[OVSDB-239] 'ifindex' column from Interface table on OVS

Thu, 30 Jun 2016 00:35:28 +0000

On Groupbasedpolicy, we have some demo setups involving OVS switches running Docker containers locally.
On the switch, Interface table contains column "ifindex", its value visible with
ovs-vsctl list Interface:

sudo ovs-vsctl --columns _uuid,name,ifindex,ofport list Interface
_uuid : 2314250c-8cd5-48a6-95a8-b2549103b434
name : "vethl-h35_2"
ifindex : 17
ofport : 3
...

But this key-value pair is not present in the Datastore:

http://localhost:8181/restconf/operational/network-topology:network-topology/topology/ovsdb:1/

...
"termination-point": [

{ "tp-id": "vethl-h35_2", "ovsdb:name": "vethl-h35_2", "ovsdb:interface-uuid": "2314250c-8cd5-48a6-95a8-b2549103b434", "ovsdb:port-uuid": "c4532a19-7357-42c5-9150-5daf50e8ba4e", "ovsdb:ofport": 3 }

,
...

I think it was not requested by anyone before, but now we are collecting flow statistics with sFlow, which uses ifIndex for our endpoins, so having this in the DS along with other data will help us to map "ifindex" to "ofport" and not to invent workarounds.
