Description

After creating the opte-ddm-x2 topo and setting up TGs: send ping from 10.0.0.1 to 10.0.0.3. Then dump the UFT for the 10.0.0.1 port (on sled1). Notice there is an inbound flow from 10.0.0.1: that shouldn't be there.

root@sled1:/opt/cargo-bay# ./opteadm dump-uft -p xde0

Research direction

Reproduce the opte-ddm-x2 testbed flow by pinging 10.0.0.1 to 10.0.0.3, then run ./opteadm dump-uft -p xde0 on sled1. Inspect how the UFT records inbound and outbound ICMP flows; done means the 10.0.0.1 port no longer shows the unexpected inbound flow while the expected outbound flow remains.
