    Firmware R.10.7.0 problems...

    neonettech New Member

      Hi,

      Yesterday I upgraded the firmware of several switches to R.10.7.0 and ran into several odd issues.

      The setup is the following:

      A (NV1534 2nd Gen) <-> 2.5GB fiber <-> B (NV1534 2nd Gen)

       

      B is connected via two port-channel connections (2xCat5e each channel) to C (NV1524) and  D (NV1544).

       

      D is connected to E (NV1224ST) via port-channel (2x Cat5e).

       

      I updated the firmware on A, B and D yesterday to R.10.7.0 because D was a new switch we installed yesterday and the NV1534 were still running 18.03.01.00 so I thought updating the firmware would be a good idea.

       

      After the update odd things started to happen - the port-channel to C would show as working but I could not ping C nor could I access the web-interface of C anymore but that worked when I unplugged one of the two Cat5 cables.

      The other odd thing that happened was ping times to A and B (while connected with a PC to A) were jumping from 120ms to 390ms with every third packet being dropped. The whole network throughput was rather unbearable.

       

      We have about 50 computers on the network and 2 VLANs - one office VLAN for all computers and servers, one iSCSI VLAN for a NAS device and two Hyper-V servers - these VLAN's are only on A and B where these devices are connected to.

       

      I ended up rolling back the firmware on A and B to 18.03.01.00 and everything went back to normal.

       

      Any idea what the problem is? I made sure that I downloaded the correct firmware for A and B - 2nd generation, the new firmware seems to work fine on the NV1544.

       

      Could it be a performance issue with the firmware being more demanding on the hardware? Does the 1544 have a faster CPU and should I perhaps use that one for the iSCSI and the Hyper-V servers?

       

      On another note - I also updated the firmware on a Netvanta 7100 a week ago and after the update my Windows 8 laptop would no longer be able to access the Internet though it. It was working fine with the previous firmware - but after the update packets coming from my Windows 8 laptop would be blocked by the firewall. The Windows 7 and Windows XP machines didn't have any issues. Even an iPhone and a Windows 8 mobile phone was working fine.

       

      Any input would be appreciated.

       

      Thanks,

          Frank - Thanks for posting your question on the forum.

           

          Unfortunately, I am unable to say for sure what caused the issues you were seeing. If I understand correctly, though, switch D is still on R10.7? Although I do not see a reason why switch B would not be able to perform in its role,  I would probably swap switch D and switch B. The 1544 is a more powerful switch as compared to the 1534 and would be better suited as the core switch. Another suggestion I would make is attempting to upgrade switch A and B to R10.5.2 (as the time of this post, this is the latest maintenance release) and seeing if you experience the same issues.

           

          Either way, I think this particular situation would be better handled in a support ticket.
