========================================================================================================================================

[](#freedsx-snmp-)

FreeDSx SNMP is a pure PHP SNMP library. It has no requirement on the core PHP SNMP extension. It implements SNMP client functionality described in [RFC 3412](https://tools.ietf.org/html/rfc3412) / [RFC 3416](https://tools.ietf.org/html/rfc3416) / [RFC 3414](https://tools.ietf.org/html/rfc3414). It also includes functionality described in various other RFCs, such as SHA2 authentication ([RFC 7860](https://tools.ietf.org/html/rfc7860)) and strong encryption mechanisms ([3DES](https://tools.ietf.org/html/draft-reeder-snmpv3-usm-3desede-00) / [AES-192-256](https://tools.ietf.org/html/draft-blumenthal-aes-usm-04)). Some main features include:

- SNMP version 1, 2, and 3 support.
- Supports all authentication mechanisms (md5, sha1, sha224, sha256, sha384, sha512).
- Supports all privacy encryption mechanisms (des, 3des, aes128, aes192, aes256).
- Supports all client request types (Get, GetNext, GetBulk, Set, Inform, TrapV1, TrapV2).
- Supports sending SNMPv1 and SNMPv2 traps (including inform requests).
- Trap Sink server for receiving and processing incoming traps.

The OpenSSL extension is required for privacy / encryption support. The GMP extension is required for 64-bit counters (BigCounter).

Getting Started
===============

[](#getting-started)

Install via composer:

```
composer require freedsx/snmp
```

Use the SnmpClient class and the helper classes:

```
use FreeDSx\Snmp\SnmpClient;

$snmp = new SnmpClient([
    'host' => 'servername',
    'version' => 2,
    'community' => 'secret',
]);

# Get a specific OID value as a string...
echo $snmp->getValue('1.3.6.1.2.1').PHP_EOL;

# Get a specific OID as an object...
$oid = $snmp->getOid('1.3.6.1.2.1');
var_dump($oid);

echo sprintf("%s == %s", $oid->getOid(), (string) $oid->getValue()).PHP_EOL;

# Get multiple OIDs and iterate through them as needed...
$oids = $snmp->get('1.3.6.1.2.1.1.1', '1.3.6.1.2.1.1.3', '1.3.6.1.2.1.1.5');

foreach($oids as $oid) {
    echo sprintf("%s == %s", $oid->getOid(), (string) $oid->getValue()).PHP_EOL;
}

# Using the SnmpClient, get the helper class for an SNMP walk...
$walk = $snmp->walk();

# Keep the walk going until there are no more OIDs left
while($walk->hasOids()) {
    try {
        # Get the next OID in the walk
        $oid = $walk->next();
        echo sprintf("%s = %s", $oid->getOid(), $oid->getValue()).PHP_EOL;
    } catch (\Exception $e) {
        # If we had an issue, display it here (network timeout, etc)
        echo "Unable to retrieve OID. ".$e->getMessage().PHP_EOL;
    }
}

echo sprintf("Walked a total of %s OIDs.", $walk->count()).PHP_EOL;
```

For a complete configuration reference please see the [configuration doc](/docs/Client/Configuration.md). There are also SNMP v3 examples for [NoAuthNoPriv](/docs/Client/General-Usage.md#noauthnopriv), [AuthNoPriv](/docs/Client/General-Usage.md#authnopriv), and [AuthPriv](/docs/Client/General-Usage.md#authpriv)in the [general usage doc](/docs/Client/General-Usage.md).
