Configuration Procedure; Configuring Lldp To Advertise A Specific Voice Vlan; Configuration Guidelines - HP 6125G Configuration Manual

Globally enable LLDP.
•
• Enable LLDP on the port connecting to an IP phone and configure the port to operate in TxRx mode.

Configuration procedure

CAUTION:
The maximum TTL value that CDP allows is 255 seconds. To make CDP-compatible LLDP work properly
with Cisco IP phones, be sure that the product of the TTL multiplier and the LLDPDU transmit interval is less
than 255 seconds.
CDP-compatible LLDP operates in one of the follows modes:
TxRx—CDP packets can be transmitted and received.
•
Disable—CDP packets cannot be transmitted or received.
•
To make CDP-compatible LLDP take effect on specific ports, first enable CDP-compatible LLDP globally,
and then configure CDP-compatible LLDP to operate in TxRx mode.
To enable LLDP to be compatible with CDP:
Step
1. Enter system view.
2. Enable CDP compatibility
globally.
3. Enter Layer 2 Ethernet
interface view.
4. Configure CDP-compatible
LLDP to operate in TxRx
mode.
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
the voice VLANs, 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 67 shows the procedure of voice VLAN advertisement through LLDP.
