[SFC-148] Missing actions in SFF egress flows

Thu, 19 Oct 2017 21:26:58 +0000

The following actions are missing in egress flows:

move:NXM_NX_NSI[]->NXM_NX_NSI[],
move:NXM_NX_NSP[]->NXM_NX_NSP[],
move:NXM_NX_NSH_C1[]->NXM_NX_TUN_IPV4_DST[],
move:NXM_NX_NSH_C2[]->NXM_NX_TUN_ID[0..31]

Example:
Should be
cookie=0xba5eba11ba5eba11, duration=148.460 table=15, n_packets=150 n_bytes=1195, priority=650,nsp=95,nsi=253 actions=move:NXM_NX_NSI[]~~>NXM_NX_NSI[],move:NXM_NX_NSP[]~~>NXM_NX_NSP[],move:NXM_NX_NSH_C1[]~~>NXM_NX_TUN_IPV4_DST[],move:NXM_NX_NSH_C2[]~~>NXM_NX_TUN_ID[0..31],IN_PORT
But is
cookie=0xba5eba11ba5eba11, duration=9.303s, table=15, n_packets=48, n_bytes=3552, priority=751,nsp=95,nsi=253,in_port=1 actions=IN_PORT

I looked into configureVxlanGpeLastHopTransportEgressFlow method here on line 1085 (priority of flows are FLOW_PRIORITY_TRANSPORT_EGRESS + 1)

And I noticed, that all the missing actions are actually being configured.
Therefore it's possible that the problem may also be caused by Openflowplugin.

The misconfigured flow can be seen here:

please notice the flow
priority 751,table=15,nsi=253,...

Nodes config and operational DS can be also seen on robot output:

nodes operational:
