Configuring VLAN Trunking

In order to connect multiple VLANs to networks, you need to set up VLAN trunking. The following example illustrates the setup for cognitix Threat Defender assuming that:

  • port enp3s0 is connected to VLAN10 untagged,

  • port enp4s0 is connected to VLAN20 untagged,

  • port enp5s0 is the trunk port for VLAN10 and VLAN20.

Under Network > Manage Processing Interfaces, configure the following setup:

Bridge

Port ID

VLAN Range

VLAN10

enp3s0

VLAN10

enp5s0

10

VLAN20

enp4s0

VLAN20

enp5s0

20

Disable the default interface configuration, i.e. set the slider switch to off. Otherwise, your configuration will not take effect.
