Dell N2048P
Hi,
I would appreciate any assistance.
I'm currently learning how to set up VLANs, but things aren't working as expected.
My plan was to create four VLANs:
ports 1-12: VLAN 10
ports 13-24: VLAN 20
ports 25-36: VLAN 30
ports 37-48: VLAN 40
VLAN 10 should be able to communicate with all other VLANs, but the other VLANs shouldn't communicate with each other.
Is it possible to achieve this setup using just one Dell N2048P?
Even with a basic configuration like the one above, I couldn't get devices in one VLAN to ping devices in another.
ip routing
interface vlan 1 1
ip address 192.168.0.250 255.255.255.0
exit
interface vlan 10 2
ip address 192.168.4.1 255.255.255.0
exit
interface vlan 20 3
ip address 192.168.5.1 255.255.255.0
exit
interface vlan 30 3
ip address 172.16.0.1 255.255.252.0
exit
interface vlan 40 4
ip address 172.16.4.1 255.255.252.0
exit
ip default-gateway 192.168.0.1

Hello,
You're basically trying to split your network into smaller, more manageable chunks — that's what VLANs (Virtual LANs) are for. They help with traffic control, security, and keeping things organized.
By default, all ports on Dell N-series switches (like N1100, N2000, N3000, etc.) are in VLAN 1, which means they’re all part of the same big network and can talk to each other without any restrictions. If you don’t change anything, all traffic is untagged and stays in that one big group.
🔧 Creating a VLAN (Basic Example)
To create a VLAN, you just go into config mode and type:
That creates VLAN 10. You can do the same for other VLANs — valid IDs are from 1 to 4093.
🧑💻 Creating Multiple VLANs at Once
You can also create several VLANs in one go:
That makes VLANs 3, 4, and 5.
🏷️ Naming a VLAN (Optional)
You can give your VLAN a name to make it easier to remember:
Now VLAN 10 is called "Storage". VLAN 1 is always called "default" and you can’t rename it.
🔍 Checking VLANs
