Scenarios

Separate Devices for Independent Room

The following topology diagram describes the deployment and connection. According to the requirements of independent meeting rooms, each meeting room contains camera and audio devices connected to the MCore through the AV hub and a common PoE switch. The equipment in each meeting room is divided into its VLAN managed by a PoE switch.

Combine Camera and Audio Devices into One Room

By changing the configuration of VLAN management only, the camera and audio devices can connect to the MCore through one AV hub. This allows all audio and video devices to be managed by the same MCore, accommodating the requirement of combining two meeting rooms into one. Note that when combining camera and audio devices, we need only one MCore to manage them. Therefore, another MCore connected to port 8 as illustrated in the image below is not required.

Configuration Procedures

Separate Devices for Independent Room

A VLAN is a logical group of ports that enables devices associated with it to communicate with each other over the Ethernet MAC layer, regardless of the physical LAN segment of the bridged network to which they are connected.

When using the factory default settings, the switch automatically creates VLAN1 as the default VLAN. Take the Cisco switch as an example; all ports’ default interface status is Trunk, and all ports of the default VLAN are configured as untagged members.

A port in VLAN Access mode can be part of only one VLAN. If it is in General or Trunk mode, the port can be part of one or more VLANs.

If there is no VLAN tag in the frame, the frame is classified as the VLAN based on the Port VLAN Identifier (PVID) configured at the ingress port where the frame is received. Frames belonging to a VLAN remain within the VLAN. This is achieved by sending or forwarding a frame only to egress ports that are members of the target VLAN.

An egress port may be configured as a tagged or untagged member of a VLAN. Remove the VLAN tag from the frame if the egress port is configured as an untagged member of the target VLAN.

When the audio and video devices of the Microsoft Teams meeting system in two meeting rooms are connected by a switch, we have to make sure they are separated by two VLANs, such as the configuration list of the switch listed below.

Procedure:

1.         Create new VLANs and attach the ports to the corresponding VLAN.

1. Create two new VLANs,  with one VLAN identifier as 2 and the other as 3 respectively.
2. Attach ports 1-4 to the  VLAN 2 and ports 5-8 to the VLAN 3.

2.        Remove the VLAN membership of the ports 1-8 from the original default VLAN 1.

3.         Change the PVID of ports 1-4 to 2 and the PVID of ports 5-8 to 3.

4.        Change the tagged member of ports 1-8 as untagged.

If you have trouble configuring the ports and VLAN, please feel free to contact Yealink technical support.

Combine Camera and Audio Devices into One Room

When the two kits of MTR devices are required to combine into one system, we only need to change the configuration of the switch, then the audio and video devices can attach to one single AV hub.

The following table lists the configuration of the switch.

Procedure:

1.         Attach ports 5-7 to the VLAN 2.

2.        Remove VLAN membership of ports 5-7 from the original VLAN 3.

3.         Change the PVID of ports 5-7 to 2.

If you have trouble configuring the ports and VLAN, please feel free to contact Yealink technical support.
