Dit document toont configuratievoorbeelden van een router en een AAA-server om Point-to-Point Protocol (PPP)-terugbellen met TACACS+ te doen. Er zijn twee voorbeelden die het callback-nummer gebruiken dat is opgegeven door de AAA-server of door de Windows 2000-client.
Voer de eerste tests uit met lokale verificatie en callback (verwijder de opdracht aaa new-model). Als callback niet werkt met lokale verificatie, werkt het niet met TACACS+. Raadpleeg MS-callback tussen een router en een Windows-pc configureren voor een voorbeeld van het gebruik van lokale verificatie.
Voer verdere PPP-verificatietests uit met TACACS+ zonder callback. Als gebruikers FAIL-verificatie en/of autorisatie zonder callback weigeren, werken verificatie en autorisatie niet met callback.
Zodra lokale verificatie voor callback- en PPP-verificatie met TACACS+ werkt, voegt u de informatie van de lokale gebruiker op de router (zoals callback dial-string) toe aan het gebruikersprofiel op de server.
Opmerking: de client in deze tests is een Windows 2000 Professional Client, DUN, ingesteld zoals gebruikelijk voor een PPP-verbinding, met Microsoft Callback setup als "Vraag me tijdens het bellen wanneer de server biedt." Microsoft Callback wordt ondersteund in Cisco IOS®-softwarereleases 11.3.2.T en hoger.
Er zijn geen specifieke vereisten van toepassing op dit document.

Dit document gebruikt de netwerkinstallatie die in dit diagram wordt getoond.
Dit zijn de AAA-serverconfiguraties voor PPP-callback met een telefoonnummer dat door de AAA-server is gespecificeerd.
Server instellen - Cisco Secure ACS voor Windows
Als u de LCP-optie voor gebruikers en groepen wilt inschakelen, gaat u naar het scherm Interfaceconfiguratie, selecteert u TACACS+ (Cisco IOS), en zorgt u ervoor dat de opties PPP IP en PPP LCP zijn ingeschakeld voor gebruikers en groepen.
Callback kan worden geconfigureerd in de groep of in de gebruikersinstellingen.
Een groep instellen voor terugbellen: Selecteer in het scherm Groepsinstelling onder Terugbellen de optie Windows Database Terugbellen-instellingen gebruiken (in een oudere versie van ACS staat deze optie bekend als "Microsoft NT-terugbellen instellingen gebruiken"). Controleer vervolgens de opties voor PPP IP en PPP LCP. Selecteer de optie Terugbellen en type 84007 in het lege veld.
Voor een gebruiker die deel uitmaakt van de groep, gaat u naar het scherm Gebruikersinstelling en selecteert u Groepsinstelling gebruiken onder Terugbellen. Klik op Indienen + opnieuw starten.
Een individuele gebruiker voor terugbellen configureren: selecteer in het scherm Gebruikersinstelling onder Terugbellen de optie Terugbellen met behulp van dit nummer en typ 84007 in het lege veld. Controleer vervolgens de opties voor PPP IP en PPP LCP. Klik op Indienen + opnieuw starten.
Serverinstallatie - Cisco Secure UNIX
<coachella>/export/home/brownr> ViewProfile -p 9900 -u callback_user User Profile Information user = callback_user{ profile_id = 113 profile_cycle = 15 member = ccie_study password = chap "********" service=ppp { protocol=ip { } protocol=lcp { set callback-dialstring=84007 } } }
Serverinstallatie - TACACS+ freeware
user = callback_user { chap= cleartext "chapuser" service = ppp protocol = lcp { callback-dialstring=84007 } service = ppp protocol = ip { } }
De voorbeelden in deze documentversie zijn van callback op een vooraf gedefinieerd nummer (gespecificeerd in de AAA-server). Callback kan ook worden gedaan bij een door de gebruiker opgegeven nummer met behulp van het callback-nummer en wordt in de AAA-server als null gespecificeerd. Dit veroorzaakt de router om de gebruiker om een callback aantal te vragen. De eerste tests moeten worden uitgevoerd met de lokale callback-optie. Verwijs naar de asynchrone PPP callback tussen een toegangsserver en een voorbeeld van PC en merk op dat "callback-dialstring" als citaten (") wordt gespecificeerd.
De client in deze tests was een Windows 2000 Professional-client, zoals gebruikelijk ingesteld voor een PPP-verbinding, met Microsoft Callback als "Bel me terug op de onderstaande nummers."
Opmerking: het weergegeven netwerkdiagram en de routerconfiguratie zijn van toepassing op de hier besproken callback-configuraties.
Hier getoond zijn AAA serverconfiguraties voor PPP callback met een telefoonnummer dat door de gebruiker wordt gespecificeerd.
Server instellen - Cisco Secure for Windows
Als u de LCP-optie voor gebruikers en groepen wilt inschakelen, gaat u naar het scherm Interfaceconfiguratie, selecteert u TACACS+ (Cisco IOS), en zorgt u ervoor dat de opties PPP IP en PPP LCP zijn ingeschakeld voor gebruikers en groepen.
Callback kan worden geconfigureerd in de groep of in de gebruikersinstellingen.
Een groep configureren voor terugbellen: op het scherm Group Setup selecteert u onder Terugbellen de optie voor Dialup-client voor terugbellen. Controleer vervolgens de opties voor PPP IP en PPP LCP.
Voor een gebruiker die deel uitmaakt van de groep, gaat u naar het scherm Gebruikersinstelling en selecteert u Groepsinstelling gebruiken onder Terugbellen. Klik op Indienen + opnieuw starten.
Een individuele gebruiker voor callback configureren: in het scherm Gebruikersinstelling onder Terugbellen selecteert u de optie Dialup client specificeert callback nummer. Controleer vervolgens de opties voor PPP IP en PPP LCP. Klik op Indienen + opnieuw starten.
