Dear All,
I tried to dump the flows on the openflow switch. But could not succeed. The
log file of the openflow switch is as follows when I run the continuous
ping from host1 to host2 which is connected to openflow swtich.

When I tried to dump the tables it shows that
./dpctl dump-tables nl:0
stats_reply (xid=0xd1f2ad7d): flags=none type=3(table)
2 tables
0: hash2 : wild=0x00000, max=131072, active=0
lookup=213458, matched=0
1: linear : wild=0xfffff, max= 100, active=0
lookup=213458, matched=0
And when I tried to dump the flows it shows nothing the flow table
./dpctl dump-flows nl:0
stats_reply (xid=0x1a2ab00a): flags=none type=1(flow)
Any idea why flow table is not populating?
Best Regards,
Waqas Daar
