SNMP::set — Set the value of an SNMP object
Requests remote SNMP agent setting the value of
one or more SNMP objects specified by the objectId.
If objectId is string, both
type and value must be
string too. If objectId is array
value must be equal-sized array containing
corresponding values, type may be either
string (it's value will be used for all
objectId-value pairs) or
equal-sized array with per-OID value. When any other parameters' combinations are
used, a number of E_WARNING messages may be shown with detailed description.
objectIdtype| = | MIB类型 |
| i | INTEGER |
| u | INTEGER |
| s | STRING |
| x | HEX STRING |
| d | DECIMAL STRING |
| n | NULLOBJ |
| o | OBJID |
| t | TIMETICKS |
| a | IPADDRESS |
| b | BITS |
OPAQUE_SPECIAL_TYPES,那么下列值是合法的:
| U | unsigned int64 |
| I | signed int64 |
| F | float |
| D | double |
type 参数,因为 type 可以被自动从 MIB 中读取。
注意有两种方式可以设定 BITS 类型的变量,例如
"SYNTAX BITS {telnet(0), ftp(1), http(2), icmp(3), snmp(4), ssh(5), https(6)}":
value
本方法默认不抛出任何异常。如果要在某些库出错时抛出 SNMPException
异常,用户需要将 SNMP 类参数 exceptions_enabled
设定为相应的值。更多细节见 SNMP::$exceptions_enabled
的解释。
示例 #1 Set single SNMP object id
<?php
$session = new SNMP(SNMP::VERSION_2C, "127.0.0.1", "private");
$session->set('SNMPv2-MIB::sysContact.0', 's', "Nobody");
?>示例 #2 Set multiple values using single SNMP::set() call
<?php
$session = new SNMP(SNMP::VERSION_2C, "127.0.0.1", "private");
$session->set(array('SNMPv2-MIB::sysContact.0', 'SNMPv2-MIB::sysLocation.0'), array('s', 's'), array("Nobody", "Nowhere"));
// or
$session->set(array('SNMPv2-MIB::sysContact.0', 'SNMPv2-MIB::sysLocation.0'), 's', array("Nobody", "Nowhere"));
?>示例 #3 Using SNMP::set() for setting BITS SNMP object id
<?php
$session = new SNMP(SNMP::VERSION_2C, "127.0.0.1", "private");
$session->set('FOO-MIB::bar.42', 'b', '0 1 2 3 4');
// or
$session->set('FOO-MIB::bar.42', 'x', 'F0');
?>
