README

PHP library providing a single, vendor-agnostic interface for network equipment: switches, OLTs, and routers.

Overview

Switcher-Core abstracts away vendor-specific protocols and command sets behind one API. Instead of writing a wrapper for every vendor, you call a named module (e.g. system, fdb, vlans) against a Device, and the library:

Detects the device model from SNMP sysDescr / sysObjectID (or an explicit model key).
Loads the matching YAML configuration (OIDs, module bindings) for that model.
Dispatches the call to the vendor-specific module implementation, or a shared/general one when no vendor-specific implementation exists.

The set of modules supported by a given device, and the exact shape of the response, depend on the device's capabilities and vendor. This is a deliberate trade-off: a single strict schema across all vendors is not achievable for heterogeneous network hardware. See the field naming convention below for how the library keeps responses as consistent as practical.

If your equipment is not in the supported list, implement the module classes and configuration described in Module Development and contribute it, or maintain it in a fork.

Installation

composer require meklis/switcher-core

Quick start

<?php
require __DIR__ . "/vendor/autoload.php";

use SwitcherCore\Modules\Helper;
use SwitcherCore\Switcher\CoreConnector;
use SwitcherCore\Switcher\Device;
use SwitcherCore\Switcher\PhpCache;

$deviceIp = '127.0.0.1';
$deviceCommunity = 'public';
$deviceLogin = 'login';
$devicePassword = 'password';

$coreConnector = new CoreConnector(
    // Path to the library's built-in configuration directory.
    // Copy configs/ out of vendor/meklis/switcher-core if you need to customize it.
    Helper::getBuildInConfig()
);

$connector = ($coreConnector)
    // Optional, but recommended. Use a shared cache (e.g. Memcached) in production.
    ->setCache(new PhpCache());

$core = $connector->init(
    // init() detects the model and returns a ready-to-use Device instance.
    Device::init($deviceIp, $deviceCommunity, $deviceLogin, $devicePassword)
        // Connection parameters, shown here with their defaults.
        ->set('consoleConnectionType', Device::CONSOLE_TELNET)
        ->set('consoleTimeout', 10)
        ->set('consolePort', 23)
        ->set('snmpRepeats', 3)
        ->set('snmpTimeoutSec', 2)
        ->set('mikrotikApiPort', 8728)
);

echo json_encode($core->action('system'), JSON_PRETTY_PRINT);

Example output of the system module (exact fields vary by vendor):

{
    "descr": "RouterOS RB952Ui-5ac2nD",
    "uptime": "8d 9h 55min 32sec",
    "contact": "",
    "name": "G_OfficeMik",
    "location": "",
    "meta": {
        "name": "Mikrotik RB952Ui-5ac2nD",
        "detect": {
            "description": "^RouterOS RB952Ui-5ac2nD$",
            "objid": "^.1.3.6.1.4.1.14988.1$"
        },
        "ports": 0,
        "extra": [],
        "modules": [
            "system",
            "arp_info",
            "arp_ping",
            "interface_vlan_info",
            "dhcp_server_info",
            "lease_info",
            "ctrl_static_arp",
            "ctrl_static_lease"
        ]
    }
}

Response field convention

Some modules (e.g. fdb, pon_onts_status) are implemented differently across vendors and platforms, so their output cannot be perfectly uniform. The library follows one rule consistently:

A field with no leading underscore is part of the module's common contract: same name, same meaning, across every implementation of that module.
A field prefixed with _ is platform- or vendor-specific and not part of the common contract.
When two platforms report semantically the same value under different names, the common field uses a neutral name, and each vendor's original field name is kept alongside it with a leading underscore (e.g. a common ident field, plus _serial on one platform and _mac on another).

Interface objects (interface / interfaces) follow their own, already-established convention: id, name, type, parent are common; _port, _slot, _onu, _snmp_id, _technology, _type, etc. are platform-specific.

See Module Development for details and examples.

Repository layout

Path	Purpose
`src/Switcher/`	Core, connectors, `Device`, console wrappers, cache.
`src/Config/`	YAML readers and collectors for models, OIDs, modules, traps.
`src/Modules/`	Module implementations, one namespace per vendor/platform.
`configs/modules.yml`	Registry of all modules and their arguments.
`configs/models/`	Device model definitions: detection rules and module bindings.
`configs/oids/`	SNMP OID databases, grouped by vendor/platform.
`configs/traps/`	SNMP trap configuration.
`docs/`	Generated device/module documentation and examples.
`src/Dev/`, `bin/console`	Local development console for calling modules and inspecting support.
`tests/`	Automated tests. Coverage is currently limited to config consistency checks, not real-device behavior.

Developing and extending modules

Adding support for a new device model, or a new module, is a configuration-plus-code task: OID files, a model definition, and (when no existing module fits) a PHP class. This is documented in full in Module Development.

Testing

composer tests

This runs the PHPUnit suite (tests/), which currently checks configuration consistency (OIDs, models, modules). It does not verify behavior against real hardware — automated tests here are not a substitute for testing against an actual device. See Module Development for how to do that with bin/console.
