location_id
This TLV enables the switch port to advertise its configured location data (if any). For
more information on configuring location data, see Configuring location data for
LLDP-MED devices on page 193.(Default: Enabled)
When disabled, this TLV cannot be enabled unless the capability TLV is already
enabled.
poe
This TLV enables the switch port to advertise its current PoE state and to read the
PoE requirements advertised by the LLDP-MED endpoint device connected to the
port.(Default: Enabled)
When disabled, this TLV cannot be enabled unless the capability TLV is already
enabled.
For more on this topic, see PoE advertisements on page 192.
PoE advertisements
These advertisements inform an LLDP-MED endpoint of the power (PoE) configuration on switch ports. Similar
advertisements from an LLDP-MED endpoint inform the switch of the endpoint's power needs and provide
information that can be used to identify power priority mismatches.
PoE TLVs include the following power data:
• Power type: indicates whether the device is a power-sourcing entity (PSE) or a PD. Ports on the J8702A PoE
zl module are PSE devices. A MED-capable VoIP telephone is a PD.
• Power source: indicates the source of power in use by the device. Power sources for PDs include PSE, local
(internal), and PSE/local. The switches advertise Unknown.
• Power priority: indicates the power priority configured on the switch (PSE) port or the power priority
configured on the MED-capable endpoint.
• Power value: indicates the total power in watts that a switch port (PSE) can deliver at a particular time, or the
total power in watts that the MED endpoint (PD) requires to operate.
Viewing PoE advertisements
To display the current power data for an LLDP-MED device connected to a port, use the following command:
show lldp info remote-device <port-list>
For more information on this command, see page A-60.
To display the current PoE configuration on the switch, use the following commands:
show power brief <port-list>
show power <port-list>
For more information on PoE configuration and operation, see
Power Over Ethernet (PoE/PoE+) Operation.
Location data for LLDP-MED devices
You can configure a switch port to advertise location data for the switch itself, the physical wall-jack location of the
endpoint (recommended), or the location of a DHCP server supporting the switch, endpoint, or both. You also
have the option of configuring these different address types:
