VPN Services may reference IPSEC profiles. Transform sets define the encryption and hash algorithm to be used
by a dynamic map in an IPSEC profile that supports VPN Services.
Navigate to Advanced Services > VPN Services > IPSEC > Dynamic Map > Transform Set from the Dell
PowerConnect W Configuration navigation pane. This page displays all currently configured Transform Sets,
and which Dynamic Maps reference them.

Description
Specify the priority in which this Dynamic Map should be processed in relation to
additional Dynamic Maps that may be configured and used by IPSEC profiles.
Diffie-Hellman is a key agreement algorithm that allows two parties to agree upon a
shared secret, and is used within IKE to securely establish session keys. To set the
Diffie Hellman Group for the ISAKMP policy, click the Diffie Hellman Group drop-
down list and select one of the following groups:
Group 1: 768-bit Diffie Hellman prime modulus group.

 Group 2: 1024-bit Diffie Hellman prime modulus group.
 Group 19: 256-bit random Diffie Hellman ECP modulus group.
Group 20: 384-bit random Diffie Hellman ECP modulus group.

NOTE: 'EC 256-bit (19)' and 'EC 384-bit (20)' require an Advanced Cryptography
license and a minimum version of 6.1.0.0.
Define the lifetime in seconds for the dynamic map, when deployed in IPSEC profiles.
From the drop-down menu, select up to four transform sets in the sequence in which
they should be referenced by the Dynamic Map. You can add a new Transform Set by
clicking the add icon, or you can edit an existing Transform Set by clicking the pencil
icon. Refer to "Advanced Services > VPN Services > IPSEC > Dynamic Map >
Transform Set" on page 166.
Select 1 to configure the VPN for IKEv1, or 2 for IKEv2.
