================================================
Install IPsec Policy Operator System Application
================================================
The ipsec-policy-operator system application is managed by the system
application framework and will be automatically uploaded after the system is
deployed. It can be installed by applying the system application and running
the following command:
.. code:: none
~(keystone_admin)$ system application-apply ipsec-policy-operator
Once the system application is installed, ``ipsecpolicies.starlingx.io`` |CRD|
will be created.
.. note::
Configuring IPSec policies on podtopod traffic may degrade the CPU
performance. Refer to the following approximate pod and node impacts for
both transmitting and receiving sides based on the traffic rate between 25
Mbps and 500 Mbps.
+-----+--------------+-------------+
| | Transmit | Receive |
+-----+--------------+-------------+
| Pod | 50-100% | 0% |
+-----+--------------+-------------+
| Node| 30-90% | 5-40% |
+-----+--------------+-------------+
Ensure that adequate resources are available to support sustained and peak
internode traffic.
