Je me suis rendu \u00e0 Detroit en octobre pour mettre en place une \u00e9valuation client d’AMF pour un r\u00e9seau assez grand. Tout d’abord, qu’est-ce que l’AMF?<\/p>\n

AMF est un cadre de supervision int\u00e9gr\u00e9 dans les syst\u00e8mes d\u2019exploitation de nos produits. Ce n\u2019est pas comme le provisionnement sans contact de la concurrence. Au lieu de cela, AMF est int\u00e9gr\u00e9 et activ\u00e9 par d\u00e9faut dans nos produits AlliedWare Plus\u2122. Les concurrents de l’industrie ont besoin de serveurs externes pour fournir les configurations et les logiciels via une requ\u00eate DHCP.<\/p>\n

AMF signifie “Autonomous Management Framework\u2122” (Cadre de gestion autonome) , ce qui d\u00e9crit bien ce qu\u2019elle fait. Les commutateurs et les routeurs int\u00e8grent un logiciel intelligent, presque une intelligence artificielle, qui permet au r\u00e9seau d’\u00eatre autonome: il peut auto-corriger, configurer, mettre \u00e0 niveau et r\u00e9agir aux environnements qui l’entourent.<\/p>\n

J’adore vendre et pr\u00e9senter AMF. Il r\u00e9sout vraiment un probl\u00e8me s\u00e9rieux sur les sites des clients. Les clients doivent g\u00e9n\u00e9ralement d\u00e9penser beaucoup d\u2019argent dans l\u2019installation du r\u00e9seau. Habituellement, ils d\u00e9pensent beaucoup d\u2019argent dans les frais d\u2019exploitation en cours pour disposer de syst\u00e8mes et de personnels qualifi\u00e9s leur permettant de g\u00e9rer un vaste r\u00e9seau de commutateurs Ethernet<\/a>.<\/p>\n

Mais ne serait-il pas utile que le r\u00e9seau:<\/p>\n

    \n
  1. Se sauvegarde seul chaque jour, int\u00e9grant les changements de firmware et de configuration.<\/li>\n
  2. S’auto corrige. J’entends par l\u00e0 qu’un commutateur de remplacement se configure automatiquement \u00e0 la mise sous tension. Pensez vrai sans contact!<\/li>\n
  3. Auto-provisionne les nouveaux commutateurs ajout\u00e9s au r\u00e9seau en clonant les configurations de commutateurs existantes.<\/li>\n
  4. Automatise les mises \u00e0 niveau du firmware en me permettant de sp\u00e9cifier le firmware et les p\u00e9riph\u00e9riques que je souhaite mettre \u00e0 niveau, puis effectue la mise \u00e0 niveau \u00e0 la date de mon choix.<\/li>\n
  5. Me permette de configurer plusieurs appareils en m\u00eame temps afin de gagner du temps et de faire moins d’erreurs!<\/li>\n<\/ol>\n

    AMF fait \u00e7a et bien plus encore. C’est rentable, cela permet au client d’\u00e9conomiser de l’argent et donne aux utilisateurs une tranquillit\u00e9 d’esprit. Cela me rend l’esprit tranquille, car je sais que m\u00eame des techniciens r\u00e9seau non qualifi\u00e9s solutionneront des pannes mat\u00e9rielles en quelques minutes, faisant d’AMF le h\u00e9ros de leur gestion du r\u00e9seau. Si vous disposez d’un commutateur de remplacement, il fonctionnera avec les anciennes licences, la configuration et les fichiers en m\u00e9moire flash en moins de 10 minutes. Vous pouvez difficilement demander mieux!<\/p>\n

    Comment AMF fonctionne<\/h2>\n

    AMF a besoin d\u2019une sorte de master AMF pour contr\u00f4ler son fonctionnement. G\u00e9n\u00e9ralement, sur les petits r\u00e9seaux, un commutateur ou routeur peut servir de switch AMF principal et collecter les configurations, lesfirmwares et les fichiers de licence sur une cl\u00e9 USB connect\u00e9e. Les r\u00e9seaux peuvent \u00e9galement avoir un master AMF de backup en cas de d\u00e9faillance du master AMF principal.<\/p>\n

    Sur les grands r\u00e9seaux, o\u00f9 nous devons g\u00e9rer plus de 20 commutateurs, nous pouvons avoir besoin que le master AMF r\u00e9side virtuellement dans une appliance de serveur.<\/p>\n

