the authentication protocol (MD5 or SHA)
-
auth_passphrase -
the authentication pass phrase
-
privacy_protocol -

-
object_id -
The SNMP object id.
-
timeout -

Examples
Example #1 Using snmp3_real_walk()
<?php
var_export(snmp3_real_walk('localhost', 'james', 'authPriv', 'SHA', 'secret007', 'AES', 'secret007', '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', )
