snmp3_real_walk

(PHP 4, PHP 5, PHP 7, PHP 8)

snmp3_real_walk — Return all objects including their respective object ID within the specified one

说明

snmp3_real_walk ( string $hostname , string $security_name , string $security_level , string $auth_protocol , string $auth_passphrase , string $privacy_protocol , string $privacy_passphrase , array|string $object_id , int $timeout = -1 , int $retries = -1 ) : array|bool

The snmp3_real_walk() function is used to traverse over a number of SNMP objects starting from object_id and return not only their values but also their object ids.

参数

hostname

The hostname of the SNMP agent (server).

security_name

the security name, usually some kind of username

security_level

the security level (noAuthNoPriv|authNoPriv|authPriv)

auth_protocol

the authentication protocol (MD5 or SHA)

auth_passphrase

the authentication pass phrase

privacy_protocol

the privacy protocol (DES or AES)

privacy_passphrase

the privacy pass phrase

object_id

The SNMP object id.

timeout

The number of microseconds until the first timeout.

retries

The number of times to retry if timeouts occur.

返回值

Returns an associative array of the SNMP object ids and their values on success or false on error. In case of an error, an E_WARNING message is shown.

范例

Example #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',
  'IF-MIB::ifName.3' => 'STRING: eth2',
  'IF-MIB::ifName.4' => 'STRING: sit0',
  'IF-MIB::ifName.5' => 'STRING: sixxs',
)

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)
                );
            }
}