    Dans ce cas particulier, le client a install\u00e9 notre logiciel AMF Master sur un PC desktop modeste sous Windows et Oracle VirtualBox. Nous avons virtualis\u00e9 le master AMF car il se peut qu’il y ait plus de 300 commutateurs pris en charge par le master AMF. J’ai pens\u00e9 que le meilleur environnement \u00e9tait un master AMF virtualis\u00e9 pour ce sc\u00e9nario du client.<\/p>\n

    Jour 1<\/strong><\/p>\n

    Il s\u2019agissait d\u2019un r\u00e9seau actif, donc toute interruption de service devait \u00eatre nulle ou planifi\u00e9e \u00e0 l\u2019avance via des processus de contr\u00f4le des modifications client afin de minimiser les temps d’interruption.<\/p>\n

    J’ai mis \u00e0 jour le logiciel sur les commutateurs et les routeurs du client. Ensuite, j’ai install\u00e9 le master AMF, dans ce cas une appliance Virtual AMF (VAA), dans une partition Oracle VirtualBox. J’ai continu\u00e9 en installant Vista Manager EX\u2122 (l’interface graphique utilisateur pour AMF) dans une autre partition VirtualBox sur le PC x86 fourni. J’ai suivi les guides d’installation et n’ai rencontr\u00e9 aucun probl\u00e8me. Comme AMF n\u00e9cessite une licence, nous avons fourni une licence 20 n\u0153uds, limit\u00e9e dans le temps, pour permettre au client d’\u00e9valuer AMF.<\/p>\n

    Jour 2<\/strong><\/p>\n

    J’ai configur\u00e9 les commutateurs et les routeurs destin\u00e9s \u00e0 ex\u00e9cuter un environnement AMF. Il m’a fallu moins de deux heures pour configurer les commutateurs et les routeurs pour cette \u00e9valuation. Les commandes utilis\u00e9es pour les p\u00e9riph\u00e9riques AMF de p\u00e9riph\u00e9rie \u00e9taient simplement:<\/p>\n

      \n
    • atmf network-name customer-name<\/strong><\/li>\n
    • interface port1.0.x<\/strong> o\u00f9 x est le port switch qui connecte le commutateur au r\u00e9seau AMF<\/li>\n
    • switchport atmf-link<\/strong><\/li>\n<\/ul>\n

      \u00c0 midi, nous avions sauvegard\u00e9 tous les commutateurs dans le master AMF principal, sur l’appliance Virtual AMF (VAA).<\/p>\n

      Jour 3<\/strong><\/p>\n

      Ce fut une journ\u00e9e amusante pour tester et d\u00e9panner AMF.<\/p>\n

      Comment simuler une machine en panne: R\u00e9initialisez les commutateurs aux valeurs d’usine et observez, via la console RS232, l’auto-provisionnement du commutateur.<\/p>\n

      Comment tester la mise en place d’un nouveau commutateur: clonez la configuration de commutateur existante et connectez un nouveau commutateur de la s\u00e9rie x230.<\/p>\n

      R\u00e9sultats<\/strong><\/p>\n

      Tout a parfaitement fonctionn\u00e9! Le client a \u00e9t\u00e9 surpris de voir le nouveau commutateur sorti d’usine r\u00e9cup\u00e9rer ses fichiers de configuration et de script, le tout en 7 minutes.<\/p>\n

      Nous avons vu comme si un nouveau commutateur x230 avait \u00e9t\u00e9 raccord\u00e9 au r\u00e9seau. La configuration clon\u00e9e a \u00e9t\u00e9 charg\u00e9e automatiquement sur ce nouveau commutateur, y compris les VLAN. Le client \u00e9tait absolument ravi.<\/p>\n

      \u00c0 la fin de la semaine, le client avait achet\u00e9 une licence AMF pour l\u2019ensemble du r\u00e9seau. Le client a \u00e9galement achet\u00e9 Vista Manager EX pour pouvoir voir l’\u00e9tat du r\u00e9seau sur une carte topologique dans l’interface graphique utilisateur.<\/p>\n

      Essayez-le. J’aimerais beaucoup vous aider \u00e0 configurer AMF sur votre r\u00e9seau AlliedWare Plus\u2122. AMF fonctionne, tout simplement. C’est tr\u00e8s rassurant de savoir que le r\u00e9seau se r\u00e9tablira automatiquement en cas de probl\u00e8me.<\/p>\n","protected":false},"excerpt":{"rendered":"
