Q:
VLAN help, routing?
VLAN, Routing, PowerConnect, Layer 3 switches
I have some Powerconnect 6248 Layer 3 switches that I'm working with. I've never worked with VLANs before so I'm totally lost here. I don't know CLI so I'm using the GUI. I have workstations and servers set up on 192.168.0.x/255.255.255.0, workstations on 192.168.1.x/255.255.255.0, and workstations on 192.168.2.x/255.255.255.0 Switch1 is going to be 192.168.0.x Switch2 is going to be 192.168.1.x Switch3 is going to be 192.168.2.x Switch4 is going to be 192.168.2.x I have VLAN10 set up on S1 and VLAN20 set up on S2, and VLAN30 will be on S3 and S4. How do I get machines in VLAN10 to communicate with machines in VLAN20, VLAN30. (ping, file share, etc) I set port 1 to trunk but that doesn't seem to be working. I'm hoping someone familiar with these switches can help.

Hi,

For these vlan to communicate, you got to have at least one trunk in which these vlans will flow and communicate. Most of the time, this trunk is connected to the gateway(router or any layer3 device).You have to create subinterfaces on the router or any layer3 device for this vlans to flow on the trunk you created. Its like building a huge tunnel<trunk> and inside this tunnel are small tunnels<subinterfaces> wherein the vlans will communicate. So even if they are in different subnet, they have something in common, and that is the trunk that this vlans flow.

Wow. Ok, that makes sense. Can you tell me how to do that?

Right. These are layer 3 switches so they should be doing the routing. What I have right now is port 1 set as a trunk on switch 1 and switch 2. That is to say port 1 on each switch is a member of VLAN10 and VLAN20, etc. even though s1 doesn’t have any other ports assigned to VLAN20 and vice versa.

Switch1 (vlan10) has a pc with the following configuration
192.168.0.35
255.255.255.0
192.168.0.230

Switch2 (vlan20) has the following pc configuration
192.168.1.30
255.255.255.0
192.168.1.230

Right now the PCs cannot communicate with each other.
If I assign the one pc the same gateway as the other PC they can communicate. So something is wrong there and I don’t know what it is.
