Switch SF300 create vlan

[elliotmollman]

I've been having some trouble configuring a new set of vlans on my SF300, both in the terminal and web GUI. I have tried both, also this is my first time configuring a switch. Here is what I have done so far:

#Created vlan 2 with access ports 1-3 assigned for host usage.

#Created vlan 3 with access ports 22-24 assigned for servers.

I want the vlans not to be capable of communicating with one another, and they are on the same subnet 192.168.1.0. According to my understanding, access ports are used for hosts and trunk ports are used for switch to switch connection when trunking vlans, or switch to router. This is why I have port 12 as trunk, since it is my router connection. My problem is not having any internet on my vlans, no matter what I do. I tried adding the vlan 2 and 3 to the vlan 1 membership on port 12. I'm looking for a better understanding on how to give internet connection to my vlans.

Thanks!

• If you want to configure a VLAN on a Cisco SF300 switch, there are a few things that need to be done.
• First, you need to create the VLAN itself. This can be done in the VLAN Management menu.
• Once the VLAN has been created, you need to add it to the switch. This can be done in the Switch Configuration menu.
  Lastly, you need to add the VLAN to the appropriate ports. This can be done in the Port Configuration menu.

I have 2 vlans already created, both with 3 access ports. I have a picture of what my current configuration looks like. But I'm wondering why I'm not getting any internet on my vlans.

You created two VLANs and the access ports to them look fine. The trunk port looks strange to me, but it should pass traffic from those two VLANs nevertheless.

However, first of all, you should have separate subnets in each VLAN. Then, you need to be able to route traffic among those subnets. Without that, you will not be able to access Internet from multiple VLANs. Depending on where you set up inter-VLAN routing, the router or the switch, you may or may not need a trunk. You will need a trunk only if inter-VLAN routing is done by the router. Otherwise, access ports can be used. If you need a trunk, bear in mind that a trunk is a link in which ports on both sides of the link need to be set up exactly the same way.
