VlanReqFilter

Package: inet.linklayer.vlan

VlanReqFilter

simple module

This module filters out packets based on the attached VlanReq tag.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Extends

Name Type Description
PacketFilterBase simple module

This is a base module for various packet filter modules. Derived modules must implement a single packet matcher function which determines if a packet is to be passed through or filtered out.

Parameters

Name Type Default value Description
displayStringTextFormat string "dropped %d/%p pk (%k/%l)"

determines the text that is written on top of the submodule

backpressure bool false
interfaceTableModule string
acceptedVlanIds object {}

maps network interface name to a list of accepted VLAN ids, '*' as interface name matches all interfaces, -1 VLAN id matches if no tag is present
