Over deze vertaling

Cisco heeft dit document vertaald via een combinatie van machine- en menselijke technologie om onze gebruikers wereldwijd ondersteuningscontent te bieden in hun eigen taal. Houd er rekening mee dat zelfs de beste machinevertaling niet net zo nauwkeurig is als die van een professionele vertaler.

Inleiding

Dit document biedt een voorbeeldconfiguratie voor PPP-terugbellen tussen twee Cisco-routers.

Voorwaarden

Vereisten

Er zijn geen specifieke vereisten van toepassing op dit document.

Gebruikte componenten

De informatie in dit document is gebaseerd op de volgende software- en hardware-versies:

  • Cisco IOS®-softwarerelease 12.0(3)T of hoger

Opmerking: Om PPP callback te configureren met de hulp van een AAA server toegewezen callback string, moet u de dialer Aa-opdracht gebruiken, die beschikbaar is in Cisco IOS-softwarerelease 12.0(3)T of hoger. In Cisco IOS-versies 12.1(4)T, 12.2(1)T en later is deze opdracht niet vereist voor PPP-callback met een AAA-server waaraan callback string is toegewezen.

Opmerking: de dialer aaa opdracht wordt alleen ondersteund door Verouderde DDR (zoals getoond in figuur 1).

De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u de potentiële impact van elke opdracht begrijpen.

Achtergrondinformatie

De TACACS+ (AAA server) wordt gebruikt om de callback dialstring aan de callback server te leveren. U kunt echter ook RADIUS gebruiken om de callback string te leveren. Om PPP callback te configureren met lokale verificatie, autorisatie en accounting (AAA), zie PPP-terugbellen via ISDN configureren.

In deze steekproefconfiguratie gebruikt callback PPP en de faciliteiten die in RFC 1570 zijn gespecificeerd. Het PPP-terugbellen via het ISDN-circuit is in deze volgorde voltooid:

  1. De callback client start en voert een ISDN-verbinding naar de callback server router in.

  2. De callback client en de callback server onderhandelen over PPP Link Control Protocol (LCP). In LCP-onderhandeling wordt opgeroepen, onderhandeld en overeengekomen.

  3. De callback client en de callback server authenticeren elkaar met PPP Wachtwoord Verificatieprotocol (PAP) of Challenge Handshake Authentication Protocol (CHAP). U kunt echter wel de callback client configureren om de callback server niet te authenticeren door de Pp-verificatieschakelaar aan te roepen.

  4. De callback server verkrijgt de benodigde callback eigenschappen, zoals het callback dialstring (het telefoonnummer van de client) van de AAA-server.

  5. Beide routers laten de ISDN-verbinding vallen.

  6. De callback server start de callback naar de client. Wanneer de verbinding tot stand is gebracht, authentiseren de routers elkaar en wordt de link gevestigd.

Configuraties

Dit document gebruikt deze configuraties:

  • Freeware TACACS+ configuratie

  • RADIUS-configuratie

  • Configuratie van alternatieve RADIUS

  • Configuratie van TNT-buster (Terugbellen Server)

  • Configuratie van Tremens (terugbellen)

Freeware TACACS+ configuratie 
user = tremens {
  default service = permit
  login = cleartext "cisco"
  chap = cleartext "cisco"
  
!--- CHAP password.

  service = ppp protocol = lcp {
  callback-dialstring = "6083"

 !--- Number to callback.

  send-secret = "cisco"
  }
  }

U kunt RADIUS ook gebruiken als uw AAA-server om de callback-eigenschappen te leveren in plaats van TACACS+. Hier wordt een voorbeeld van de RADIUS-configuratie gegeven:

RADIUS-configuratie 
tremens         Auth-Type = Local, Password = "cisco"
                Service-Type = Framed-User,

 !--- Service-Type(6) is Framed User(4).

                Cisco-AVPair = "lcp:callback-dialstring=6083", 
                Cisco-AVPair = "lcp:send-secret=cisco"

Opmerking: In de RADIUS-configuratie hierboven, is Cisco AVPair lcp:send-geheven=cisco nodig op het moment van verificatie van de callback. Als u deze AVPair niet omvat, moet u de gebruikersnaam en het wachtwoord voor CHAP van de afstandsrouter lokaal op de callback server configureren.

