GS1920-48HP v4.70 VLAN issue
Hello everyone and please give me your opinion on this problem. I am trying to set up a simple input and output VLAN with number 5, but the configuration is misbehaving.
I have a device connected to port 1, untagged port vlan 5. On the output untagged port 45 vlan 5. I set a static IP address on the end device behind the port 45 and the VLAN does not work.
I only found the problem after exporting the configuration. VLAN 1 on ports 1-50 remains untagged even though I have set forbidden VLAN 1 for ports 1+45. If I manually edit the configuration and remove VLAN 1 untagged on ports 1+45, saved config import -> it suddenly works fine. How does this problem arise please? Thank you

The config view is not that clear when it says untagged
fixed = part of the VLAN
untagged = if its tagged or untag even if forbidden which if forbidden is forbidden and not part of the VLAN.
Sounds confusing better to view the GUI
in your case for:
VLAN1
forbidden 1,45
fixed 2-44,46-50 untag
PVID set to 1 for 2-44,46-50
VLAN5
forbidden 2-44,46-50
fixed 1,45 untag
PVID set to 5 for 1,45

Hi PeterUK, thank you very much for your response. I have attached some screenshots of the GUI. From the settings it shows that VLAN 1 is set as forbidden on the ports, but in the export it still shows as untagged. Am I doing something wrong please?
I only expect an untagged port when I set fixed without tx tagging.

you now need to go to VLAN Port Setup and set port 1 and 45 to PVID 50

This is also done, should i check anything else please?0

That should be it? did you mean to set tag on ports 49-50?
as said the export listing for untagged is not what you think it means0
