MDM site-level configuration
In the site-parameters, include the MDM credentials that you generated when installing MDM,
in the form of a single certificate-type secret.
The field name is mdm-certificate-id.
The secret must have all three parameters included: CA certificate, static certificate, and static private key.
In addition, to access MDM, add one or more public keys from the SSH key pair(s)
to the ssh section of each MDM instance.
MDM service group
Define one service group containing details of all the MDM VMs.
Networks for the MDM service group
MDM requires two traffic types: management and signaling, which must be on separate subnets.
|
MDM v3.8 or later only requires the management traffic type.
Refer to the MDM Overview Guide for further information.
|
Each MDM instance needs one IP address on each subnet.
The management subnet does not necessarily have to be the same
as the management subnet that the RVT VMs are assigned to,
but the network firewalling and topology does need to allow for communication
between the RVT VMs' management addresses and the MDM instances' management addresses,
and as such it is simplest to use the same subnet as a matter of practicality.
Product options for the MDM service group
For MDM product options, you must include the consul token and custom topology data.
-
The consul token is an arbitrary, unique string of up to 40 characters (for example, a UUID). Generate it once during MDM installation.
|
|
If you are using MDM version 3.0.1 or later, you must specify the consul token as a freeform-type secret.
Add it to QSG along with the credentials (certificates and key).
In the example snippet of the SDF below, replace the field |
-
The custom topology data is a JSON blob describing which VNFCs in the deployment communicate with which other VNFCs through MDM. See the example below. You need to add an entry for group name
DNSwith no neighbours, and one for each node type in the deployment with the neighbourSAS-DATA. The VMs will be unable to communicate with MDM if the topology is not configured as described.

|
The |
Use YAML’s |- block-scalar style for the JSON blob, which will keep all newlines
except the final one.
Overall, the product options should look like this:
vnfcs:
...
- name: mdm
product-options:
mdm:
consul-token: 01234567-abcd-efab-cdef-0123456789ab
