Chapter 35 Configuring IPsec Network Security
Optional IKE Parameter Configuration
Note
When the authentication method is rsa-sig, make sure the identity hostname is configured for IKE
because the IKE certificate has a subject name of the FQDN type.
Optional IKE Parameter Configuration
You can optionally configure the following parameters for the IKE feature:
•
The lifetime association within each policy—The lifetime ranges from 600 to 86,400 seconds. The
default is 86,400 seconds (equals one day). The lifetime association within each policy is configured
when you are creating an IKE policy. See the
“Configuring an IKE Policy” section on page 35-13
.
•
The keepalive time for each peer if you use IKEv2—The keepalive ranges from 120 to 86,400
seconds. The default is 3,600 seconds (equals one hour).
•
The initiator version for each peer—IKE v1 or IKE v2 (default). Your choice of initiator version
does not affect interoperability when the remote device initiates the negotiation. Configure this
option if the peer device supports IKEv1 and you can play the initiator role for IKE with the
specified device. Use the following considerations when configuring the initiator version with FCIP
tunnels:
–
If the switches on both sides of an FCIP tunnel are running MDS SAN-OS Release 3.0(1) or
later, you must configure initiator version IKEv1 on both sides of an FCIP tunnel to use only
IKEv1. If one side of an FCIP tunnel is using IKEv1 and the other side is using IKEv2, the FCIP
tunnel uses IKEv2.
–
If the switch on one side of an FCIP tunnel is running MDS SAN-OS Release 3.0(1) or later and
the switch on the other side of the FCIP tunnel is running MDS SAN-OS Release 2.x,
configuring IKEv1 on either side (or both) results in the FCIP tunnel using IKEv1.
Note
Only IKE v1 is supported to build IPsec between 2.x and 3.x MDS switches.
Caution
You may need to configure the initiator version even when the switch does not behave as an
IKE initiator under normal circumstances. Always using this option guarantees a faster
recovery of traffic flows in case of failures.
Step 9
switch(config-ike-ipsec-policy)#
authentication
pre-share
Configures the authentication method to use
the preshared key (default).
switch(config-ike-ipsec-policy)#
authentication
rsa-sig
Configures the authentication method to use
the RSA signature.
Note
To use RSA signatures for
authentication you must configure
identity authentication mode using the
FQDN (see
Step 3
).
switch(config-ike-ipsec-policy)#
no
authentication
Reverts to the default (
pre-share
).
