VlanReqFilter
simple moduleThis 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 |
