Prepare the Site

Before you begin

Note the following details before preparing the site for installing the EFA OpenStack Neutron plug-in:

EFA IP Address (Where EFA is running)
EFA Port number (80)
EFA auth Token (extremenetworks_user_auth_key)
Region_name (RegionOne)
Server interface name that is connected to fabric (eth2 or bond0)

Procedure

Download the EFA plug-in debian packages TAR file for OpenStack from https://extremeportal.force.com/.
Untar and extract the TAR file on the required network node.
```
tar xvzf-efa-neutron-plugins-2.1.0-1.tar.gz
```

Configure the Compute Provider Network and server connections.

Note

All network and server connection settings and mappings can be saved to csv files for bulk configuration using the startup file option in the ml2_conf_extreme.ini file.

Set Name resolution for Controller, Compute, and Networking nodes in /etc/hosts.
Note
Ensure that all OpenStack nodes have unique hostnames.
```
10.24.51.114 OpenStack114
10.24.51.115 OpenStack115
```
Configure the ovs bridge name in the ovs configuration file.
Note
Ensure that the name of the bridge matches with the one configured as bridge_mappings in ml2_conf.ini.
```
sudo ovs-vsctl add-br br0
```
Add physical data ports or bond to the ovs bridge as required.
- Bonding: sudo ovs-vsctl add-bond br0 bond0 eno2 eno3 lacp=active
- Single port: sudo ovs-vsctl add-port br0 eno2
