NEW QUESTION # 309
Refer to the following VLAN configurations on a Huawei switch. Which of the following statements are true?
Answer: B,C,D
Explanation:
To determine which statements are true, we need to analyze the VLAN configurations on the Huawei switch (SWA) as shown in the diagram and configuration details. We'll evaluate each client's VLAN membership and verify the correctness of the VLAN assignment commands based on Huawei switch configuration principles, as outlined in HCIA Datacom documentation. Let's break it down step by step:
* Understanding VLAN Assignment Types on Huawei Switches:
* Huawei switches support different port link types for VLAN assignment:
* Access Port: Carries traffic for a single VLAN (untagged). Typically used for end devices like PCs.
* Trunk Port: Carries traffic for multiple VLANs (tagged, except for the native VLAN, which is untagged). Typically used for interconnecting switches.
* Hybrid Port: Similar to a trunk port but can carry untagged traffic for specific VLANs, often used for both end devices and inter-switch links. It can tag or untag traffic based on configuration.
* Additionally, Huawei supports MAC address-based VLAN assignment (using the mac-vlan command), which assigns VLAN membership based on a device's MAC address, overriding port- based VLAN settings.
* Analyzing the Configuration for Each Client:Let's examine the configuration details for each interface connected to the clients and verify the VLAN assignments:
* Client 1 (connected to GigabitEthernet0/0/1):
* Configuration:
text
WrapCopy
vlan 10
#
interface GigabitEthernet0/0/1
port link-type access
port default vlan 10
* The port is configured as an access port with port link-type access and assigned to VLAN
10 using port default vlan 10.
* Access ports carry untagged traffic for a single VLAN, so Client 1 belongs to VLAN 10.
* The commands are correct for an access port assignment to VLAN 10.
* Statement C ("Client 1 belongs to VLAN 10, and the commands for VLAN assignment on the switch are correct") is true.
* Client 2 (connected to GigabitEthernet0/0/2):
* Configuration:
text
WrapCopy
vlan 20
mac-vlan mac-address 0022-0022-0022 priority 0
#
interface GigabitEthernet0/0/2
port hybrid untagged vlan 20
mac-vlan enable
* The port is configured as a hybrid port with port link-type hybrid and set to carry untagged traffic for VLAN 20 using port hybrid untagged vlan 20.
* Additionally, mac-vlan mac-address 0022-0022-0022 priority 0 and mac-vlan enable are configured, indicating MAC address-based VLAN assignment for a device with MAC address 0022-0022-0022.
* However, the diagram does not specify the MAC address of Client 2. If Client 2's MAC address is not 0022-0022-0022, the MAC-VLAN assignment does not apply, and the port's default VLAN (VLAN 20, untagged) determines its membership.
* If Client 2 has MAC address 0022-0022-0022, it would belong to the VLAN specified by the mac-vlan command (VLAN 20, as no specific VLAN is mentioned in the mac-vlan command, implying it uses the port's default VLAN or another configured VLAN). But since the MAC address is not provided, we assume the port-based VLAN assignment (VLAN 20) applies.
* The commands appear correct for a hybrid port with untagged VLAN 20 and MAC-VLAN enabled, but the effectiveness of the MAC-VLAN depends on Client 2's MAC address.
* Statement B ("Client 2 belongs to VLAN 20, and the commands for MAC address-based VLAN assignment on the switch are correct") is potentially true if Client 2's MAC is 0022-
0022-0022, but without confirmation, we must consider the port's default VLAN 20.
However, the MAC-VLAN priority is set to 0, which is unusual (priority 0 typically indicates the lowest priority, and Huawei recommends non-zero values for MAC-VLAN).
This suggests a potential configuration error or ambiguity.
* Given the lack of MAC address confirmation and the unusual priority 0, Statement B is not definitively true, as the MAC-VLAN assignment may not function as intended or may conflict with port-based VLAN 20.
* Client 3 (connected to GigabitEthernet0/0/3):
* Configuration:
text
WrapCopy
vlan 30
#
interface GigabitEthernet0/0/3
port link-type trunk
port trunk allow-pass vlan 30
* The port is configured as a trunk port with port link-type trunk and allows VLAN 30 traffic using port trunk allow-pass vlan 30.
* Trunk ports carry tagged traffic for specified VLANs. For Client 3 (an end device, typically not a switch), the trunk port configuration is unusual because end devices usually connect via access ports, not trunk ports. However, if Client 3 is configured to send tagged frames for VLAN 30 (e.g., a VLAN-aware device like a phone or IP camera), it can belong to VLAN 30.
* The commands are correct for a trunk port allowing VLAN 30, assuming Client 3 is configured to handle tagged VLAN 30 traffic.
* Statement D ("Client 3 belongs to VLAN 30, and the commands for VLAN assignment on the switch are correct") is true, assuming Client 3 supports VLAN tagging for VLAN 30.
* Client 4 (connected to GigabitEthernet0/0/4):
* Configuration:
text
WrapCopy
vlan 40
#
interface GigabitEthernet0/0/4
port link-type hybrid
port hybrid untagged vlan 40
* The port is configured as a hybrid port with port link-type hybrid and set to carry untagged traffic for VLAN 40 using port hybrid untagged vlan 40.
* Hybrid ports can carry untagged traffic for specific VLANs, so Client 4 belongs to VLAN
40 (untagged).
* The commands are correct for a hybrid port assignment to VLAN 40.
* Statement A ("Client 4 belongs to VLAN 40, and the commands for VLAN assignment on the switch are correct") is true.
* Evaluating Each Statement:
* A: True - Client 4 belongs to VLAN 40 (untagged on a hybrid port), and the commands are correct.
* B: Not definitively true - Client 2 belongs to VLAN 20 based on the port's hybrid untagged VLAN 20, but the MAC-VLAN configuration with priority 0 is ambiguous without Client 2's MAC address, and the priority 0 may indicate a configuration error. Thus, we cannot confirm the MAC address-based VLAN assignment is correct.
* C: True - Client 1 belongs to VLAN 10 (access port), and the commands are correct.
* D: True - Client 3 belongs to VLAN 30 (trunk port, assuming tagged traffic), and the commands are correct for a trunk port allowing VLAN 30.
* Conclusion:
* Statements A, C, and D are true based on the configuration and VLAN assignment rules.
Statement B is not definitively true due to the ambiguity of Client 2's MAC address and the unusual priority 0 in the MAC-VLAN configuration.
