Analysis
Certain IPsec policy settings of the responder are incorrect. Verify the settings as follows:
1. Use the display ike sa verbose command to verify that matching IKE profiles were found in
IKE negotiation phase 1. If no matching IKE profiles were found and the IPsec policy has an IKE
profile specified, the IPsec SA negotiation fails.
# Verify that matching IKE profiles were found in IKE negotiation phase 1.
