Jump to: navigation, search

Getting Networking right in a cloud deployment, is one of the hardest parts and usually needs several deployment iterations.

General

When doing your first deployments, first try to get the simplemost setup working. That is, use the default 'single' mode in crowbar's network.json instead of 'dual' or 'team', use default openvswitch+gre in neutron barclamp (or linuxbridge+vlan mode if you do not need SDN).

Switch configuration

Assuming you use VLAN 84 for admin network, VLAN 85 for public network and VLAN 82-86 overall for this cloud's admin/public/storage/sdn/fixed networks

And assuming your nodes are connected to switch ports 5-9, you use the default IP ranges from network.json and your upstream router IP is 192.168.0.1

# repeat for 82 to 86

# end repeat
# repeat the below for interfaces 6-9
interface Ethernet1/5
switchport mode trunk

switchport trunk native vlan 84
switchport trunk allowed vlan 82-86
# for older Catalyst series
spanning-tree portfast trunk
# for newer Nexus series
spanning-tree port type edge trunk
# repeat end
