• Transmit TLVs -
Policies
When checked the configured policies for the interface is included
in LLDP-MED information transmitted.
• Transmit TLVs -
Location
When checked the configured location information for the switch is included
in LLDP-MEDinformation transmitted.
• Device Type
Any LLDP-MED Device is operating as a specific type of LLDP-MED Device,
which may be either a Network Connectivity Device or a specific Class of
Endpoint Device, as defined below.
A Network Connectivity Device is a LLDP-MED Device that provides access to
the IEEE 802 based LAN infrastructure for LLDP-MED Endpoint Devices
An LLDP-MED Network Connectivity Device is a LAN access device based on
any of the following technologies :
1. LAN Switch/Router
2. IEEE 802.1 Bridge
3. IEEE 802.3 Repeater (included for historical reasons)
4. IEEE 802.11 Wireless Access Point
5. Any device that supports the IEEE 802.1AB and MED extensions that can
relay IEEE 802 frames via any method.
An Endpoint Device a LLDP-MED Device that sits at the network edge and
provides some aspect of IP communications service, based on IEEE 802 LAN
technology.
The main difference between a Network Connectivity Device and an Endpoint
Device is that only an Endpoint Device can start the LLDP-MED information
exchange.
Even though a switch always should be a Network Connectivity Device, it is
possible to configure it to act as an Endpoint Device, and thereby start the
LLDP-MED information exchange (In the case where two Network Connectivity
Devices are connected together)

• Latitude
Latitude SHOULD be normalized to within 0-90 degrees with a maximum of 4
digits.
It is possible to specify the direction to either North of the equator or South of the
equator.
• Longitude
Longitude SHOULD be normalized to within 0-180 degrees with a maximum of 4
digits.
It is possible to specify the direction to either East of the prime meridian or West
