Hi everybody. My apologies but I'm only average at best with my CISCO skills. I have simple setup running a few network devices connected via 3 CISCO switches. It's small office and there are two rooms - one with servers and one with printer and pc's. Each room has 8-port SG200-08 switch.
Router/ firewall is Sonicwall TZ215 and it handles internal routing between VLAN's. Each SG200-08 was connected directly to TZ215 (no SG200-18 yet) and VLANs were working perfectly. Please see diagram below...
Problems started when I added in the middle larger SG200-18 to handle extra devices. Whatever I'm doing wrong but I can't make VLANs work anymore. Something I'm not setting up correctly in SG200-18.
Please help me to setup VLANS here - tagged, untagged, PVID, trunk........ I'm completely lost and already had to reset SG200-18 twice.
My working setup without 18 port switch was like this.
SG200-08 (1)
g1 Trunk 1 1U,100T
g2 Trunk 1 1U
g3 Trunk 1 1U
g4 Trunk 1 1U
g5 Trunk 1 1U
g6 Trunk 1 1U SERVER3
g7 Trunk 100 100U SERVER1
g8 Trunk 100 100U SERVER2
SG200-08 (2)
g1 Trunk 1 1U,50T,200T
g2 Trunk 1 1U
g3 Trunk 1 1U
g4 Trunk 1 1U PC1A
g5 Trunk 1 1U PC1B
g6 Trunk 50 50U PC2A
g7 Trunk 50 50U PC2B
g8 Trunk 200 200U NETWORK PRINTER
Thank you in advance.

Hello,
Oh I am sorry. I understood you have 3xSG200-08 and 2 of them with the same config :-). So no need to use this port for now.

Hello,
Small switches would remain untouched but 200-18 needs to have the following settings:
g15 Trunk 1 1U,100T
g16 Trunk 1 1U,50T,200T
g17 Trunk 1 1U,50T,200T
g18 Trunk 1 1U,50T,100T,200T
Sonicwall now would have only one port connected to SG200-18 with settinngs matching port g18 on big switch.
If you notice there is a change as now you would have only 1 port connecting your network to the Sonicwall, would advise you to use port 17 or 18 since they are uplink ports.
If you have tried to connect two ports to big switch STP would block one of the ports.
Let me know how it is going :-)

Aleksandra, thanks a lot for your help. Just a little bit confused here as to what am I connecting to G17 on big switch (18 port).
g15 Trunk 1 1U,100T
g16 Trunk 1 1U,50T,200T
g17 Trunk 1 1U,50T,200T ??????????????????
g18 Trunk 1 1U,50T,100T,200T
