If IKE policies are not defined, the controller uses the default policy (with a default priority of
10001) and contains the default values. When IKE negotiations begin, the peer initiating the
negotiation sends its policies to the remote peer. The remote peer searches for a match with its
own policies using the defined priority scheme.
A IKE policy matches when they have the same encryption, hash, authentication and Diffie-Hellman
settings. The SA lifetime must also be less than or equal to the lifetime in the policy sent. If the
lifetimes do not match, the shorter lifetime applies. If no match exists, IKE refuses negotiation.
To view the current set of IKE policies:
1. Select Security > IKE Settings from the main menu tree.
2. Click the IKE Policies tab.
