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>
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:
• Civic address: physical address data such as city, street number, and building information
• ELIN (Emergency Location Identification Number): an emergency number typically assigned to MLTS
(Multiline Telephone System) Operators in North America
• Coordinate-based location: attitude, longitude, and altitude information (Requires configuration via an SNMP
application.)
Configuring location data for LLDP-MED devices
Syntax:
[no] lldp config <port-list> medPortLocation <Address-Type>
Configures location of emergency call data the switch advertises per port in the location_id TLV. This TLV is
for use by LLDP-MED endpoints employing location-based applications.
