Creating VLANs in DD-WRT (Part 3)

In the second part of this post I completed the setup of VLANs on my WNR3500L router. To make them available to hosts (and VMs) I now have to configure my Cisco SLM2008 switches.

Fortunately that turns out to be fairly simple. The SLM 2008 has a web-based GUI that does the job nicely. Once logged in it’s a matter of opening the VLAN >> VLAN Settings page. Then just tap in the VLAN ID that you want to create and click “Add”.

This then drops you into an additional page where you choose which ports to associate the VLAN with. I picked all of the ports on this switch (where my ESX hosts are located). Then I clicked “Save”.

It’s just then a case of repeating for the other VLANs that are required. And that’s the switches done. TheĀ defaultĀ configuration of them doesn’t require any further tweaking.

Within vSphere, the configuration required should be obvious. Here’s a screenshot from my ESX host with a portgroup called “Test” defined.

It has a VLAN ID of 6 and one VM in it with an IP Address of 192.168.6.41. It can reach the router’s primary network, the internet and be contacted from my main network and wireless clients.

Exactly what I want for now.
