Este documento fornece informações para entender as depurações de IKEv2 no Adaptive Security Appliance (ASA) quando a chave pré-compartilhada (PSKs) é usada.
Não existem requisitos específicos para este documento.
Este documento não se restringe a versões de software e hardware específicas.
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.

A troca de pacotes em IKEv2 é radicalmente diferente do que era em IKEv1. Enquanto no IKEv1 havia uma troca de fase1 claramente demarcada que consistia em 6 pacotes seguidos de uma troca de fase 2 que consistia em 3 pacotes, a troca de IKEv2 é variável. Para obter informações mais detalhadas sobre as diferenças e uma explicação da troca de pacotes, consulte IKEv2 Packet Exchange and Protocol Level Debugging.
