Getting DHCP through Dell 6224 VLANs

Hello,

I have a very simple setup in my test lab that I am having trouble getting working.  I have a Dell PowerConnect 6224 (Layer 3) and a Dell PowerConnect 2724 (Layer 2), two laptops and a Windows 2008 server setup as a domain controller.

My 6224 has 3 VLANs setup on it, 10, 20 & 30.

My 2724 also has the 3 VLANs setup on it.  I have a connection from each VLAN on the 6224 to matching VLAN on the 2724.  

I am using the 6224 to be able to route the VLANs, such that they can all communicate with each other.

I need VLANs because we need more IP Addresses than one subnet can provide and to minimize MultiCast traffic on my main office network.

Currently I have all three of my PCs plugged into the 2724 on the three different VLANs.  The domain controller is on a port with all three VLANs, 10,20 and 30 and this port is Tagged on all three.  There is a laptop on VLAN 20 and a Laptop on VLAN 30.  Everything works great.  I was able to add the laptops to the domain, and they are getting DHCP addresses.

The problem is that when I move the 6224 onto my real network, I am going to want the Domain Controller to be directly connected to the 6224, not to another switch.  When I try to duplicate this in my lab it does not work.

I moved the Domain Controller to port 7 on the 6224, gave it access to all 3 VLANs and set them as Tagged.  But when I do that I cannot see the Domain Controller from the laptops.  Am I missing a step?  Can this be done?

Also, I am know unable to access the web interface on the 6224?  Can someone tell me how I do that?

Here is my running config:

Are you able to ping from the 6224 to the 2724?  Or is it just the DHCP that is not crossing over to the 2724 switch.  One thing that may be a problem is you will need to have the same default/native VLAN on both switches in order for communication to pass properly.  

Here are a couple of Community Posts that discuss successful trunk configurations with a 27xx switch.

Right there is no communication between the switches...I cannot ping one switch from the other.

Both switches management is on VLAN1....do I need to make a change to the Trunked port on the 6224 to get it to be sending on VLAN 1?

What port is connecting to the 27xx?

can you provide what config you have on that port/lag only?

Are you add VLAN 1 as tagged/untagged or both as well as the VLANs that travelling across the connection to the 27xx?

I would definitely encourage reading thru the posts that I provided and make sure the 27xx is set up correctly thru the GUI.

On the 2724 I am connecting to port 24 and it is Untagged on VLAN 1.  It will not allow me to change it.

On the 6224 I am also connecting on port 24 and for VLAN 1 my choices are T or F.  It will not allow me to set it to untagged.

I read those posts that you sent and tried those changes.  It did not help.

You may take a look at flipping the switch on the 27xx switch to Unmanaged.  This way it would simply pass traffic thru the switch.  Also possibly updating the firmware on the 27xx switch.  

If these efforts do not resolve you may need to call in for more direct support towards a resolution.

Here is a link for phone numbers to reach Enterprise Technical Support.  Have your Service Tag and Express Service Code ready when you call.

In an attempt to figure this out I have changed my setup a bit.

I removed the 2724 and have replaced it with a 5448 (which is what I will be using in production).  The 5448 has a console port.

I have also simplified my configs.  I have only a single VLAN now.  Here is the config on the 6224:

console#show running-config

!Current Configuration:

This has not fixed my problems.  I am still unable to ping between the switches.  I.E. I do a ping from the 6224 to 172.16.1.253 which is the IP on the 5448 and I get Destination Host Unreachable.

Does this have something to do with Management VLAN?

"on the PowerConnect 62xx series switches, you must use General mode if you want to allow management traffic onto the switch over the PVID.  If you use Trunk mode, you will not have the default VLAN on those ports.  The ports will only allow tagged traffic."

The ping from one switch to another is going to be from the management VLAN to management VLAN. I would change from Trunk to General and set the PVID.

Ok...so i found out that I had an issue with DHCP server.  Once I fixed that, the connections between the 6224 and the 5448 work great.  I know have my VLANs and I am able to do DHCP and put systems on the domain.  Here are the configs that are running:

The 6224:

console#show running-config

So now my next question....we are a company that does Live Streaming Video as part of our product.  So for testing we need to be able to get MultiCast video through the VLANs but only when requested.

Right now if I run a MultiCast video on one VLAN I cannot see it on the other VLANs.  That is good.  However, I need to be able to have that MutliCast Video go to another port on another VLAN if a call is made for it.

I know this has something to do with MultiCast Bridges, but I don't understand the Setup on the 5448.  When I look at the instructions it talks about the MAC Address...but what is the the Address of?  I tried using the MAC from the MultiCast Video device, but it tells me it is the wrong format.

So just to make sure you understand what I am trying to do:

I have MultiCast video running on VLAN 40 right now.

I need to get that Video to one port on VLAN 30, how do I do that?

Thanks.

Ok so now the next question! :)

One of the products we sell involves Live Video Streaming.  In order to test this in house we need to be able to have MultiCast Video pass between VLANs when that video is called for.

Right now if I setup a MultiCast video on say VLAN 40, only systems on that VLAN can see the video.

How would I get a system that is in say VLAN 30 to be able to see that video?

I was reading the documents for the 5448 and it talks about Bridge MultiCast Groups, is this what i need to setup?  I have attempted this, but when I try to put in the MAC address of the Video Server it tells me it is in the wrong format?  Is that the wrong MAC?

Thanks again!

I would look at using the following command to enable multicast routing.

Both the MultiCast Streamer and the PCs receiving the stream are plugged into the PowerConnect 5448.  Does making the change on the 6224 allow MultiCast to go to different VLANs on the 5448?

The 6224 is what is performing the VLAN routing and is what will perform the multicast routing also.

If that continues to not resolve then I would look at the multicast forwarding/bridge on the 54xx. Page 355
