Hello everyone,

 

I started to create a VLAN and I am discovering some network issues since the change. (Slow internet, no internet, no connection to router)

 

Situation until a few weeks ago:

 

My setup is like the following. 

I have a Unifi Security Gateway Router behind my Modem in which I only used the default Network (no VLAN).

 

Switch 1 TL-SG108E (Hardware Version: TL-SG108E 5.0 Firmware Version: 1.0.0 Build 20191021 Rel.53360)

Port 1 for the Router connection

Port 4 unifi Access Point

Port 3 connection to Switch 2

 

Switch 2 TL-SG116E (Hardware Version TL-SG116E 1.0 Firmware Version: 1.0.0 Build 20180523 Rel.52122) 

Port 1: Connection to Switch 1

Port 9 Unifi Access Point

Port 15 Connection to Switch 3

 

Switch 3 TL-SG108E (Hardware Version: TL-SG108E 6.0 Firmware Version: 1.0.0 Build 20201208 Rel.40304)

Port 1 Connection to Switch 2

Port 2 Unifi Access Point

 

All devices used the same network with IP Adresses 192.168.0.1/24 and one SSID 

 

 

Current situation:

As I use a lot of smart home devices I tried to implement a VLAN for my smart home devices. Therefore I created a new Network in my router with the VLAN ID 10 (192.168.2.1/24)

I also created a Guest network with VLAN ID 20 (192.168.3.1/27)

For those 2 VLANs I created separate SSIDs in the Router connected to the VLAN.

 

Below are the configurations for the 3 Switches:

Switch 1:

VLAN ID	VLAN Name	Member Ports	Tagged Ports	Untagged Ports	Delete
1	Default	1-8		1-8
10	IoT	1,3-4,6	1,3-4,6
20	Gast	1,3-4	1,3-4

 

I tagged the Ports 1,3 and 4 for VLAN 10 and 20 (the connections to the 2 other switches and to the access point). I also tagged the port 6 for vlan 10 because there is running a proxmox server where I want to tag some Virtual Machines with a specific VLAN.

All Ports for vlan 1 are untagged. The PVID is for all ports 1.

 

Switch 2:

VLAN ID	VLAN Name	Member Ports	Tagged Ports	Untagged Ports	Delete
1	Default	1,3-11,13-15		1,3-11,13-15
10	IoT	1-2,9,12,15-16	1,9,15	2,12,16
20	Gast	1,9,15	1,9,15

 

I tagged the Ports 1,9 and 15 for VLAN 10 and 20 (the connections to the 2 other switches and to the access point).

The Ports 2, 12 and 16 are untagged in VLAN 10 as I use Smart Home Devices on those Ports. I also changed the PVID for those ports to VLAN 10.

Those 3 ports did I define for VLAN 1 as "not member". Is this correct?

 

Switch 3:

VLAN ID	VLAN Name	Member Ports	Tagged Ports	Untagged Ports	Delete
1	Default	1-8		1-8
10	IoT	1-3	1-2	3
20	Gast	1-2	1-2

 

I tagged the Ports 1 and 2 for VLAN 10 and 20 (the connection to switch 2 and to the access point).

I set port 3 to untagged for VLAN 10 as this is a smart Home device. I also changed the PVID to 10.

Should I mark this port from VLAN ID 1 as "not member"?

 

Is there anything wrong with my configuration which could lead to network connection issues?

 

Should I not use the default network anymore, create a new network and assign it to a VLAN as well?

 

 

Maybe it is just one setting which is wrong and could solve my issues.

 

Thank you in advance.
