VLAN Tag VLAN Untag VLAN Replace or VLAN Stripping in Network Packet Broker and Network Tap
The interface adds or deletes VLAN tags from the Ethernet data frames it sends and receives, depending on the interface type of the interface and the default VLAN.
Comparison of different types of interfaces for adding or stripping VLAN tags:
|
HOW EACH TYPE OF INTERFACE HANDLES DATA FRAMES? |
|||
|---|---|---|---|
|
Interface Type |
Rx Message without Tag Process |
Rx Message with Tag Process |
Tx Frame Process |
| Access Interface | Receive the message and type the default VLAN ID |
• Receive the message when the VLAN ID is the same as the default VLAN ID. • discard the text when the VLAN ID is different from the default VLAN ID. |
First strip the PVID Tag of the frame and then send it. |
| Trunk Interface |
• type the default VLAN ID and receive the message when the default VLAN ID is in the list of VLAN ids that are allowed to pass. • type the default VLAN ID and discard the text when the default VLAN ID is not in the list of VLAN ids that are allowed to pass. |
• receive the text when the VLAN ID is in the list of VLAN ids that the interface allows to pass. • discard the text when the VLAN ID is not in the list of VLAN ids that the interface allows to pass through. |
• when the VLAN ID is the same as the default VLAN ID and is the VLAN ID allowed by the interface, remove the Tag and send the message. • when the VLAN ID is different from the default VLAN ID and is the VLAN ID allowed by the interface, keep the original Tag and send the message. |
| Hybrid Interface |
• type the default VLAN ID and receive the message when the default VLAN ID is in the list of VLAN ids that are allowed to pass. • type the default VLAN ID and discard the text when the default VLAN ID is not in the list of VLAN ids that are allowed to pass. |
• receive the text when the VLAN ID is in the list of VLAN ids that the interface allows to pass. • discard the text when the VLAN ID is not in the list of VLAN ids that the interface allows to pass through. |
The message is sent when the VLAN ID is the VLAN ID that the interface allows to pass through. You can use commands to set whether to send with a Tag or not. |
The processing process of adding or stripping VLAN tags from the above interfaces can be seen:
1- when receiving data frames without VLAN tags, the Access interface, Trunk interface and Hybrid interface will all label the data frames with VLAN tags. However, the Access interface and Hybrid interface will judge whether the vids of the data frames are allowed to pass through the VLAN, while the Access interface will receive them unconditionally.
2- when receiving a data frame with a VLAN tag, the Access interface, Trunk interface, and Hybrid interface will determine whether to receive the data frame based on whether the VID of the data frame is the VLAN it is allowed to pass through (the VLAN that the Access interface is allowed to pass through is the default VLAN).
3- when sending data frames:
- The Access interface strips the VLAN tag directly from the data frame.
- The Trunk interface will strip VLAN tags from the data frame only if the VID in the data frame is equal to the PVID of the interface.
- The -hybrid interface determines whether to strip the VLAN tag from the data frame based on the configuration on the interface.
Therefore, the data frames sent by the Access interface definitely do not have tags. For the data frames sent by the Trunk interface, only one VLAN data frame does not have tags, while the others all have VLAN tags. For the data frames sent by Hybrid interface, some VLAN data frames can be set with tags, while some VLAN data frames do not have tags.
Several Commonly Used Packet Forwarding Mechanisms during VLAN Tags adding or stripping:
1- Process Switching
2- Fast Switching
3- Cisco Express Forwarding short as CEF
4- Optimum and Distributed Switching
5- Netflow Switching