Opmerking: dit document heeft voornamelijk betrekking op TACACS+. De details in dit document tonen geen RADIUS-geïnitieerde callback.

Opmerking: Van Cisco IOS versie 12.1(7) is het mogelijk om de RADIUS-eigenschap 19 van de Internet Engineering Task Force (IETF) voor ISDN en analoge Microsoft callback te gebruiken. In dat geval is het niet nodig om de Cisco AVPstoelen te gebruiken, die in de vorige configuratie zijn weergegeven. Raadpleeg het hier getoonde alternatieve RADIUS-configuratievoorbeeld:

Configuratie van alternatieve RADIUS 
tremens         Auth-Type = Local, Password = "cisco"
                Service-Type = callback framed
                
!--- Service-Type (6) is callback framed (4).

                
!--- Callback framed is also known as !--- Dialback-Framed-User.

                Callback =6083
                
!--- IETF RADIUS Callback attribute (19) with the phone !--- number for the callback.

Opmerking: De RADIUS-uiteinden tonen de RADIUS-kenmerk 19 van IETF dat wordt teruggegeven aan de callback server.

Verifiëren

Deze sectie verschaft informatie die u kunt gebruiken om te bevestigen dat uw configuratie correct werkt.

Bepaalde opdrachten met show worden ondersteund door de tool Output Interpreter (alleen voor geregistreerde klanten). Hiermee kunt u een analyse van de output van opdrachten met show genereren.

  • toon dialer interface type nummer- toont algemene diagnostische informatie voor interfaces ingesteld voor dial-on-demand routing (DDR). De bron- en doeladressen van het pakket dat het draaien in werking heeft gesteld, worden in de regel met de kiesreden weergegeven. Deze opdracht geeft ook de verbindingsptimers weer.

  • toon ISDN status-kunt u verzekeren dat de router goed met de ISDN switch communiceert. In de uitvoer, controleer of Layer 1 Status actief is, en of de Layer 2 Status = MULTIPLE_FRAME_ESTABLISHED verschijnt. Deze opdracht geeft ook het aantal actieve oproepen weer.

Problemen oplossen

Deze sectie bevat informatie waarmee u problemen met de configuratie kunt oplossen.

Raadpleeg de verwijzing naar de Debug Opdrachten van Cisco IOS release 12.0 voor meer informatie over debug opdrachten.

Opdrachten voor probleemoplossing (optioneel)

Bepaalde opdrachten met show worden ondersteund door de tool Output Interpreter (alleen voor geregistreerde klanten). Hiermee kunt u een analyse van de output van opdrachten met show genereren.

Opmerking: Voordat u debug-opdrachten afgeeft, raadpleegt u Belangrijke informatie over Debug Commands.

  • debug ISDN Q931: toont aanroepen, instelling en traag omlaag van de ISDN-netwerkverbinding (Layer 3).

  • debug dialer [ gebeurtenissen | Packet—toont DDR-zuiverende informatie over de pakketten die op een dialerinterface worden ontvangen.

  • debug van verificatie door middel van detectie - geeft informatie weer over AAA-verificatie.

  • debug a autorisatie—geeft informatie weer over AAA autorisatie.

  • debug tacacs-toont gedetailleerde het zuiveren informatie geassocieerd met TACACS+.

  • debug PPP onderhandeling-toont informatie over PPP verkeer en uitwisselingen terwijl de onderhandeling van de componenten PPP, waaronder Link Control Protocol (LCP), Verificatie, en NCP in gang is. Een succesvolle PPP-onderhandeling zal eerst de LCP-staat openen, dan Verifiëren en uiteindelijk NCP onderhandelen.

  • debug van PPP-verificatie—geeft de PPP-verificatieprotocolberichten weer, inclusief Challenge Authentication Protocol (CHAP)-pakketuitwisselingen en Wachtwoord-verificatieprotocol (PAP)-uitwisselingen. Als u een fout waarneemt, controleert u of de gebruikersnaam en het wachtwoord voor CHAP correct zijn ingesteld.

  • debug callback - displays wanneer de router een modem en een chatscript gebruikt om terug te bellen op een eindlijn. Omdat deze opdracht voor modems en chatscripts is, wordt deze niet gebruikt in deze configuratie.
