Which actions occur when setting the VLAN ID of the port group to 10 in Huawei FusionCompute?

When the VLAN ID of the port group is set to 10 in Huawei FusionCompute, the action that occurs is that untagged data frames are forwarded. In VLAN-configured networks, when a port group is assigned a VLAN ID, it typically follows the rules of that specific VLAN.

In this context, untagged data frames are those that do not have any VLAN tagging, meaning they do not belong to a specific VLAN. When the port group is set to VLAN ID 10, untagged frames can still be associated with that VLAN, and thus they are allowed to pass through without being blocked. This ensures that basic network traffic can still function effectively even if it does not include specific VLAN tagging, which is crucial for maintaining connectivity in environments where not all devices may support VLAN tagging.

In contrast, the other options propose actions that either involve blocking or relabeling packets in ways that do not align with the proper operational behavior of VLAN configurations. For example, relabeling frames or dropping frames that do not fit the designated VLAN ID can create network disruptions, which is not the standard behavior when allowing untagged frames in a VLAN environment.
