Network Ports
Note
The openstack CLI will need to be setup to interact with the FlexiHPC system. Please read Setting up your CLI environment to interact with FlexiHPC to get started.
First we need to get a few details, Network ID we want to connect to the network port to, the Subnet ID we want to connect the IP to and the IP Address we want to assign to the network port unless you want it to be assigned an IP from the DHCP
Run the following command to get the Network ID
+--------------------------------------+--------------------------------+--------------------------------------+
| ID | Name | Subnets |
+--------------------------------------+--------------------------------+--------------------------------------+
| 33d0c11b-b659-4b77-9afc-5676fe965839 | external | 5c2644ad-7253-42f5-ad69-40970b84dea6 |

+--------------------------------------+--------------------------------+--------------------------------------+
Take note of the Network ID and the Subnet ID
Note
For this example we will use the azimuth-demo network so the Network ID: d780f680-9640-430f-813f-dbf2128b445c and the Subnet ID: 70dc21e9-d8f4-4232-bda9-2f0a0d508105
Should you not know the IP range of the subnet run the following command to get the IP address range from that chosen subnet
Example response below using the Subnet ID: 70dc21e9-d8f4-4232-bda9-2f0a0d508105

Take note of the allocation_pools as that will specify the pool of IP addresses
Create a network port
Run the following command to create a network port
openstack port create --network NETWORK_ID --description PORT_DESCRIPTION --fixed-ip subnet=SUBNET_ID,ip-address=IP_ADDRESS --enable PORT_NAME
Using the example IDs we prepared earlier it will look like this
openstack port create --network d780f680-9640-430f-813f-dbf2128b445c --description wiki-network-port --fixed-ip subnet=70dc21e9-d8f4-4232-bda9-2f0a0d508105,ip-address=192.168.100.60 --enable Wiki-Network-Port-CLI
We have specified the Network ID as the azimuth-demo network, with the Subnet ID within that network and assigning that network port an IP address of 192.168.100.60, we also gave it a description and a friendly name.

Should you not want to assign an IP yourself and allow the DHCP to assign it then run the command without the ip-addressparameter like below
openstack port create --network NETWORK_ID --description PORT_DESCRIPTION --fixed-ip subnet=SUBNET_ID --enable PORT_NAME
