Issue/Introduction

• How do I use ASL to search and list a Class of devices in a Smarts IP domain for a particular property?

• How to search an IP domain for devices containing a particular property such as the same system OID (Object Identifier) in different devices

Environment

All supported releases of Smart

Resolution

A relatively simple ASL script can be used to search for properties within a Class, such as searching IP domain devices for the same system OID (Object Identifier) in a particular Class. The following example ASL script could be used to search for the "SystemObjectID" within the "Switch" Class:

START {}

do {

print("starting to process instances");

DeviceList = getInstances("Switch");  /*add the Instance type here, e.g., Switch, Router, Host*/

foreach aDevice (DeviceList) {

/*print(aDevice." checked");  Uncomment to list all devices checked*/

instanceObj = object(aDevice);

if (instanceObj->SystemObjectID == ".1.3.6.1.4.1.9.1.501") { /* add the SystemObjectID here */

print(aDevice." has a SystemObjectID of .1.3.6.1.4.1.9.1.501");

}

}

stop();

This script can be run using BASEDIR/IP/smarts/bin/sm_adapter -s [IP Domain Name] scriptname.asl
