Hi, i need some confirmation.. if i captured a port traffic with access or trunk mode, will the vlan id appeared in the outbound direction of an interface in wireshark ? I don't know why my NIC still strip 802.1Q header, i have modify the registry and use the SPAN configuration to captured the vlan id.
Thanks a lot. Really appreciate it.
Thanks Martin, the picture help me a lot. The picture above using configuration of trunk, right ? How about access mode or native vlan ? Will it shown the VLAN ID also?
From what i read, access vlan or native vlan will not shown any vlan id in the frame as it will send as an original frame.
