Langage exempt de préjugés

Dans le cadre de la documentation associée à ce produit, nous nous efforçons d’utiliser un langage exempt de préjugés. Dans cet ensemble de documents, le langage exempt de discrimination renvoie à une langue qui exclut la discrimination en fonction de l’âge, des handicaps, du genre, de l’appartenance raciale de l’identité ethnique, de l’orientation sexuelle, de la situation socio-économique et de l’intersectionnalité. Des exceptions peuvent s’appliquer dans les documents si le langage est codé en dur dans les interfaces utilisateurs du produit logiciel, si le langage utilisé est basé sur la documentation RFP ou si le langage utilisé provient d’un produit tiers référencé. Découvrez comment Cisco utilise le langage inclusif.

À propos de cette traduction

Cisco a traduit ce document en traduction automatisée vérifiée par une personne dans le cadre d’un service mondial permettant à nos utilisateurs d’obtenir le contenu d’assistance dans leur propre langue.

Introduction

Ce document fournit un exemple de configuration pour l'interface BRI (Basic Rate Interface) RNIS et illustre le comportement du routeur Cisco en ce qui concerne le processus de négociation de l'identificateur de terminal (TEI).

Conditions préalables

Conditions requises

Aucune spécification déterminée n'est requise pour ce document.

Components Used

Les informations contenues dans ce document sont basées sur les versions de matériel et de logiciel suivantes :

  • Cisco IOS ? Version du logiciel 12.2(6).

  • Toutes les plates-formes matérielles.

Remarque : La commande isdn tei-negotiation keep a été introduite dans le logiciel Cisco IOS Versions 12.2(6) et 12.2(6)T.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

Pour plus d'informations sur les conventions des documents, référez-vous aux Conventions utilisées pour les conseils techniques de Cisco.

Informations générales

Dans certains pays européens (comme la Belgique et les Pays-Bas), la pratique habituelle est que la compagnie de téléphone (Telco) déconnecte la couche 1 RNIS lorsque la ligne BRI n’est pas active depuis un certain temps, pour des raisons d’économie d’énergie. Ces alternatives sont possibles :

  • Les TEI qui ont déjà été attribués peuvent être préservés après que la couche 1 cesse de clignoter.

  • Le logiciel Cisco IOS peut être configuré pour négocier à nouveau le TEI chaque fois que la couche 1 tombe en panne.

Configuration

Cette section vous fournit des informations pour configurer les fonctionnalités décrites dans ce document.

Remarque : Pour en savoir plus sur les commandes utilisées dans le présent document, utilisez l’outil de recherche de commandes (clients inscrits seulement).

Diagramme du réseau

Ce document utilise la configuration réseau suivante :

Vérification

Cette section présente des informations que vous pouvez utiliser pour vous assurer que votre configuration fonctionne correctement.

Certaines commandes show sont prises en charge par l'Output Interpreter Tool (clients enregistrés uniquement), qui vous permet de voir une analyse de la sortie de la commande show.

  • show isdn status ? ? affiche l’état de toutes les interfaces RNIS.

Dépannage

Cette section fournit des informations que vous pouvez utiliser pour dépanner votre configuration.

Dépannage des commandes

Remarque : avant d'émettre des commandes debug, reportez-vous à Informations importantes sur les commandes de débogage.

  • debug isdn q921 ???affiche les procédures d’accès de couche liaison de données (couche 2) qui se déroulent au niveau du routeur sur le canal D (LAPD) de son interface RNIS.

  • debug isdn q931 ???affiche des informations sur la configuration et le retrait des connexions réseau RNIS (couche 3) entre le routeur local (côté utilisateur) et le réseau.

  • debug isdn events ? ? affiche les événements RNIS qui se produisent du côté utilisateur (sur le routeur) de l’interface RNIS.

  • debug bri ???affiche les informations de débogage sur l’activité de routage RNIS BRI.

Voici la sortie de débogage sur kevin :
