たとえば、このパケットがある場合など、複数の vlan がある場合、どうすれば vlan のリストを取得できますか..

Layer ETH:
    Destination: 00:99:88:77:66:55 (00:99:88:77:66:55)
    .... ..0. .... .... .... .... = LG bit: Globally unique address (factory default)
    Address: 00:99:88:77:66:55 (00:99:88:77:66:55)
    .... ...0 .... .... .... .... = IG bit: Individual address (unicast)
    Type: 802.1Q Virtual LAN (0x8100)
    Source: 00:11:22:33:44:55 (00:11:22:33:44:55)
    .... ..0. .... .... .... .... = LG bit: Globally unique address (factory default)
    Address: 00:11:22:33:44:55 (00:11:22:33:44:55)
    .... ...0 .... .... .... .... = IG bit: Individual address (unicast)
Layer VLAN:
    ...0 .... .... .... = CFI: Canonical (0)
    000. .... .... .... = Priority: Best Effort (default) (0)
    .... 0000 1100 1000 = ID: 200
    Type: 802.1Q Virtual LAN (0x8100)
Layer VLAN:
    Trailer: 8dbdde29
    ...0 .... .... .... = CFI: Canonical (0)
    000. .... .... .... = Priority: Best Effort (default) (0)
    .... 0000 0110 0100 = ID: 100
    Type: IP (0x0800)
Layer IP:
    ....
Layer UDP:
    ....

pyshark を使用すると、内部 VLAN しか取得できません。

>>> print cap[0]['vlan']
Layer VLAN:
    ...0 .... .... .... = CFI: Canonical (0)
    000. .... .... .... = Priority: Best Effort (default) (0)
    .... 0000 1100 1000 = ID: 200
    Type: 802.1Q Virtual LAN (0x8100)

私はそれが tshark と同じになることを期待しています:

tshark -r filename.pcap -T fields -e vlan.id

100,200

ダブル VLAN を取得する簡単な方法は次のとおりです。

vlan1, vlan2 = pkt[1], pkt[2]

または明示的に：

vlan1, vlan2 = pkt.layers[1], pkt.layers[2]
