Packet loss on TL-SG2428P after enabling VLAN profile on ports

Model: TL-SG2428P  
Hardware Version: V1
Firmware Version: 5.20.2 Build 20240115 Rel.72847

Router: Proxmox with OPNsense virtualized
Switch: SG2428P

Situation: After configuring a VLAN interface and then enabling that VLAN interface on the above switch, I can see and experience frequent packet loss across my entire network (not just the VLAN that was enabled)

Details:

  • Proxmox host has an intel 4x 1GB NIC, one to WAN, one to LAN (switch port).

  • Personal Laptop configured on switch port 12 (example)

  • OPNsense Router virtualized on Proxmox. LAN gateway is 10.0.0.1

  • OPNsense Router has VLAN Gateway configured as 10.0.201.1/24, DHCP range of 10.0.201.20-10.0.201.254

  • OPNsense VLAN 201 is configured as 10.0.201.1/24, VLAN 201. DHCP server disabled, Legal DHCP server 10.0.0.1, DHCP L2 relay enabled.

  • On Switch > Config > Configure VLAN 201 - static IP 10.0.201.2, mask 255.255.255.0, DHCP Relay 10.0.0.1. Apply.

  • On Switch > Config > VLAN Interface - Enable VLAN 201.

  • On Switch > Ports > Port 12 - Profile VLAN 201. Apply.

Once I assign a port to the VLAN I can start to see that pings and network connectivity drop frequently. Easily for 1-2 seconds every 30 seconds. This is observed across desktops, laptops, and Wi-Fi devices as well.

If I do not have a VLAN profile assigned to a port (other than using "All") then I do not experience this packet loss at all.

Is this a misconfiguration that I have made on the switch, OPNsense, or a hardware issue with the switch?

Hi @WholesomeTRex 

Thanks for posting in our business forum.

As this involved a third-party product, we are not sure if there is a problem between ours and theirs.

To identify if this is a hardware issue, connect two computers and set them with static IPs, the switch is not connected to any other devices but them, run ping to test if there is a hardware issue with it.

 

About the profile, if you use all and it works okay, that could be a problem with your VLAN config issue. Refer to the guide on how to set VLAN on a switch on forum.
