Step

2. Enable LLDP to automatically
discover IP phones.

Configuring LLDP to advertise a specific voice
VLAN
Voice VLAN advertisement through LLDP is available only for LLDP-enabled IP phones. If
CDP-compatibility is enabled, this feature is also available for CDP-enabled IP phones. For more
information about CDP compatibility, see

Configuration guidelines

By default, if the voice VLAN feature is configured on an LLDP-enabled port, LLDP advertises this voice
VLAN to the IP hone connected to the port. This feature allows you to specify the voice VLAN information
that LLDP will advertise to IP phones through network policy TLVs.
Figure 53 shows the procedure of voice VLAN advertisement through LLDP.
Figure 53 Voice VLAN advertisement through LLDP
With the received voice VLAN information, the IP phone automatically completes the voice VLAN
configuration, including the voice VLAN ID, tagging status, and priority. This voice VLAN can be the
voice VLAN directly specified for LLDP advertisement, the voice VLAN configured on the port, or the voice
VLAN assigned by a server, depending on your configuration.
