ID: 54502 Updated by: lytbo...@php.net Reported by: c...@php.net Summary: Add support for the "BITS" datatype -Status: Assigned +Status: Feedback Type: Feature/Change Request Package: SNMP related PHP Version: trunk-SVN-2011-04-10 (SVN) Assigned To: lytboris Block user comment: N Private report: N New Comment: Please try using this snapshot: http://snaps.php.net/php5.4-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Now you can combine SNMP_VALUE_OBJECT with one of SNMP_VALUE_PLAIN or SNMP_VALUE_LIBRARY to alter 'value' output mode. As for >The value is not even numerical, it has to be converted to 0x80 using >bin2hex()! This is normal, because this is exactly what php-snmp receives from remote SNMP agent. Previous Comments: ------------------------------------------------------------------------ [2011-07-17 13:18:27] lytbo...@php.net Automatic comment from SVN on behalf of lytboris Revision: http://svn.php.net/viewvc/?view=revision&revision=313331 Log: fix FR #54502: allow user to change OID value output mode when SNMP_VALUE_OBJECT is used. ------------------------------------------------------------------------ [2011-07-17 09:18:04] lytbo...@php.net There is support for BITS datatype actually when SNMP_VALUE_LIBRARY is enabled for value processing. When you enable other SNMP_VALUE_* modes no value processing is performed and output from remote SNMP agent is passed through SNMP library. ------------------------------------------------------------------------ [2011-04-10 15:34:01] c...@php.net Description: ------------ The SNMP command line tools are able to translate the numeric return values for OIDs of the "BITS" datatype back to meaningful string values by parsing the relevant parts of the MIB. The PHP functions currently seem unable to do that. I.e. in the following example I would like to get the string "notification" or "set" as return value but only get "0" or "1". As there is no other method to find and parse the MIB I'm left with hardcoding the values in the PHP script: $ snmptranslate -Td DISMAN-EVENT-MIB::mteEventActions DISMAN-EVENT-MIB::mteEventActions mteEventActions OBJECT-TYPE -- FROM DISMAN-EVENT-MIB SYNTAX BITS {notification(0), set(1)} Test script: --------------- >From commandline (mind the strange quotes, they're neccessary!): $ snmpwalk -v2c -c private localhost "DISMAN-EVENT-MIB::mteEventActions.\"_snmpd\".'_linkDown'" DISMAN-EVENT-MIB::mteEventActions."_snmpd".'_linkDown' = BITS: 80 notification(0) With PHP: snmp_set_valueretrieval(SNMP_VALUE_OBJECT); $snmp = new SNMP(SNMP_VERSION_2C, 'localhost', 'private'); $x = $snmp->get("DISMAN-EVENT-MIB::mteEventActions.\"_snmpd\".'_linkDown'"); var_dump($x); var_dump(bin2hex($x->value)); I get: object(stdClass)#190 (2) { ["type"]=> int(4) ["value"]=> string(1) "�" } string(2) "80" The value is not even numerical, it has to be converted to 0x80 using bin2hex()! Expected result: ---------------- Maybe * the SNMP_VALUE_OBJECT representation object can be enhanced to include alternative representations: object(stdClass)#190 (2) { ["type"]=> int(4) ["value"]=> string(1) "�" ["bits_value"]=> string(15) "notification(0)" } * or the the snmp_set_enum_print() function is used to toggle BITS, too * or a snmp_set_bits_print() function is introduced * or a snmp_translate() function is introduced that returns the "snmptranslate" output as PHP data structure ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=54502&edit=1
