Hi VPP devs, Raj,
We had an issue when configuring classify session for classify table, where
the n_skip_vector value is more than zero. The same issue happens when I am
creating the configuration over API or via vppctl. The match "k:
00000000000000000000000000000000" value is always all zeros in both API and
vppctl responses. I believe it should be "k: 00000000000000000000c0a801020000"
that is the match ip of 192.168.1.2.
Can someone check whether there is a bug and the value is not configured at all
or only the data shown to the user are wrongly interpreted?
I added Raj to copy. He noticed this originally and will try to test the
configuration on his setup.
Raj: If you have more data available after testing, please provide them here.
Thanks
