  1. Rene,

    I have a Cisco SG300-28 PoE+ switch and am having an old age moment in setting up VLans. Would you know the answer to or be able to assist with the following:

    My network has:

    1 router, which also handles DHCP duties with one range currently specified 192.168.1.x/24
    1 switch
    1 WAP
    and about 40 nodes

    I want to create multiple VLANS on the Cisco SG300 switch.

    Vlan10 - Mgmnt
    Vlan20 - Children
    Vlan30 - AV
    Vlan40 - Automation
    Vlan50 - VoIP
    Vlan60 - Guest

    What are the steps necessary after creating the Vlans in this scenario to make things work?

    WAP is on port 1

  2. Hello Dinh.

    I had a production network where I wanted to implement exactly what you describe. The solution I used was access lists as you mentioned. It is probably the fastest and most immediate solution. However, there are a couple of other solutions that may be more flexible as well. These are described below:

    VLAN access list - This is just an access list but it filters based on VLAN rather than IP. It is a layer 2 solution. An example configuration can be seen below:

    interface Vlan1
    no ip address
    shutdown
    !
    interface Vlan2
    description VLan connected t

  3. Hello Brian

    Please allow me to step in and participate, as this is an issue that I had trouble in visualising and understanding. I hope I can be of some help. For the most part, you’ve got it, maybe I can make things a little bit clearer for you.

  4. Hello Arindom

    There are two fundamental differences between your config and mine. Your config is what is called a “router on a stick” where the routing takes place in the router itself. This means that any traffic from VLAN 10 to VLAN 20 for example will go to the router, be routed from the Fe0/0.10 interface to the Fe0/0.20 interface, be sent back to the switch and to the appropriate device on VLAN 20.

    My config involves interVLAN routing, which is routing from one VLAN to another within the Layer 3 switch itself. In this case, routing takes place from one

  5. Hi Nityanand,
    this “L3” written over the line means that both link end-points on switches are routed ports. We can add one more link interconnecting switches, make both of its end-points routed ports. Bundle links together, add IP on each end-point of port-channel and then run OSPF over it. It is no problem, should look like this.

    Create virtual port-channel interface, make it routed port-channel and add IP on it.
