Configuration of switches for a VLAN
Hello, I'm trying to configure network VLANs for something like this: The idea being is that VLAN1, VLAN2 and VLAN3 all have access to the internet via the router but none of the VLANs ...
Hi,
Not using this configuration by choice but constraints with physical wiring.
So, after reconfiguring as per schumaku post, I connected wired connection in to switch3 port 4 to test VLAN3. The first thing I noticed was that the autoassigned IP address was in the range of 192.168.168.x but was expecting something in the range 192.168.1.x as this is what the DHCP server on the router uses. So I presume it has lost the DHCP server functionality as there is no connection to the router???
I therefore manually set the IP address to 192.168.1.35, the subnet to 255.255.255.0 and the gateway to 192.18.1.254. With these manual settings, I cannot ping the router or access the internet.
Is there something I've missed or testing I should be doing differently?
Thanks

It's not the physical wiring prohibiting a true 802.1q VLAN config. A true VLAN segregated config would have three VLANs, making up a dedicated network, coming with a dedicated IP subnet each, offering a DHCP for each network, and requiring a router handling the routing between the VLANs, and doing the many2one NATing for each IP subnet to the Internet.

On one hand, I'm not the geek nor happy to promote these asymmetric VLAN configs - said that: I could be wrong with m understanding here. On the other hand, my ad-hoc notes could have lead to incomplete or wrong configs, too.
Would you mind to show screenshots of the port config (informative with the named purpose of the ports), VLAN, and PVID configuration for VLAN 1, 2, and 3 from all switches? Without, it's digging in the dark.
Hi schumaku
I'd be more than happy to provide screenshots of the configuration but before I do, I'll ask whether I'd be better off buying a GS110TPv3 switch and replace switch_2 with it so that it looks something like this:
Seems like it may solve a lot of messing around as this 'more managed' switch will be better than the 'slightly managed' switches and will be easier to understand when changes need to be made??? It would save some wiring too so there are less physical changes.
I've actually had to change the 5-port switches for 8-port switches as I needed a couple of extra ports :smileysurprised:, but other than that there are no changes as I've tried to keep everything else the same!!
My main concern is whether the GS108eV3 switches will allow a mixture of VLANs on each port (like switch_1 has VLAN1 & VLAN2 and switch_3 has VLAN1 and VLAN3).
If this is equally as difficult then I'll go ahead and provide screenshots as requested.
Thanks

The asymmetrical VLAN configuration is very similar (resp. the same) on the Plus (GSxxxE) and on the Smart Pro (GSxxxT) switch lines.

It's by far not on each port - the VLAN x lines show for each port "t" for [t]agged, "u" for [u]ntagged, and "-" for no membership.
Sounds like I am better off with the configuration I have then :smileylol:
With regard to the configurations, I believe this is the information you asked for each switch:
