@Shawn-GSSupport424 Have you fixed the VLAN upgrading issue on this one?


no we haven’t, our test lab cannot reproduce this issue, we are still trying to reproduce it for debugging.


Is there anything I can do to help? There might be specific configuration issues with my network that cause this.


Go with Ticket and provide id here (or PM to @Shawn-GSSupport424) .


If you can use port mirror feature on your switch to mirror all the packets (in and out of your DP75x) to your PC, and run Wireshark on your PC to capture all the packets and PM to me, I can take a look at the captures to see if i can find out the reason.
I would need your enable the Syslog to DEBUG level before the capturing. and please send me your configure file along with the capture. you can PM me the files or just upload it here:slight_smile:


sorry, why don’t you update the template
in Configuration Template it is not there yet.
