Power Over Ethernet (PoE) Operation
PoE/PoE+ Allocation Using LLDP Information
PoE/PoE+ Allocation Using LLDP
Information
LLDP with PoE
When using PoE, enabling
poe-lldp-detect
allows 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.
N o t e
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>
