OSS_SNMP - A PHP SNMP library for people who hate SNMP MIBs and OIDs!
Copyright (c) 2012, Open Source Solutions Limited, Dublin, Ireland
All rights reserved.

See: https://github.com/opensolutions/OSS_SNMP/

This is an example script to show how to use OSS_SNMP. It requires two or three arguments:

 - the IP address of hostname of a SNMP capable host
 - the SNMP v2 community string for that host
 - the index of the interface to show details for

If the third argument is missing, it will print interface indexes and names.

For example:

    {$argv[0]} 192.168.10.20 public


HELPTEXT;

    exit( 1 );
}

require_once( dirname( __FILE__ ) . '/../OSS_SNMP/SNMP.php' );

$host = new \OSS_SNMP\SNMP( $argv[1], $argv[2] );

if( count( $argv ) == 3 )
{
    echo "\nNumber of interfaces on {$argv[1]}: " . $host->useIface()->numberofInterfaces() . "\n\n";

    echo "ID:  Name  - Descrition - Type - Admin/Operational State\n\n";

    foreach( $host->useIface()->names() as $id => $name )
    {
        echo "{$id}: {$name} - {$host->useIface()->descriptions()[$id]} - {$host->useIface()->types(1)[$id]}"
            . " - {$host->useIface()->adminStates(1)[$id]}/{$host->useIface()->operationStates(1)[$id]}\n";
    }

    echo "\n";
    exit( 0 );
}

$names = $host->useIface()->names();
$id = $argv[3];

if( !isset( $names[ $id ] ) )
{
    echo "Unknown interface index!\n";
    exit( 2 );
