As per section 10.2.4.4 of the LLDP-MED standard, LLDP-MED endpoint devices
need to transmit Location Identification TLVs if they are capable of either
automatically determining their physical location by use of GPS or radio beacon or
capable of being statically configured with this information.
At present, the SoundPoint IP / SoundStation IP / VVX phones do not have the
capability to determine their physical location automatically or provision to a
statically configured location. Because of these limitations, the SoundPoint IP /
SoundStation IP / VVX phones will not transmit Location Identification TLV in the
LLDP frame. However, the location information from the switch is decoded and
displayed on the phone's menu.
For more information on configuration parameters, refer to
Configuration on page A-157.
This is the basic TLV format:
TLV Type (7 bits) [0-6]
