![]() ![]() Your overview will look like this: The VLANs are now configured but we still have to assign our interfaces to the correct VLAN.Select VLAN Management and then Interface Settings: You will see the following overview with all interfaces on the switch. ![]() So I think you can resolve your problem and avoid having to update your version of libpcap if you rewrite your capture filter without using the vlan primitive. Hit the Create VLAN button: Add VLAN 2,3 and 4 and give it a descriptive name. ![]() Here is a technique that can be used to capture the dot1q header on. Filtering: Wireshark is capable of slicing and dicing all of this random live data using filters. In some cases changes need to be made to the registry to enable display of VLAN tagging.

Like any other packet sniffer, Wireshark does three things: Packet Capture: Wireshark listens to a network connection in real time and then grabs entire streams of traffic quite possibly tens of thousands of packets at a time. Each use of that expression increments the filter offsets by 4.įilters on VLAN 200 encapsulated within VLAN 100, andįilters IPv4 protocols encapsulated in VLAN 300 encapsulated within any higher order VLAN. have someone managed to capture packets vlan info with Wireshark. The vlan expression may be used more than once, to filter on VLAN hierarchies. Note that the first vlan keyword encountered in expression changes the decoding offsets for the remainder of expression on the assumption that the packet is a VLAN packet. If is specified, only true if the packet has the specified vlan_id. The phisical interface from proxmox included in the virtual bridge (vmbr0) created with proxmox.Includes tagging. True if the packet is an IEEE 802.1Q VLAN packet. Therefore, port 4 requires untagged traffic to provide connectivity to the real machine, the Proxmox itself and requires Mikrotik being able to route and firewall the packets from tag 100 and 200. While your version of libpcap (1.5.3) seems to be buggy, I think the problem is with the vlan primitive and the mistake of not dealing with its affect on offsets.
