SG250 VLAN auto change with unknown reason

[vanness629]

Dear Sir/Madam

I have a strange issue with the vlan on SG250.

I have a proper vlan configuration, and disable gvrp.

but my vlan config will auto change after reboot.

for what I find now, it success to load the vlan config during startup.

but when it detect the upper level switch, the vlan will auto jump to other setting.

I have no idea why and would like to see if someone can provide some idea to me. 

Thank you

Hello, 

I have disable the smartport already.

I also try to disconnect all the other network port and reboot it, and still remain the same

Hello,

I have solve the issue, the Administrative auto smartport disable is not means the smartport disable

when I disable the smartport one by one, the issue was solved.

yes when you disable globally the config should effect all port, but some time config already available in port may be that is the issue i guess. glad you able to resolve the issue with the suggestion. we mark as resolved now.
