Power Over Ethernet (PoE) Operation

PoE/PoE+ Allocation Using LLDP Information

PoE/PoE+ Allocation Using LLDP InformationLLDP with PoE

When using PoE, enabling poe-lldp-detectallows automatic power configura­ tion if the link partner supports PoE. When LLDP is enabled, the information about the power usage of the PD is available and the switch can then comply with or ignore this information. You can configure PoE on each port according to the PD (IP phone, wireless device, etc.) specified in the LLDP field. The default configuration is for PoE information to be ignored if detected through LLDP.

Detecting PoE information via LLDP only affects power delivery; it does not affect normal Ethernet connectivity.

To enable or disable ports for allocating power using LLDP, use this command.

Syntax: int <port-list> poe-lldp-detect [enabled disabled]

Enables or disables port(s) for allocating PoE power based on the link-partner’s capabilities via LLDP.

Default: Disabled

For example, you can enter this command to enable LLDP detection:

ProCurve(config)# int 7 poe-lldp-detect enabled

or in interface context:

ProCurve(eth-7)# poe-lldp-detect enabled

To enable PoE detection via LLDP TLV advertisement, use this command and insert the desired port or ports:

ProCurve(config)# lldp config <port-number> medTlvenable poe
