When configuring a bridging ONU, how do you set the VLAN of the ETH1 port if the ETH1 port is used for a PC to access the Internet?

Show Suggested Answer Hide Answer
Suggested Answer: D

Bridging ONU Configuration :

A bridging ONU acts as a transparent bridge between the PC and the OLT, forwarding traffic without modifying it.

VLAN Configuration for ETH1 :

VLAN 1 : The default VLAN, often reserved for management purposes. Using it for Internet access is not recommended.

Default Configuration : Leaving the port unconfigured may result in improper VLAN tagging or untagged traffic, leading to connectivity issues.

VLAN 4094 : Typically reserved for special purposes (e.g., QinQ termination) and is not suitable for general Internet access.

Native VLAN : Configuring a native VLAN ensures that untagged traffic from the PC is associated with the correct VLAN for Internet access.

Why D?

Configuring a native VLAN is the correct approach to ensure proper VLAN tagging and seamless Internet access for the PC connected to ETH1.

Thus, the correct answer is D .

I think option A is the best choice. VLAN 1 is commonly used for Internet access.

Not so sure about that, what if the PC needs a different VLAN?

Wait, VLAN 4094? Isn't that for special cases?

Definitely not B, that won't work for VLANs.

I think you should configure VLAN 1 on ETH1.

VLAN 4094 sounds familiar, but I thought that was more for special cases. I need to double-check what that actually does.

I’m leaning towards configuring a native VLAN, but I’m not clear on how that affects the traffic for the PC.

I remember something about using the default configuration, but I feel like that might not be secure enough for a PC accessing the Internet.

I think we might need to configure VLAN 1 on ETH1, but I’m not entirely sure if that’s the best practice for Internet access.
