        string $security_level,
        string $auth_protocol,

        string $privacy_passphrase,
        array|string $object_id,
        int $timeout = -1,

    snmp3_walk() function is used to read all the values from an SNMP agent specified by the hostname.

    Even if the security level does not use an auth or priv protocol/password valid values have to be specified.

    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", "SHA", "SHA256", or "SHA512")
    auth_passphrase
    the authentication pass phrase
    privacy_protocol
    the privacy protocol (DES or AES)
    privacy_passphrase
    the privacy pass phrase
    object_id
    If null, object_id is taken as the root of the SNMP objects tree and all objects under that tree are returned as an array. If object_id is specified, all the SNMP objects below that object_id are returned.
    timeout
    The number of microseconds until the first timeout.
    retries
    The number of times to retry if timeouts occur.

    示例

    示例 #1 snmp3_walk() Example

    <?php
    $ret     = snmp3_walk('localhost', 'james', 'authPriv', 'SHA', 'secret007', 'AES', 'secret007', 'IF-MIB::ifName');
    var_export($ret);
    ?>

    Above function call would return all the SNMP objects from the SNMP agent running on localhost: 

    array (
  0 => 'STRING: lo',
  1 => 'STRING: eth0',
  2 => 'STRING: eth2',
  3 => 'STRING: sit0',
  4 => 'STRING: sixxs',
)
