Add support for Huawei CE6870-48S6CQ-EI VRP 8.191 #79

Closed AlexKr23 closed 1 month ago

Please add discovery for Huawei CE6870-48S6CQ-EI VRP 8.191

I've modified /srv/ixpmanager/vendor/opensolutions/oss-snmp/src/OSS_SNMP/Platforms/vendor_huawei.php

With this:

// 'CE6870-48S6CQ-EI Huawei Versatile Routing Platform Software VRP (R) software, Version 8.191 (CE6870EI V200R019C10SPC800) Copyright (C) 2012-2020 Huawei Technologies Co., Ltd.'
// .1.3.6.1.2.1.1.2.0 = OID: .1.3.6.1.4.1.2011.2.239.32
// https://www.phpliveregex.com/p/LRg
else if( preg_match( '/^Huaw.* Version ([0-9\.]+)\ \((\D{2}\d{4}\D{2}).*HUAWEI\ (CE\d+\-\w+\-EI)$/',
                $sysDescr, $matches ) ) {

    $this->setVendor( 'Huawei' );
    $this->setModel( $matches[3] );
    $this->setOs( 'Huawei Versatile Routing Platform Software VRP' );
    $this->setOsVersion( $matches[1] );
    $this->setOsDate( null );
}

But I don't think it worked.
