Configuring Connection Profiles
Step 3
Specify whether to validate the identity of the peer using the peer’s certificate:
hostname(config-tunnel-ipsec)#
peer-id-validate
option
hostname(config-tunnel-ipsec)#
The available options are
req
(required),
cert (
if supported by certificate), and
nocheck (
do not check).
The default is
req
. For example, the following command sets the peer-id-validate option to
nocheck
:
hostname(config-tunnel-ipsec)#
peer-id-validate nocheck
hostname(config-tunnel-ipsec)#
Step 4
Specify whether to enable sending of a certificate chain. This action includes the root certificate and any
subordinate CA certificates in the transmission:
hostname(config-tunnel-ipsec)#
chain
hostname(config-tunnel-ipsec)#
You can apply this attribute to all tunnel-group types.
Step 5
Specify the name of a trustpoint that identifies the certificate to be sent to the IKE peer:
hostname(config-tunnel-ipsec)#
trust-point
trust-point-name
hostname(config-tunnel-ipsec)#
For example, the following command sets the trustpoint name to mytrustpoint:
hostname(config-tunnel-ipsec)#
trust-point mytrustpoint
hostname(config-tunnel-ipsec)#
You can apply this attribute to all tunnel-group types.
Step 6
Specify the ISAKMP (IKE) keepalive threshold and the number of retries allowed. The
threshold
parameter specifies the number of seconds (10 through 3600) that the peer is allowed to idle before
beginning keepalive monitoring. The
retry
parameter is the interval (2 through 10 seconds) between
retries after a keepalive response has not been received. IKE keepalives are enabled by default. To
disable IKE keepalives, enter the
no
form of the
isakmp
command:
hostname(config)#
isakmp keepalive threshold
<
number
>
retry
<
number
>
hostname(config-tunnel-ipsec)#
For example, the following command sets the ISAKMP keepalive threshold to 15 seconds and sets the
retry interval to 10 seconds:
hostname(config-tunnel-ipsec)#
isakmp keepalive threshold 15 retry 10
hostname(config-tunnel-ipsec)#
The default value for the
threshold
parameter for LAN-to-LAN is 10, and the default value for the retry
parameter is 2.
To specify that the central site (secure gateway) should never initiate ISAKMP monitoring, enter the
following command:
hostname(config-tunnel-ipsec)#
isakmp keepalive threshold infinite
hostname(config-tunnel-ipsec)#
Step 7
Specify the ISAKMP hybrid authentication method, XAUTH or hybrid XAUTH.
You use
isakmp ikev1-user-authentication
command to implement hybrid XAUTH authentication
when you need to use digital certificates for ASA authentication and a different, legacy method for
remote VPN user authentication, such as RADIUS, or SecurID. Hybrid XAUTH breaks phase
1 of IKE down into the following two steps, together called hybrid authentication:
a.
The ASA authenticates to the remote VPN user with standard public key techniques. This
establishes an IKE security association that is unidirectionally authenticated.
