snmp3_set — Set the value of an SNMP object
$hostname,$security_name,$security_level,$auth_protocol,$auth_passphrase,$privacy_protocol,$privacy_passphrase,$object_id,$type,$value,$timeout = -1,$retries = -1
snmp3_set() is used to set the value of an SNMP object
specified by the object_id.
Even if the security level does not use an auth or priv protocol/password valid values have to be specified.
hostnameThe hostname of the SNMP agent (server).
security_namethe security name, usually some kind of username
security_levelthe security level (noAuthNoPriv|authNoPriv|authPriv)
auth_protocolthe authentication protocol (MD5 or SHA)
auth_passphrasethe authentication pass phrase
privacy_protocolthe privacy protocol (DES or AES)
privacy_passphrasethe privacy pass phrase
object_idThe SNMP object id.
typeMIB 定義了各個對象 id 的類型。必須是下面列出的單個字符之一。
| = | MIB類型 |
| i | INTEGER |
| u | INTEGER |
| s | STRING |
| x | HEX STRING |
| d | DECIMAL STRING |
| n | NULLOBJ |
| o | OBJID |
| t | TIMETICKS |
| a | IPADDRESS |
| b | BITS |
如果在編譯 SNMP 庫時定義了 OPAQUE_SPECIAL_TYPES,那么下列值是合法的:
| U | unsigned int64 |
| I | signed int64 |
| F | float |
| D | double |
這些值大都會使用與 ASN.1 相符的類型。's','x','d' 以及 'b' 都是指定一個八字節(jié)字符串值的方式。并且 'u' 無符號類型也可用于處理 Gauge32 值。
如果 MIB 文件是用 "snmp_read_mib" 或者通過在 libsnmp config 中指定而加載入 MIB 樹時,
'=' 可以被用作為所有對象的 type 參數(shù),因為 type 可以被自動從 MIB 中讀取。
注意有兩種方式可以設(shè)定 BITS 類型的變量,例如 "SYNTAX BITS {telnet(0), ftp(1), http(2), icmp(3), snmp(4), ssh(5), https(6)}":
更多細節(jié)見范例部分。
valueThe new value
timeoutThe number of microseconds until the first timeout.
retriesThe number of times to retry if timeouts occur.
成功時返回 true, 或者在失敗時返回 false。
If the SNMP host rejects the data type, an E_WARNING message like "Warning: Error in packet. Reason: (badValue) The value given has the wrong type or length." is shown. If an unknown or invalid OID is specified the warning probably reads "Could not add variable".
示例 #1 Using snmp3_set()
<?php
snmp3_set('localhost', 'james', 'authPriv', 'SHA', 'secret007', 'AES', 'secret007', 'IF-MIB::ifAlias.3', 's', "foo");
?>
示例 #2 Using snmp3_set() for setting BITS SNMP object id
<?php
snmp3_set('localhost', 'james', 'authPriv', 'SHA', 'secret007', 'AES', 'secret007', 'FOO-MIB::bar.42', 'b', '0 1 2 3 4');
// or
snmp3_set('localhost', 'james', 'authPriv', 'SHA', 'secret007', 'AES', 'secret007', 'FOO-MIB::bar.42', 'x', 'F0');
?>
