Hey,
I met the same issue when I using latest VPP code.
In VPP 17.01, CLI command “classify table mask l3 ip4 proto” works well.
Below is the error and bt log:
Could someone take a look at it? Thanks a lot.
DBGvpp# classify table match 1 mask l3 ip4 proto

Subject: [vpp-dev] problem in classify command in vpp
Hi all.
I am new in VPP and I'm trying to use classify command to filter specific
traffic. I've followed [vpp-dev] Question: Classification with hex
mask<https://lists.fd.io/pipermail/vpp-dev/2016-June/001408.html>. At first, I
entered this command:
vpp# classify table mask l3 ip4 src dst proto
the result was:
classify table: match count required
I've done some research around this error, but I couldn't find anything
helpful. So, I was wondering if there is a manual for this command? or can you
tell me what the problem is? I also tried to enter an integer number as match
and I got this error:
exec error: Misc
thanks.
