At moment I have three vlans configured on a Dell PowerConnect 2724 managed switch. I use the three vlans to seperate parts of my home network.
I'm faced with problem when trying to access the web management interface of the Dell PowerConnect 2724. It can be only configured to vlan one and cannot not communicate with the other vlans to provide internet access. So the only way I can configure the settings of the switch through the graphical user web interface is through a dedicated laptop which is only connect via ethernet cable to another port on vlan one.
I've tried to troubleshoot this problem by attempting inter vlan routing. My technical knowledge is a bit limited so I had attempted to connect a ethernet cable from a port on vlan one to a port on vlan eight. This method appeared work. I was able to access the PowerConnet switch's web interface through the web browser of a computer connected to vlan eight but for reason beyond my technical knowledge my internet access from vlan eight was unresponsive. I was not able to access my router or any other websites from my computer until I removed the ethenet cable link between the two vlans.
It appears I’m encountering a broadcast storm when inter-crossing the two vlans. Is there away anyone can recommend to properly route between the two vlans without experiencing this network interruption?
If anyone can assist me in troubleshooting this problem it would be greatly appreciated.
I look forward to hearing your comments.
To route between VLANs you need a device that can handle layer 3, with the 2724 only being a layer 2 device it won’t route between them on its own. Depending on your router you may be able to configure port forwarding on your router to tell requests from the other VLANs to connect to the management IP. When you connected the two VLANs together with a cable did you set them to trunk mode to transmit tagged frames or were they sending untagged traffic.
They were set to send - out untagged traffic. I believe for the Dell power connect 2724 you are unable to set tagged ports for vlan one.
The main router I have is a consumer wireless one. A Linksys EA6400. I do have a old wrt54g with dd-wrt flashed on it, which I was trying to use to route traffic from vlan eight to vlan one. I was able to access the Web management interface from vlan eight but experienced the same problem which appears to be a broadcast storm or loop which results to a completely unresponsive network.
Yes doing that will create a broadcast loop, to communicate between VLANs you need a layer 3 switch.
Thank you for your help, but do you think I would be able to use a standalone DD-WRT router to achieve inter vlan routing? Is there a way to connect a route from a physical port on vlan-8 to a DD-WRT router then to a physical port on vlan-1 without creating a broadcast loop or storm?
The dd-wrt router might be able to do vlan routing so that the management ip address could be accessed from any vlan. The switch doesn’t support spanning tree protocol, which is what would prevent broadcast loops, and isn’t designed for the VLANs to be able to communicate.
I'll give it another try, if not I guess I'm pretty much stuck using just a dedicated laptop to configure the switch. But thank you again for your help. One more question though, do you know any good resources or links regarding inter vlan routing? I not exactly sure the steps on configuring it or what type of commercial routers really support it. Any affordable enterprise/commercial devices you would recommend that might be able to rout between the two vlans?
Here is some general information on our vlan routing. http://www.dell.com/downloads/global/products/pwcnt/en/app_note_38.pdf
We don't have anything that is not expensive that will do it.
Most have another layer 3 switch in the network that handles the intervlan routing and the ones that I have seen that don’t use some remote desktop software to remote into a computer on VLAN 1 and use that to access the GUI.
