Switch Setup issues

Switches

Hello,

I’m experiencing a complete loss of connectivity on my network after configuring my Alta Labs switch, and I’m getting an APIPA warning in the controller.

Setup:

  • Alta Labs Switch connected to:

    • Firewalla Gold router (uplink port)

    • Alta Labs AP6 Pro access point

  • Both ports configured with:

    • Native VLAN: Default

    • Allowed VLANs: Default and tried All (all VLANs allowed)

    • Mode: Standard

Problem: After configuration, I’m receiving this error in the controller: “Note: APIPA (self-assigned) IPs detected. This is typically caused by a DHCP pool that is too small, or misconfigured static IPs, and will cause intermittent connectivity.”

All network connectivity has been lost. Devices are receiving self-assigned 169.254.x.x addresses instead of proper DHCP addresses from my Firewalla router.

Questions:

  1. What does “Default” actually mean for the Native VLAN setting? Is it VLAN 1, or something else in Alta’s system?

  2. Should I explicitly set the Native VLAN to a specific VLAN ID instead of leaving it as “Default”? (I tied it with one VLAN ID and it works fine as an access port.

  3. Are there any other switch configuration settings I should check to ensure proper DHCP communication between the Firewalla router and connected devices?

My DHCP pool on the Firewalla is properly configured and was working fine before adding the Alta switch. Any guidance would be greatly appreciated!

Thanks in advance.

I see your support ticket, but I think I’ll mostly address the questions here for public sake. Happy to take anything with more specific info to private though if preferred.

  1. Native untagged is 1. VID 1 === untagged too, fwiw.
  2. That depends on your goal.
  3. Disable DHCP guarding, or set it to manual and define the MAC of your Firewalla. That should address your DHCP sisues. Settings>System>Advanced>DHCP Guard. The auto setting is only meant for Route10, otherwise it will not work.

Thank you for the quick response. I see that the DHCP guard is disabled. I figured out the issue, I did not create the new VLANS in the switch, I assumed the vlans from the AP will be sent over here automatically. User Error on my end.
Thanks Again for explaining me the things!
