Linguaggio senza pregiudizi

La documentazione per questo prodotto è stata redatta cercando di utilizzare un linguaggio senza pregiudizi. Ai fini di questa documentazione, per linguaggio senza di pregiudizi si intende un linguaggio che non implica discriminazioni basate su età, disabilità, genere, identità razziale, identità etnica, orientamento sessuale, status socioeconomico e intersezionalità. Le eventuali eccezioni possono dipendere dal linguaggio codificato nelle interfacce utente del software del prodotto, dal linguaggio utilizzato nella documentazione RFP o dal linguaggio utilizzato in prodotti di terze parti a cui si fa riferimento. Scopri di più sul modo in cui Cisco utilizza il linguaggio inclusivo.

Verifica

Per verificare che la configurazione funzioni correttamente, consultare questa sezione.

Lo strumento Output Interpreter (solo utenti registrati) (OIT) supporta alcuni comandi show. Usare l'OIT per visualizzare un'analisi dell'output del comando show.

  • show crypto isakmp sa: visualizza tutte le associazioni di sicurezza IKE correnti in un peer.

  • show crypto ipsec sa: visualizza tutte le SA IPsec correnti.

In questa sezione vengono illustrati esempi di configurazioni di verifica per:

Risoluzione dei problemi

Le informazioni contenute in questa sezione permettono di risolvere i problemi relativi alla configurazione.

Utilizzare i seguenti comandi come illustrato:

  • clear crypto isakmp sa: cancella le SA della fase 1.

    caution Attenzione: il comando clear crypto isakmp sa è intrusivo e cancella tutti i tunnel VPN attivi. A partire dalla versione 8.0(3) del software PIX/ASA, una singola associazione di protezione IKE può essere cancellata usando il comando clear crypto isakmp sa <indirizzo ip peer> . Prima della versione software 8.0(3), il comando vpn-sessiondb logoff tunnel-group <tunnel-group-name> può essere usato per cancellare le associazioni di sicurezza IKE e IPsec per un singolo tunnel. 

    ASA5505#vpn-sessiondb logoff tunnel-group 192.168.1.1 
Do you want to logoff the VPN session(s)? [confirm] Y
INFO: Number of sessions from TunnelGroup "192.168.1.1" logged off : 1
