This document provides information to understand debugs on the Cisco IOS® software when the main mode and pre-shared key (PSK) are used.
This document also provides information on how to translate certain debug lines in a configuration.
These topics are not discussed:
IKE and IPSec debugs tend to get cryptic. Cisco Technical Assistance Center (TAC) often uses these bugs to understand where a problem with the IPSec VPN tunnel establishment is located.
The main mode is typically used between LAN-to-LAN tunnels, or in case of remote access (ezvpn) when certificates are used for authentication.
Those debugs are from a Cisco IOS device that runs the 15.2(1)T software release.
Two main scenarios are described in this document:
In this document, a VTI-based tunnel between two sites is established, based on IPv6.
