In Python 3.5,
STP Application (ryu.app.simple_switch_stp) is not working.
[STP][INFO] dpid=0000000000000002: [port=2] NON_DESIGNATED_PORT / BLOCK
[STP][INFO] dpid=0000000000000002: [port=3] ROOT_PORT / FORWARD
SimpleSwitchStp: Exception occurred during handler processing. Backtrace
from offending handler [packet_in_handler] servicing event [EventPacketIn]
follows.
Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/ryu/base/app_manager.py",
line 290, in _event_loop
handler(ev)
File
"/usr/local/lib/python3.5/dist-packages/ryu/app/simple_switch_stp.py", line
85, in packet_in_handler
dst, src, _eth_type = struct.unpack_from('!6s6sH', buffer(msg.data), 0)
NameError: name 'buffer' is not defined
But in 2.7, it works perfectly.
