说明

snmp3_real_walk(
    string $hostname,

    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|false

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 authentication protocol ("MD5", "SHA", "SHA256", or "SHA512")
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.

更新日志

版本	说明
8.1.0	The `auth_protocol` now accepts `"SHA256"` and `"SHA512"` when supported by libnetsnmp.

示例

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',
  '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)
                );
            }
}
