configuration)
Prerequisites:
Development host with Linux shell.
genisoimage tool installed.
Unpack the 128T/128t-cloud-init-example.tar.gz
archive and check the README file for more details:

README
user-data
meta-data
t128-running.xml
To generate the cloud-init iso image:
>genisoimage -output centos_128t_ci.iso -volid cidata -joliet \
-rock user-data meta-data t128-running.xml
Notes:
user-data and meta-data
files must be kept unchanged.
To update the 128T configuration change the
t128-runing.xml file.
XML is the same file downloaded from 128T web access:
configuration -> Import and Export Configuration ->
Export Configuration -> Download Configuration. The
configuration can be updated from a web interface, downloaded onto the
development host and used in generating a new cloud-init iso
image.
By default, t128-running.xml is configured to pass
all traffic from the LAN to the WAN interface. There is only one change
required for the 128T VNF to work on the user's network:
<rt:next-hop>172.24.15.254</rt:next-hop>
Please change <172.24.15.254> with the IP address of your
Gateway in the t128-running.xml file and generate a new
iso image as described above. For more details about configuring the 128T
VNF please contact 128 Technologies.
