范例

示例 #1 Using snmp3_real_walk()

<?php
 var_export
(snmp3_real_walk('localhost''james''authPriv''SHA''secret007''AES''secret007''IF-MIB::ifName'));
?>

The above will output something like:

array (
  'IF-MIB::ifName.1' => 'STRING: lo',
  'IF-MIB::ifName.2' => 'STRING: eth0',

Use this function for debug snmp-connection.

<?php
error_reporting
(8191);
date_default_timezone_set('Europe/Moscow');
ini_set('display_errors',1);

snmp_test_connection('12.34.56.78', 'guest', 'guest')

function
snmp_test_connection($ip, $user, $pass){
   
$a = array('noAuthNoPriv','authNoPriv','authPriv');
   
$b = array('MD5','SHA');
   
$c = array('DES','AES');

   
$branch    = '.1.3.6.1.2.1.1.3'; // upTime

   
foreach($a as $aPriv)
        foreach(
$b as $bProt)
            foreach(
$c as $cPrivProt){
                echo
'time = '.date('Y-m-d H:i:s').'<br/>';
                echo
'<b>sec_level=</b>'.$aPriv.'<br/><b>auth_protocol=</b>'.$bProt.'<br/><b>priv_protocol=</b>'.$cPrivProt.'<br/>Request = ';
               
var_dump(
                   
snmp3_real_walk($ip, $user, $aPriv, $bProt, $pass, $cPrivProt, $pass, $branch)
                );
            }
}

?>
