.  Aparantly it disabled itself and I had to enable again using cli.  If it reboots on it's own again, I'll open a ticket.

                      @robert -

                      Beginning with AOS version 17.09.01, the syntax of certain commands was modified from previous AOS versions by either removing or adding the IP keyword. In general, when the ip keyword appears in a command, it signifies that the command is only applicable to IPv4 functionality. As more features introduce IPv6 support, the ipv6 keyword is added to signify the command is only applicable to IPv6 functionality. The ip keyword has been removed from several commands to signify that the command has both IPv4 and IPv6 functionality.

                      Due to this syntax change, downgrading firmware may prevent some newer command formats, which are not backward compatible, from being accepted on startup.  Please issue 'show output-errors' after startup to see which commands failed to load and need to be reconfigured in their old format.

                       

                      Thanks,

                      Noor

                          Thanks for the info.  Any tips on fixing these errors?

                              @robert - These commands would need to be re-entered as below:

                               

                              router(config)#ip http server

                              router(config)#ip http secure-server


                              Keep in mind that once you upgrade code, these commands will automatically be converted into their new format. The format for these commands as of 18.3 is the following:


                              - http server

                              - http secure-server


                              Let us know if you have any further questions.


                              Thanks,
