Configuration Procedure; Dynamically Advertising Server-Assigned Vlans Through Lldp - HP 6125G Configuration Manual

Figure 67 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.
To identify the voice VLAN advertised by LLDP, execute the display lldp local-information command, and
examine the MED information fields in the command output.

Configuration procedure

To configure LLDP to advertise a specific voice VLAN:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view.
3. Configure LLDP to advertise a
specific voice VLAN.
Dynamically advertising server-assigned VLANs
through LLDP
Dynamic advertisement of server-assigned VLANs through LLDP must work with 802.1X or MAC
authentication, and is available only for LLDP-enabled IP phones. If 802.1X authentication is used, make
sure the IP phones also support 802.1X authentication.
To implement this function for an IP phone, perform the following configuration tasks:
Enable LLDP globally and on the port connected to the IP phone.
•
Configure 802.1X or MAC authentication to make sure the IP phone can pass security
•
authentication. For more information about 802.1X authentication, MAC authentication, and VLAN
assignment by servers, see Security Configuration Guide.
Configure VLAN authorization for the IP phone on the authentication server.
