Need help setting up Dell Powerconnect 7048p

mcrman used Ask the Experts™
I am very new to this switch. I need help setting up multiple vlans and the management vlan

I currently have many servers and many clients on the same subnet.

With the switch i want to make a vlan for
iSCSI traffic    12 ports
Servers  12 ports
Clients 12 ports

The seitch management traffic, how do i do this,really ont care what the ip is as this is the only swich on the network but im at a loss as to how to configure everything and still have the clietn traffic get to the servers and managment

I have more than 12 client computers but i also have several unmagaged switches that the clients connect in to.

how do i start, all my attempts have failed.  I was able to run the wizard to set the management ip to and get the web interface but once i start to configure stuff i loose connection.

The step from a flat network to one of multiple VLANs with routing between is a huge step, so take it slowly. First, consider if you really need to do this. It sounds like you have well under 100 client/server devices. If the goal is to increase security, to segregate client devices from servers and control access, then this would be a good reason. If, however, your intent is to increase network speed and efficiency, with that few devices you are likely to see no noticeable improvement. If you wanted multiple client VLANs which could not communicate (for security reasons) with each other but still share resources, that's another reason to do this. But this huge step increases the complexity of your network, which increases the potential things which can go wrong and correspondingly makes troubleshooting more difficult.

OK, but if you want to go through with this, start small:
I assume the network is VLAN 1 (Default VLAN). That is fine. Let's learn to crawl before we walk. For the time being, VLAN 1 should remain untagged on all ports except two that we'll practice VLANs with. Leave port 1 as the server VLAN (untagged VLAN 1), port 2 untagged for the client VLAN, and port 3 untagged the iSCSI VLAN. I assume you are intending to do the routing between VLANs with this switch, you do not have a router set for VLAN routing. You also need to have a DHCP server on each VLAN or configure the switch's "DHCP Relay," but you still need to set up DHCP scopes for each VLAN on whatever server or router you currently use to do DHCP.
The point here is that you only need to mess with the settings on these three ports and three computers plugged into them until you have everything working properly.
What do you think of this so far?


OK, lets Walk.  Lets also simplify this a little further.

2 VLans with no routing between them.

You assume right Vlan1 is for the network, this is where all the servers and clients belong.  Ports 1-24

The ISCSI vlan2 will be used for ISCSI traffic only.   This is  Ports 25-48

I have binded the IP ranges to the vlans.

Is this all i need to do? it does seem to be working.

You mean everything is working accessing iSCSI from the client VLAN?
Do you need 24 ports for iSCSI nodes?


No the ISCSI traffic is segregated from client traffic.   Only my VMware environment will have access to the ISCSI targets,

I had to remove the Bind IP Subnets from the vlans.  

But its working.


Thanks for your help.
