Table 13-2 Matching relationship between port types and voice traffic types
Port voice
VLAN mode
Voice traffic
type
Port type Supported or not
Access Not supported
Trunk
Supported
Make sure the default VLAN of the port exists and is not a
voice VLAN. And the access port permits the traffic of the
default VLAN.
Tagged
voice traffic
Hybrid
Supported
Make sure the default VLAN of the port exists and is not a
voice VLAN. The default VLAN must be in the list of the tagged
VLANs whose traffic is permitted by the access port.
Access
Trunk
Automatic
mode
Untagged
voice traffic
Hybrid
Not supported, because the default VLAN of the port must be
a voice VLAN and the access port is in the voice VLAN. This
can be done by adding the port to the voice VLAN manually.
Access Not supported
Trunk
Supported
Make sure the default VLAN of the port exists and is not a
voice VLAN. And the access port permits the traffic of the
default VLAN.
Tagged
voice traffic
Hybrid
Supported
Make sure the default VLAN of the port exists and is in the list
of the tagged VLANs whose traffic is permitted by the access
port.
Access
Supported
Make sure the default VLAN of the port is a voice VLAN.
Trunk
Supported
Make sure the default VLAN of the port is a voice VLAN and
the port permits the traffic of the VLAN.
Manual
mode
Untagged
voice traffic
Hybrid
Supported
Make sure the default VLAN of the port is a voice VLAN and is
in the list of untagged VLANs whose traffic is permitted by the
port.
Security Mode of Voice VLAN
On the WX3000 devices, a voice VLAN can operate in the security mode. Voice VLANs operating in this
mode only permit voice data, enabling you to perform voice traffic-specific priority configuration. With
the security mode disabled, both voice data and service data can be transmitted in a voice VLAN.
Voice VLAN Configuration
Configuration Prerequisites
z
Create the corresponding VLAN before configuring a voice VLAN.
z
VLAN 1 (the default VLAN) cannot be configured as a voice VLAN.
