Detailed Description

This module allows managing changes of interface states in AnsaRouter. It can receive XML command from ScenarioManger and accomplish all necessary steps. Now, it supports 2 command: 1. Change of interface state to UP <interfaceup module="R1.interfaceStateManager" int="eth0"> 2. Change of interface state to DOWN <interfacedown module="R1.interfaceStateManager" int="eth0">

    ift = InterfaceTableAccess().get();
    if (ift == NULL){
       throw cRuntimeError("AnsaInterfaceTable not found");
    }
}

void InterfaceStateManager::processCommand ( const cXMLElement & node ) [protected, virtual]

Called by ScenarioManager whenever a script command needs to be carried out by the module.

The command is represented by the XML element or element tree. The command name can be obtained as:

 const char *command = node->getTagName()

Parameters are XML attributes, e.g. a "neighbour" parameter can be retrieved as:

 const char *attr = node->getAttribute("neighbour")

More complex input can be passed in child elements.

See also:: cXMLElement

Implements IScriptable.
