Name	Type	Description
Ieee8021qLayer	compound module	Implements IEEE 802.1Q protocol functionality as a layered architecture with policy and protocol components. The policy submodule handles VLAN filtering and mapping, while the protocol submodule manages tag encapsulation/ decapsulation. Supports both C-VLAN (0x8100) and S-VLAN (0x88A8) tag types through configuration. Enables network segmentation and traffic control in Ethernet networks by processing VLAN tags according to configured policies.
