Usage guidelines
A DH group with a higher group number provides higher security but needs more time for processing.
To achieve the best trade-off between processing performance and security, choose proper DH
groups for your network.
You must specify a minimum of one DH group for an IKEv2 proposal. Otherwise, the proposal is
incomplete and useless.
You can specify multiple DH groups for an IKEv2 proposal. A group specified earlier has a higher
priority.
Examples
# Specify DH groups 1 for the IKEv2 proposal 1.
<Sysname> system-view
[Sysname] ikev2 proposal 1
[Sysname-ikev2-proposal-1] dh group1
