Test Plan Steps
Step 1. Identify processes and versions
A site administrator enumerates processes on each of the server host, the Control VM, the VMOC VM, etc. and an experimental node configured for OpenStack, which listen for network connections from other nodes, identifies what version of what software package is in use for each, and verifies that we know the source of each piece of software and could get access to its source code.
First get supported versions for the AM API and verify access to resources:
$ omni.py getversion -a gram -V3 INFO:omni:Loading config file /home/lnevers/.gcf/omni_config INFO:omni:Using control framework gram INFO:omni:Substituting AM nickname gram with URL https://128.89.91.170:5001, URN unspecified_AM_URN INFO:omni:Substituting AM nickname gram with URL https://128.89.91.170:5001, URN unspecified_AM_URN INFO:omni:AM URN: unspecified_AM_URN (url: https://128.89.91.170:5001) has version: INFO:omni:{ 'geni_ad_rspec_versions': [ { 'extensions': [], 'namespace': 'http://www.geni.net/resources/rspec/3', 'schema': 'http://www.geni.net/resources/rspec/3/ad.xsd', 'type': 'GENI', 'version': '3'}], 'geni_api': 3, 'geni_api_versions': { '2': 'https://boscontroller.gpolab.bbn.com:5002', '3': 'https://boscontroller.gpolab.bbn.com:5001'}, 'geni_credential_types': [{ 'geni_type': 'geni_sfa', 'geni_version': '3'}], 'geni_request_rspec_versions': [ { 'extensions': [], 'namespace': 'http://www.geni.net/resources/rspec/3', 'schema': 'http://www.geni.net/resources/rspec/3/request.xsd', 'type': 'GENI', 'version': '3'}]} INFO:omni: ------------------------------------------------------------ INFO:omni: Completed getversion: Options as run: aggregate: ['gram'] api_version: 3 framework: gram noGetVersionCache: True Args: getversion Result Summary: Got version for https://128.89.91.170:5001 INFO:omni: ============================================================
Then verify that resources are available for experimenters:
$ omni.py listresources -a gram -o
Note: Fails with ticket #53
Based on the OpenGENI Network and Software Architecture Description document, the following are major services for OpenGENI:
- gram-ch - a test clearinghouse to be replaced by GENI clearinghouse.
- gram-am - the aggregate manager that handles AM API calls for resources
- gram-vnoc - VMOC controller that manages OpenFlow traffic for switch(es) and experimenter controller(s).
- gram-ctrl- Default controller that performs layer 2 MAC to port learning.
The OpenGENI software is installed in /home/gram/gram on the control node (128.89.91.170) and the OpenGENI services listed above are started by scripts in the /home/gram/gram/src/services directory. All services were verified to be running.

Note: There are 3 configured compute nodes, but only two are being used. boscompute4 not working and needs to be restored.
Access to code is possible as follows:
- on the OpenGENI nodes, source is available in /home/gram/gram/src.
- on the git repository git@superior.bbn.com:gram.git and credentials can be requested from gram-dev@bbn.com.
Note: GIT repository is currently internal only

Step 2. Review control network configuration
A site administrator reviews the configuration of the rack control plane switch and verifies that each experimental node's control and console access interfaces are on the expected VLANs. According to OpenGENI Network and Software Architecture Description document interfaces are configured as follows on the OpenGENI nodes:
- eth0: Control network configured for 10.10.8.0/24
- eth1 : Data network configured for 10.10.5.0/24
- eth2 : External network configured for 128.89.91.0/27
- eth3 : Management network configured for 10.10.6.0/24
Control Node

Step 3. Review MAC address
A site administrator reviews the MAC address table on the control plane switch, and verifies that all entries are identifiable and expected.
On the control node listed all MAC addresses on the control network interface (eth0):
lnevers@boscontroller:/var$ arp -i eth0 Address HWtype HWaddress Flags Mask Iface boscompute4.local ether 78:2b:cb:51:a6:82 C eth0 boscompute1.local ether 78:2b:cb:4f:62:6c C eth0 boscompute2.local ether 78:2b:cb:50:5c:00 C eth0
On compute node 1 listed all MAC addresses on the control network interface (eth0):
lnevers@boscompute1:~$ arp -i eth0 Address HWtype HWaddress Flags Mask Iface boscontroller.local ether 78:2b:cb:50:68:01 C eth0
On compute node 2 listed all MAC addresses on the control network interface (eth0):
lnevers@boscompute2:~$ arp -i eth0 Address HWtype HWaddress Flags Mask Iface boscontroller.local ether 78:2b:cb:50:68:01 C eth0
On compute node 4 listed all MAC addresses on the control network interface (eth0):
lnevers@boscompute4:~$ arp -i eth0 Address HWtype HWaddress Flags Mask Iface boscontroller.local ether 78:2b:cb:50:68:01 C eth0
The above ARP entries show that only expected MAC addresses are in use:
- control node has MAC 78:2b:cb:50:68:01 on eth0.
- compute node 1 has MAC 78:2b:cb:4f:62:6c on eth0
- compute node 2 has MAC 78:2b:cb:50:5c:00 on eth0
- compute node 4 has MAC 78:2b:cb:51:a6:82 on eth0
