VLAN setup on SF302-08P switch

ken.watkins
Level 1
Level 1

I have the following setup using two SF302-08P PoE switches:

1st floor

=========

Switch #1 <-------> private network

          <-------> public network

2nd floor

=========

Switch #2 <-------> private network

            ....    public network (visible but devices can't connect)

I have tried to make the config in switch #2 identical to switch #1, but something is still wrong.

Is this most likely a VLAN setup problem, or what?

Thanks.

Hi Ken, the interfaces between the switches need both vlan on the port.

example

vlan 1

vlan 2

port 1 connects to port 1 of the second switch

config t

interface gi01

switchport mode trunk

switchport trunk allowed vlan add 2

The ports between switches need to be native vlan untagged, all additional vlans tagged. In my example, 1u, 2t.

Hi Ken, this looks correct. The links between the switches should be 1u50t. Any port that needs a vlan 50 IP address should be 50 u while any port which needs vlan 1 address should be 1u. All uplinks between devices should be 1u,50t.

Tom,

Thanks so much for your help. In my case, the second VLAN is VLAN 50. Here are the pics of what I think you are talking about through the web interface. Do these look like what you are suggesting?

Thanks again.
