snmp_read_mib()

(PHP 5, PHP 7)

Reads and parses a MIB file into the active MIB tree

说明

snmp_read_mib(string $filename): bool

This 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.

参数

$filename

The filename of the MIB.

范例

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.
