Hi, All:
I use the following code to traversing packet header:
for p in pkt.protocols:
print p.protocol_name
The error show:
AttributeError: 'str' object has no attribute 'protocol_name'
So i debug this pakcet:
to quagga pkt:
ethernet(dst='e6:59:e2:8f:87:f3',ethertype=33024,src='04:8d:7b:fc:16:11'),
vlan(cfi=0,ethertype=2054,pcp=0,vid=101),
arp(dst_ip='20.1.1.2',dst_mac='e6:59:e2:8f:87:f3',hlen=6,hwtype=1,opcode=2,plen=4,proto=2048,src_ip='20.1.1.1',src_mac='04:8d:7b:fc:16:11'),
'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'
p:ethernet(dst='e6:59:e2:8f:87:f2',ethertype=33024,src='04:7d:7b:fc:16:11')
p:vlan(cfi=0,ethertype=2054,pcp=0,vid=101)
p:arp(dst_ip='20.1.1.2',dst_mac='e6:59:e2:8f:87:f2',hlen=6,hwtype=1,opcode=2,plen=4,proto=2048,src_ip='20.1.1.1',src_mac='04:7d:7b:fc:16:11')
p:'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'
The error happend when the 'p' point to
'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00'
which is the data but not head in the packet.
I think it maybe a bug in the ryu3.23, but if not, what is the correct way
to traversing packet header
Thankyou
