| oanson | rajivk, ping | 06:25 |
| rajivk | oanson, hi | 06:25 |
| oanson | You mentioned you wanted to discuss VLAN aware VMs | 06:27 |
| rajivk | yes, i am going thorough dragonflow code to know how vlans networking is implemented. So that i can map it to the requirement. | 06:29 |
| rajivk | In neutron they are creating a trunk port and subports for each network trunk port belongs to. | 06:30 |
| oanson | Yes | 06:30 |
| rajivk | And tags are assigned for each port to distinguish among subports and later on they are stripped when packet lands in neutron network. | 06:31 |
| oanson | Yes. And the vlan tag is used to identify in which network it lands | 06:31 |
| rajivk | Now through dragonflow, how vlans are implemented? May be we can tag each port for different vlans | 06:32 |
| rajivk | we don't have create subport like neutron. This is the way i am thinking. | 06:32 |
| oanson | Yes. | 06:32 |
| rajivk | But a complete understanding is missing. How to do it? what are the advantage and disadvanges etc. | 06:33 |
| oanson | OVS/OpenFlow have fields to handle vlans | 06:33 |
| rajivk | What are possible approaches? | 06:33 |
| oanson | One sec, let me load the documentation so I get the field names right :) | 06:33 |
| rajivk | I am looking into them your help will be valuable. | 06:33 |
| oanson | MY thought is that in table 0, when the packet is received, we have classification flows. | 06:34 |
| oanson | My* | 06:34 |
| oanson | It sets the network and source port identifiers on the packet's metadata | 06:34 |
| oanson | OVS/OpenFlow allows you to detect if vlan is used, and what's the tag. I think to detect a vlan tag, you use dl_vlan=<vlan tag> | 06:35 |
| oanson | So you can add a flow like: vlan_tag=<vlang tag>,actions=pop_vlan,set_field:<network ID>->metadata,set_field:<subport ID>->reg6 | 06:36 |
| rajivk | ok, i can tag multiple vlans and if match is found then forward normally. | 06:36 |
| oanson | So you can add a flow like: vlan_tag=<vlang tag>,actions=pop_vlan,set_field:<network ID>->metadata,set_field:<subport ID>->reg6,goto_table(1) | 06:36 |
| oanson | Yes | 06:36 |
| rajivk | Currently only one tag is assigned and assigning multiple tags to the interface is enough. is my understanding correct? | 06:36 |
| oanson | On the egress, you do the reverse. You detect (using REG7, which holds the destination port ID) what's the destination port, and tag it if needed | 06:37 |
| oanson | rajivk, yes, I think so | 06:37 |
| rajivk | How till it impact security groups, routers etc? these has to be identified. | 06:37 |
| oanson | You will know exactly what sub-port you come from (detected in table 0) | 06:38 |
| oanson | So port security will know what are the allowed macs/IP pairs | 06:38 |
| oanson | Security groups app will know what are the applied security groups, and can implement them like every other port | 06:38 |
| oanson | l2/l3 lookup is done using MACs and IPs, so that shouldn't be affected | 06:39 |
| rajivk | You have done all my tasks. :) | 06:39 |
| oanson | I think by mapping the packet to a new port, and treating subports as ports, the only change should be in the classifier and dispatcher | 06:39 |
| oanson | rajivk, :). My predecessors designed the Dragonflow pipeline right. That's why it seems so easy :) | 06:40 |
| rajivk | I think, i will require to add new db models for trunk ports as well and mappings? | 06:41 |
| oanson | Yes. I'm guessing for trunk ports and subports. Or modify loigical ports to know which is a port with a vlan tag, and which is not | 06:41 |
| oanson | But I have to verify I understand the Neutron objects to be sure | 06:42 |
| rajivk | You mean we have to create subports in neutron as well? | 06:43 |
| rajivk | neutron => dragonflow | 06:43 |
| rajivk | neutron port-create --name S1 N1 --subport:parent_id <T-id> | 06:53 |
| rajivk | --subport:vid 10 --subport:vid_type VLAN | 06:53 |
| rajivk | for this command, may be we can add vlans to port only, don't create any port and add VLAN to port specified in parent_id(trunk port). | 06:55 |
