Summit WM3000 Series Controller System Reference Guide 369
9 If the properties of an existing peer IP address, key and aggressive mode designation are no longer
relevant and cannot be edited, click the Add button to create a new pre-shared key
a Select the Peer IP Address checkbox to associate an IP address with the specific tunnel used by a
group of peers or, select the Distinguished Name checkbox to configure the controller to restrict
access to those peers with the same distinguished name, or select the Hostname checkbox to allow
shared-key messages between corresponding hostnames.
b Define the Key (string ID) a remote peer uses to look up the pre-shared to interact securely with
peers within the tunnel.
c Select the Aggressive Mode checkbox (if required). Aggressive mode enables you to configure IKE
pre-shared keys as Radius tunnel attributes for IP Security (IPSec) peers.
d Refer to the Status field for the current state of requests made from applet. This field displays
error messages if something is wrong in the transaction between the applet and the controller.
e Click OK to use the changes to the running configuration and close the dialog.
f Click Cancel to close the dialog without committing updates to the running configuration.
Setting IKE Policies
Each IKE negotiation is divided into two phases. Phase 1 creates the first tunnel (protecting later IKE
negotiation messages) and phase 2 creates the tunnel protecting the data. To define the terms of the IKE
negotiation, create one or more IKE policies. Include the following:
● An authentication scheme to ensure the credentials of the peers
● An encryption scheme to protect the data
● A HMAC method to ensure the identity of the sender, and validate a message has not been altered
● A Diffie-Hellman group establishing the strength of the of the encryption-key algorithm.
● A time limit for how long the encryption key is used before it is replaced.
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
