Why do I always see the traffic from management VLAN when the PC connects to a Nebula Switch port?

There is a mechanism on Nebula Switch(cloud mode) that prevents the Switch from going offline when changing Uplink ports, and the management VLAN is fixed to all switch ports by default.

To do so, you need to access Configure > Switches > Switch ports on NCC in order to check if the Switch ports are assigned to management VLAN.

Select Management control to "Disabled" so that your switch will not add this port as a management VLAN member.

  • Configure PVID with another VLAN that is not the management VLAN, and do not have to include management VLAN in Allowed VLANs.
  • Default PVID is 1 and Allow VLANs is "All".
