[pox-dev] [TCP-OPT ISSUE]

[Marcus Sandri]

Exactly,


But how can I access .val atributes?
 I tried:

packet = event.parsed
packet_tcp = packet.find("tcp")
if(packet_tcp):

            tcp_raw = tcp_opt.val


But it returns: line 29, in _handle_PacketIn
tcp_options = tcp_opt.val
AttributeError: class tcp_opt has no attribute 'val'

It works with the tcp_opt constants, such as: EOL, SACK, etc.

Am I doing something wrong?
