hi kids, this is your dad, huahuanjayy wkwkwk, Nuenomaru the handsome is back in action.
Okay, this time your dad is going to write a tutorial Voice VLAN Configuration on Ruijie Cloud. Ever plugged in an IP phone and suddenly felt like the network was speaking a completely different language? Don’t worry your switches are not haunted, and your VoIP phones are not being dramatic.
In this tutorial, we’ll walk through how to configure Voice VLAN on Ruijie Cloud, so your voice traffic can travel smoothly, clearly, and without fighting your regular data traffic for attention. Think of it as giving your phone calls their own VIP lane on the network highway.
So grab your coffee, open your dashboard, and let’s make your VoIP setup sound as professional as it should.
Voice Vlan introduction:
- In enterprise office networks, VoIP services have high requirements for communication quality. By configuring a Voice VLAN, the delay of VoIP services can be reduced and the quality of voice calls can be improved.
- This course primarily covers the use cases and functions of Voice VLAN, key configuration methods, and important considerations.
- IP phones are widely used in scenarios such as offices and medical institutions. They can facilitate internal communication within enterprises and enhance the security of internal information transmission.
- VoIP has high requirements for network bandwidth, latency, and stability. To ensure the quality of VoIP services, it is often necessary to use QoS (Quality of Service) related technologies to elevate the priority of VoIP traffic and guarantee voice quality.
- Voice VLAN function for switch has 2 mode, Automatic Mode and Manual Mode.
- Automatic Mode is suitable for the scenario where IP phones are connected to PCs through ports. In this situation, IP phones need to transmit both Voice data and Network data.
- The precondition of using the automatic mode is that IP phones must support the LLDP protocol.
- Voice VLAN function for switch has 2 mode, Automatic Mode and Manual Mode.
- Manual Mode is suitable for the scenario where IP phones are connected to the switch only and transmit only voice packets. In such networking, the port only transmits voice data, avoiding the influence of service data on the voice data.
Voice Vlan in Cloud:
- Voice VLAN configuration path: Project > Configuration > Device Config > Switch > Voice VLAN
- In the current version, Ruijie Cloud only supports Voice VLAN configuration for Reyee devices.
Step 1: Voice VLAN settings
- Switch: Voice VLAN Function Switch
- VLAN: Designate a specific VLAN as the Voice VLAN
- COS Priority: The QoS priority for the Voice VLAN has a default value of 6, with higher numbers indicating higher priority.
Step 2: Switch Interface Configuration
- Select the interface for which you want to enable the Voice VLAN function, and click 'Edit' to configure it.
- Click 'Batch Edit' to configure the Voice VLAN for multiple interfaces simultaneously.
- Enabled：Enable the Voice VLAN function for this interface.
- Voice VLAN Mode: Set the mode for this interface. Auto Mode is suitable for switch interfaces where multiple types of traffic need to pass through; Manual Mode is suitable for switch interfaces where only voice traffic passes through.
- Security Mode: Enabling this feature can isolate voice traffic from data traffic, preventing malicious attackers from using the Voice VLAN to transmit non-voice data.
Step 3: OUI
- For IP phones that support the LLDP protocol, the switch will collect the OUI information of the device based on the received LLDP messages and encapsulate the voice traffic using the Voice VLAN.
- For IP phones that do not support LLDP, voice traffic needs to be identified by manually adding OUI information.
And that’s it your Voice VLAN is now ready to work like a polite traffic officer, keeping voice calls smooth while the rest of the network does its own thing. No more choppy calls, robotic voices, or people asking, ‘Hello? Can you hear me now?’ every five seconds.
Hopefully your network is now happier, your phones are calmer, and your troubleshooting time is much shorter. Where we’ll probably convince another switch to behave properly.
Hahaha alright, that’s a wrap for today’s article—my coffee’s gone, so that’s my cue to stop typing.
Let’s end this with a Bismillah at the start and an Alhamdulillah at the finish. Catch you next time, tech gembelers!.
