simple module

This module updates the VlanReq tag on packets.

Inheritance diagram

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

Extends

Name	Type	Description
PacketFlowBase	simple module	This is a base module for various packet flow modules. A packet flow module passes or streams all pushed or pulled packets after processing them from its input to its output.

Parameters

Name	Type	Default value	Description
displayStringTextFormat	string	"processed %p pk (%l)"	determines the text that is written on top of the submodule
interfaceTableModule	string
mappedVlanIds	object	{}	maps network interface name to another map which maps accepted VLAN ids to replacement VLAN ids, '*' as interface name matches all interfaces, -1 VLAN id matches if no tag is present

Properties

Name	Value	Description
display	i=block/switch
class	VlanReqMapper
