VLAN newbie


I want to switch from netgear to cisco so I bought a SG200-26. I was able to set up VLANs on the netgear, but somehow I have trouble to do it on the cisco. Searching the forum and the internet didn't helped me. Ich think I understand the VLAN configuration, but... well, I have the following config:

I added one additional VLAN: 233 (=subnet) and configured it on two ports:

Interf.      Mode     Admin-VLAN     Operational-VLAN

2     general     1U     1U

3      general      1U,233UP    1U,233UP

4      general      1U,233UP    1U,233UP

Port 3 is connected to the subnet xxx.yyy.233.zzz with a working dhcp-Server. On Port 4 ist a win7 Laptop with dhcp configuratrion on. The laptop is not getting an IP. :-(

Traffic shoud flow between 3 an 4, right?

I administer the switch from Port 2 with an Laptop manually set to

Best regards

the port 3 where the server is located should be a trunk port( with native VLAN 1) and port 4 should be an access port in VLAN 233.

Hi Alain,

thanks for the quick response. I wasn't able to test it, because they (higher level IT) disabled my network. They have a BPDU guard active. The STP was active on my SG200, so my port was immediatly disabled.

My goal is to have 3 or 4 different VLANs/subnets on the switch. They do not have to talk to each other and every VLAN will have an "upstream" link. There will be no other switches, just servers or NAS attached to the SG200.

Can I prevent the switch from sending BPDUs (on the "upstream ports)? When I deactivate STP and RSTP?

or can I have STP enabled and just set "BPDU Handling" to "filtering". It is unclear to me wether "filtering" means incoming or outgoing packets.
