Install Dependencies. + +To support the framework dependencies the following packages must be installed. +The example provided is based on Ubuntu and needs to be executed in root mode. + +:: + + apt-get install python-dev + apt-get install python-pip + apt-get install python-mock + apt-get install tcpreplay + apt-get install libpcap-dev + +2.

Create Two Networks based on VLANs in Neutron. + +To enable network communications between the packet generator and the compute +node, two networks must be created via Neutron and mapped to the VLAN IDs +that were previously used in the configuration of the physical switch. +The following shows the typical set of commands required to configure Neutron +correctly. +The physical switches need to be configured accordingly. + +:: + + VLAN_1=2032 + VLAN_2=2033 + PHYSNET=physnet2 + neutron net-create apexlake_inbound_network \ + --provider:network_type vlan \ + --provider:segmentation_id $VLAN_1 \ + --provider:physical_network $PHYSNET + + neutron subnet-create apexlake_inbound_network \ + 192.168.0.0/24 --name apexlake_inbound_subnet + + neutron net-create apexlake_outbound_network \ + --provider:network_type vlan \ + --provider:segmentation_id $VLAN_2 \ + --provider:physical_network $PHYSNET + + neutron subnet-create apexlake_outbound_network 192.168.1.0/24 \ + --name apexlake_outbound_subnet + + +5.
