If you subsequently upload the configuration data from the CPU to a PG you will always
obtain the configuration data that was previously on the CP (with parameters, connections,
IP address).

Memory reset - ACL (access control list) / firewall / VPN configuration
After a memory reset on the module, the following applies:
• ACL or firewall configurations remain active.

If you run a memory reset a CPU as of version 5.2, the CP memory is also reset if you are

After resetting memory, the CP retains the configured MAC address, the IP address and the
retentive parameters (for information on the retentive parameters, refer to section CPLUG

the IP address.
The configuration data is retained on the CPU.
