    范例

    Example #1 Using snmp2_real_walk()

    <?php
     print_r(snmp2_real_walk("localhost", "public", "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
        )
    

    参见

    Remember that the timeout includes trip time for transport, so setting it too low and sending it across the country will time out and return a 'No response from x.x.x.x'
