Cisco 3560 to SG200 VLAN trunking

I need desperate help with my limited Cisco knowledge. I am setting up a VM lab I need to do vlan trunking between my Master L3 WS-C3560V2-24TS-S switch to SG200 L2 Switch .

I have setup a couple of vlans in the master and I would like the sg200 talk to these vlans. I have tried at least five different possible solutions and no luck so far. The sg200 is only web based, No CLI supported. I will attach screenshots from my sg200 and txt from the 3560 config file.

To start my project I would like to only start with Vlan 224 and be able to talk to this vlan from the sg200.

Cisco gi0/1 is connected to my Comcast router with a 192 Network DHCP
Links Between: Cisco 3560 Interface gi0/4  to SG200 GE26.

The device should now be access through the DHCP address, find this by looking up the server or doing an nmap scan and look for Cisco equipment.
Now create the VLANs you need and name them under the "Create VLAN tab".

The created VLAN/s now need to be added to the desired trunk port on the smart switch, this is done through "Port VLAN Membership". Simply select the trunk port, edit the details and select the VLAN that is to be allowed on the trunk, tick Membership and then click the arrow to move it in to the selected column.

The VLANs that are needed on the trunk should now be showing on the Port VLAN Membership page.

Access ports can now be configured, which is straight forward by changing the required ports to access ports and defining which VLAN is required, which is done through "Interface Settings". This won't actually work until we configure a trunk port on the other switch.

Depending on your native vlan settings, you may have to change the management vlan setting before changing the port on the other switch to a trunk. Just a reminder make sure the management vlan is a member of the trunk port. This can be done through the "IPv4 Interface".


The smart WS-C3560V2-48TS-S switch might be unconnectable if the management VLAN has been changed, therefore we need to enable a trunk port on the other switch to gain access again.
