GS308EP trunk port configuration
Hello,
I know the concept of vlan and pvid and have the following configuraton.
advanced 802.1q
vlan 1 - T U U U U U U U
vlan 10 - T U E E E E E E
vlan 20 - T E U U U U E E
vlan30 - T E E E E E U E
vlan40 - T E E E E E E U
port 1 is the only port in vlan 1 and also trunk port, every vlan traffic through parent switch and gateway is fine. Is vlan1 configured correctly? I googled around, vlan documented well
even screenshot included but not a topic mentioned detail about trunk port.
My question:
- Should I tag trunk port? I throught the other vlan alread done tagging packet.
- port 2 ~ 8 is not in vlan1. what should I do about them? untag or exclude?
Thanks for your help.
Should I tag trunk port? I throught the other vlan alread done tagging packet.
A trunk can consist of a single network link (for example an Ethernet link) or can be made up from multiple network links combined into a LAG.
The tags are marks for identifying the VLAN where the network frames belong to.
On a trunk, you either have all VLANs tagged, or one VLAN which can be operated untagged (with the PVID set accordingly, so the switch knows which VLAN these untagged frames are belonging to).
Tags are applied to the outgoing frames on the switch - these are not implicitly or magically forwarded.
port 2 ~ 8 is not in vlan1. what should I do about them? untag or exclude?
Exclude of course - unless you need that VLAN 1 on a different port (say an access port for the VLAN 1, or tagged e.g. for connecting a wireless access porting configured accordingly).
port 1 is the only port in vlan 1 and also trunk port, every vlan traffic through parent switch and gateway is fine.
So one can assume the parent switch and the gateway is configured accordingly, for handling all the VLANs.

I understand now. I check exclude on vlan1 port 2 ~ 8 and everything works great. I was afraid that I have to factory reset if I mess up.
Thank you very much.
