crypto-ikev1/ikev2-policy commands

crypto

Defines crypto-IKEv1/IKEv2 commands in detail

IKE protocol is a key management protocol standard used in conjunction with IPSec. IKE enhances IPSec by providing additional features, flexibility, and configuration simplicity for the IPSec standard. IKE automatically negotiates IPSec SAs and enables secure communications without time consuming manual pre-configuration.

Use the (config) instance to configure IKEv1/IKEv2 policy configuration commands.

To navigate to the IKEv1/IKEv2 policy config instance, use the following commands:

<DEVICE>(config)#profile <DEVICE-TYPE> <PROFILE-NAME>
<DEVICE>(config-profile-<PROFILE-NAME>)#crypto ikev1/ikev2 policy <IKEV1/IKEV2-POLICY-NAME>

nx9500-6C8809(config-profile-default-rfs4000)#crypto ikev1 policy ikev1-testpolicy

Note

Note

IKEv2 being an improved version of the original IKEv1 design, is recommended in most deployments. IKEv2 provides enhanced cryptographic mechanisms, NAT and firewall traversal, attack resistance, etc.

The following table summarizes crypto IKEv1/iKEv2 configuration mode commands:

Command Description
dpd-keepalive Sets DPD keep alive packet interval
dpd-retries Sets the maximum number of attempts for sending DPD keep alive packets (applicable only to the IKEv1 policy)
isakmp-proposal Configures ISAKMP proposals
lifetime Specifies how long an IKE SA is valid before it expires
mode Sets the mode of the tunnels (applicable only to the IKEv1 policy)
no Removes or reverts IKEv1/IKEv2 policy settings
