Bug description:Add support for the "BITS" datatype
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
