#21992 [Com]: snmpget returns wrong value on negative integer

ID: 21992 Comment by: spoon@nexdot.net Reported By: spoon@nexdot.net Status: Open Bug Type: SNMP related Operating System: Windows XP Pro SP1 PHP Version: 4CVS-2003-01-31 (stable) New Comment: Any update on this? If it needs more information/some way of confirmation, i would be happy to aid. Previous Comments: ------------------------------------------------------------------------ [2003-01-31 21:31:25] spoon@nexdot.net I believe i read somewhere that PHP's integer max was 2147483647? If using snmp to pull bandwidth information from a device (such as ifInOctets and ifOutOctets), the number DOES constandly rise. If using a device with snmpv1 (32bit) the counter will only reach a certain number before it rolls over the the opposite and negative number and counts toward the maximum again. The Max (and prolly min?) is the same as PHP's. "INTEGER(-2147483648..2147483647) -- corresponds to a signed 32-bit int" Well, once the counter turns over to the negative, php only returns "2147483647" for every negative value it reads. Such as, my ifInOctets for my cisco router is now reading '-1980181848', and php's snmpget on that oid returns '2147483647', but when the counter is positive, it returns the correct value. (this is probably a problem on 64bit snmpv2 since i believe its maximum is much higher, but thats probably not fix-able) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21992&edit=1
