Hello,

I am research student in IIT Madras, interested doing some research work in
P4. With current P4 capabilities I want to know how to debug the P4 program
for V1model switch.

I suppose "error class" and verify() is not present for v1model, if so, are
there any ways to debug the P4 program for v1model. (i.e, how to know my
packet is parsed successfully, what header values it is picking etc?).
Please help me on this.

Thank you,
Phani
