NOTE:
A protocol-based VLAN on a hybrid port can process only untagged inbound packets, whereas the
voice VLAN in automatic mode on a hybrid port can process only tagged voice traffic. Do not
configure a VLAN as both a protocol-based VLAN and a voice VLAN. For more information, see the
chapter ―VLAN configuration.‖
Configuring a port to operate in manual voice VLAN
assignment mode
Follow these steps to set a port to operate in manual voice VLAN assignment mode:
Enable the voice VLAN security
mode
voice vlan security enable
Optional
Enabled by default.
Add a recognizable OUI address
voice vlan mac-address oui mask
oui-mask [ description text ]
Optional
By default, each voice VLAN has
default OUI addresses configured.
For the default OUI addresses of
different vendors, see Table 14.
interface interface-type interface-
number
Configure the port to operate in
manual voice VLAN assignment
mode
undo voice vlan mode auto
Required
Disabled by default
Assign the port (access, trunk, or
hybrid) in manual voice VLAN
assignment mode to the voice
VLAN
For how to assign a port to a
VLAN, see the chapter ―VLAN
configuration.‖
Required
After you assign an access port to
the voice VLAN, the voice VLAN
becomes the PVID of the port
automatically.
Configure the voice VLAN as the
PVID of the port (trunk or hybrid)
For how to assign a port to a
VLAN, see the chapter ―VLAN
configuration.‖
Optional
This operation is required for
untagged inbound voice traffic
and prohibited for tagged
inbound voice traffic.
Enable voice VLAN on the port
voice vlan vlan-id enable
NOTE:
You can configure different voice VLANs on different ports at the same time. However, you can configure one
port with only one voice VLAN, and this voice VLAN must be a static VLAN that already exists on the device.
You cannot enable voice VLAN on a port where Link Aggregation Control Protocol (LACP) is enabled.
To make voice VLAN take effect on a port that is enabled with voice VLAN and operates in manual voice VLAN
assignment mode, you must assign the port to the voice VLAN manually.
