虛擬局域網（0x8100）支持dpkt python

我有一個數據包顯示是一種類型的vlan。我正在使用dpkt 1.6版本來提取字段。但是，似乎不支持vlan類型。當條件爲虛擬局域網（0x8100）支持dpkt python

eth = dpkt.ethernet.Ethernet(header_sampled_packet) 
print eth.type

應用它顯示類型爲0x0800的是IP類型，但它實際上必須0X8100。

在dpkt中不支持VLAN嗎？或支持更高版本。如何通過dpkt提取字段或者是否有其他包？。

我有十六進制與VLAN數據流，這是sFlow的十六進制數據

這個問題很難追蹤沒有任何數據。請添加您認爲被錯誤解釋的數據包的十六進制轉儲。 –

@KlausD。在dpkt中支持vlan嗎？ –

我正在使用dpkt 1.6 –

步入dptk.ethernet.py文件後，我發現，高清_unpack_data（個體經營，BUF）：被拉出VLAN信息已經。

if self.type == ETH_TYPE_8021Q: 
    self.tag, self.type = struct.unpack('>HH', buf[:4]) 
    buf = buf[4:]

我不擅長dpkt但我認爲self.tag是VLAN ID和類型是self.data

在我的代碼我這樣做的類型：

for ts, buf in pcap: 
    try: 
     eth = dpkt.ethernet.Ethernet(buf) 
     ip = eth.data 
     if eth.type == dpkt.ethernet.ETH_TYPE_PPPoE_DISC or eth.type == dpkt.ethernet.ETH_TYPE_PPPoE: 
      ip = dpkt.pppoe.PPPoE(eth.data) 
     if hasattr(eth, 'tag'): 
      print("eth tag = %s" %(eth.tag)) 
    except Exception as dpkterr: 
     print("Dpkt exception: %s" %(dpkterr))

這似乎工作。
