snmp_read_mib — Reads and parses a MIB file into the active MIB tree
$filename
) : boolThis function is used to load additional, e.g. vendor specific, MIBs so that human readable OIDs like VENDOR-MIB::foo.1 instead of error prone numeric OIDs can be used.
The order in which the MIBs are loaded does matter as the underlying Net-SNMP libary will print warnings if referenced objects cannot be resolved.
filenameThe filename of the MIB.
Example #1 Using snmp_read_mib()
<?php
print_r( snmprealwalk('localhost', 'public', '.1.3.6.1.2.1.2.3.4.5') );
snmp_read_mib('./FOO-BAR-MIB.txt');
print_r( snmprealwalk('localhost', 'public', 'FOO-BAR-MIB::someTable' );
?>
The above example is made up but the results would look like:
Array
(
[iso.3.6.1.2.1.2.3.4.5.0] => Gauge32: 6
)
Array
(
[FOO-BAR-MIB::someTable.0] => Gauge32: 6
)
If you are trying to import mibs with dependencies on other mibs you will have to set the MIBDIRS environment variable.
Unix / Linux: export MIBDIRS=/home/<user>/MIBS:/usr/share/snmp/mibs
Window: Good luck! No really. Try this url out. It has everything that you need to know about setting environment vars in windows.
