snmp3_set - Set the value of an SNMP object

SYNOPSIS

       bool  snmp3_set (string	$host, string  $sec_name, string  $sec_level, string  $auth_protocol, string  $auth_passphrase, string	$priv_pro-
       tocol, string  $priv_passphrase, string	$object_id, string  $type, string  $value, [int  $timeout = 1000000], [int  $retries = 5])

DESCRIPTION

       snmp3_set(3) 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.

PARAMETERS

	      o $host
		- The hostname of the SNMP agent (server).

	      o $sec_name
		- the security name, usually some kind of username

	      o $sec_level
		- the security level (noAuthNoPriv|authNoPriv|authPriv)

	      o $auth_protocol
		- the authentication protocol (MD5 or SHA)

	      o $auth_passphrase
		- the authentication pass phrase

	      o $priv_protocol
		- the privacy protocol (DES or AES)

	      o $priv_passphrase
		- the privacy pass phrase

	      o $object_id
		- The SNMP object id.

	      o $type
		- The MIB defines the type of each object id. It has to be specified as a single character from the below list.

	       If OPAQUE_SPECIAL_TYPES was defined while compiling the SNMP library, the following are also valid:

	      types

	      +--+----------------+
	      |U |		  |
	      |  |		  |
	      |  | unsigned int64 |
	      |  |		  |
	      |I |		  |
	      |  |		  |
	      |  |  signed int64  |

	      |  |     double	  |
	      |  |		  |
	      +--+----------------+
	       Most of these will use the obvious corresponding ASN.1 type. 's', 'x', 'd' and 'b' are all different ways of  specifying  an  OCTET
	      STRING  value, and the 'u' unsigned type is also used for handling Gauge32 values.  If the MIB-Files are loaded by into the MIB Tree
	      with "snmp_read_mib" or by specifying it in the libsnmp config, '=' may be used as the $type parameter for all  object  ids  as  the
	      type can then be automatically read from the MIB.  Note that there are two ways to set a variable of the type BITS like e.g. "SYNTAX
	      BITS {telnet(0), ftp(1), http(2), icmp(3), snmp(4), ssh(5), https(6)}":

		     o Using type "b" and a list of bit numbers. This method is not recommended since GET query for the same OID would return e.g.
		     0xF8.

		     o Using type "x" and a hex number but without(!) the usual "0x" prefix.

	       See examples section for more details.

	      o $value
		- The new value

	      o $timeout
		- The number of microseconds until the first timeout.

	      o $retries
		- The number of times to retry if timeouts occur.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

	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".

EXAMPLES

       Example #1

	      Using snmp3_set(3)

	      <?php
		snmp3_set('localhost', 'james', 'authPriv', 'SHA', 'secret007', 'AES', 'secret007', 'IF-MIB::ifAlias.3', 's', "foo");
	      ?>

       Example #2

	      Using snmp3_set(3) 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');
	      ?>
