3.8.8 (Optional) Configuring a Port to Communicate with a Voice
Device of Another Vendor
The voice VLAN legacy function can be configured to allow Huawei datacom devices to identify
packets of proprietary protocols of other vendors.
Context
After VoIP devices of some vendors are powered on, proprietary protocol packets but not DHCP
packets are sent to apply for IP addresses. To help Huawei datacom devices communicate with
voice devices of other vendors, you can enable the voice VLAN legacy function. This allows
Huawei devices to identify packets of proprietary protocols of other vendors.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The view of a port connecting the device to users' voice devices is displayed.
Step 3 Run:
voice-vlan legacy enable
The port is configured to communicate with a voice device of another vendor.
By default, ports on Huawei devices cannot communicate with voice devices of other vendors.
----End
3.8.9 Checking the Configuration
After a voice VLAN is configured, you can view information about the voice VLAN, including
the OUI, working mode, security mode or ordinary mode, aging timer value, the 802.1p priority
and DSCP value as well as the configuration of the port enabled with the voice VLAN function.
Prerequisite
The configurations of a voice VLAN are complete.
