Knowledge Base Use your Omada Switch as Layer 3 Switch (intervlan routing)
Hello,
Happy new year to everyone. For those interested to use their Omada switch to facilitate intervlan routing rather than their Gateway, you can do the following:
Edit update note:
-
You will still need an Internet Gateway, it will not replace your Gateway
-
Layer 3 Switch can't do VPN server/client or any of the fancy WAN features (i.e. port forward) as well as LAN features (i.e. no mDNS).
-
Not tested on many switches. Check your specs and clients.
Steps:
1. Get your Omada Switch's IP Address
Devices > IP Addresss
2. Create a Layer 2-Broadcast-only VLAN
Settings > Wired Networks > LAN > Create New LAN
Name: <Enter value>
Purpose: VLAN
VLAN ID: <Enter value>
Application: Switches Only
"Save"!
3. Configure Switch VLAN Interface
Devices > [Switch] > Config > VLAN Interface > Enable > Edit
IP Address Mode: Static
IP Address: <Enter value>
Subnet Mask: <Enter value>
DHCP Mode: DHCP Server
DHCP Range: <Enter range>
Primary DNS: <Enter value>
Secondary DNS: <Enter value>
Default Gateway: <Enter value>
"Apply"
"Apply" again!
4. Allow traffic to Gateway
Settings > Transmission > Routing > Static Route > Create New Route
Name: <Enter value>
Status: Enable
Destination IP/Subnet: <Enter values created in Step 3>
Route Type: Next Hop
Next Hop: <Enter value from Step 1>
"Create"
Testing:
- Configure switch port with the VLAN profile defined as Gateway Interface. Plug device and ping any IP created from Step 3
- Configure a switch port with the VLAN profile created from Step 2. Plug device, device should have IP address coming from range defined from Step 3
- Configure a switch port with the VLAN profile created from Step 2. Plug device and browse the net
If you want to see this in action or prefer a video guide, I have a video posted in YT, configuration starts at 13:57. This is an experimental design, not recommended for production.
