Huawei Hybrid Port: Which VLANs Have Tags Removed?
Short answer
A VLANs 1, 4, and 6 are on the Hybrid interface's untagged list, so the switch removes their VLAN tags before forwarding frames.
Question
Key Takeaways
It tests the tagged-versus-untagged boundary on a Hybrid port, and the main trap is forgetting that VLAN 1 remains untagged by default even when only VLANs 4 and 6 are explicitly configured.
This H12-811 question tests Huawei Hybrid interface tag handling: the switch removes a VLAN tag only for VLANs in the port's untagged list. The correct answer is A (VLANs 1, 4, and 6).
Common mistake: Choosing B (4, 6) because the displayed `port hybrid untagged vlan 4 6` command names only those VLANs; this ignores the default untagged state of VLAN 1.
Expert Analysis
The boundary to test: tagged vs. untagged
This H12-811 item is not asking which VLANs the Hybrid port “belongs to.” It asks which VLANs are on the egress untagged side of the port’s Hybrid configuration. On Huawei switches, port hybrid tagged vlan … keeps the 802.1Q tag, while port hybrid untagged vlan … strips it before forwarding. The exhibit places VLAN 5 in the tagged list and VLANs 4 and 6 in the untagged list, so 5 is immediately excluded; options C and D both contain 5 and cannot be correct.
Why VLAN 1 remains in the answer
The narrow trap is treating the displayed commands as a complete replacement list. A Huawei Hybrid port starts with VLAN 1 untagged by default, and port hybrid untagged vlan 4 6 adds 4 and 6 rather than deleting 1. The supplied comment makes this point: VLAN 1 stays untagged unless it is explicitly removed or its default behavior is changed. Therefore the interface removes tags for VLANs 1, 4, and 6, which is option A. Option B is the attractive distractor because it copies only the explicitly typed untagged VLANs and ignores the default.
Exam Strategy
For Hybrid-port questions, translate each command into egress behavior before comparing options: tagged means keep the tag, untagged means strip it. Then look for defaults omitted from display current-configuration, especially VLAN 1 and the PVID. If two options differ only by VLAN 1, the default is likely the intended discriminator; if any option includes a VLAN from the tagged list, eliminate it immediately.
Frequently Asked Questions
Why is VLAN 1 untagged even though it is not shown in the Hybrid port commands?
port hybrid untagged vlan 4 6 adds VLANs rather than replacing the list. VLAN 1 is removed only with an explicit undo or change.Does `port hybrid tagged vlan 5` remove VLAN 5's tag before forwarding?
tagged keyword means frames for VLAN 5 leave the port with their 802.1Q tag intact; only the untagged list causes tag removal.How does the PVID relate to the untagged VLAN list on a Hybrid port?

Even if the configuration only shows VLAN 4 and 6 as untagged, VLAN 1 remains in the untagged VLAN list unless it is explicitly removed or changed. Therefore, the interface removes tags for: ✅ VLAN 1, 4, and 6 → Answer A.
