Device   (Class   III)   will   also   support   all   aspects   of   TIA-­‐1057   applicable   to   both   Media   Endpoints   (Class   
II)   and   Generic   Endpoints   (Class   I).   

 

LLDP-­‐MED   Generic   Endpoint   (Class   I):   

The    LLDP-­‐MED    Generic    Endpoint    (Class    I)    definition    is    applicable    to    all    endpoint    products    that   
require   the   base   LLDP   discovery   services   defined   in   TIA-­‐1057,   but   do   not   support   IP   media   or   act   as   
an    end-­‐user    communication    appliance.    Such    devices    may    include    (but    are    not    limited    to)    IP   
Communication    Controllers,    other    communication    related    servers,    or    any    device    requiring    basic   

services   as   defined   in   TIA-­‐1057.   

Discovery   services   defined   in   this   class   include   LAN   configuration,   device   location,   network   policy,   
power   management,   and   inventory   management.   

 

LLDP-­‐MED   Media   Endpoint   (Class   II):   

The   LLDP-­‐MED   Media   Endpoint   (Class   II)   definition   is   applicable   to   all   endpoint   products   that   have   
IP    media    capabilities    but    may    or    may    not    be    associated    with    a    particular    end    user.    Capabilities   
include    all    of    the    capabilities    defined    for    the    previous    Generic    Endpoint    Class    (Class    I),    and    are   

extended   to   include   aspects   related   to   media   streaming.   Example   product   categories   expected   to   
adhere   to   this   class   include   (but   are   not   limited   to)   Voice   /   Media   Gateways,   Conference   Bridges,   
Media   Servers,   and   similar.   

Discovery   services   defined   in   this   class   include   media-­‐type-­‐specific   network   layer   policy   discovery.   

 

LLDP-­‐MED   Communication   Endpoint   (Class   III)   :   

The   LLDP-­‐MED   Communication   Endpoint   (Class   III)   definition   is   applicable   to   all   endpoint   products   
that   act   as   end   user   communication   appliances   supporting   IP   media.   Capabilities   include   all   of   the   
capabilities   defined   for   the   previous   Generic   Endpoint   (Class   I)   and   Media   Endpoint   (Class   II)   classes,   

and    are    extended    to    include    aspects    related    to    end    user    devices.    Example    product    categories   
expected    to    adhere    to    this    class    include    (but    are    not    limited    to)    end    user    communication   
appliances,    such    as    IP    Phones,    PC-­‐based    softphones,    or    other    communication    appliances    that   
directly   support   the   end   user.   

Discovery   services   defined   in   this   class   include   provision   of   location   identifier   (including   ECS   /   E911   
information),   embedded   L2   switch   support,   and   inventory   management.

are   shown   below.   

1.    Voice    -­‐    for    use    by    dedicated    IP    Telephony    handsets    and    other    similar    appliances    supporting   

interactive    voice    services.    These    devices    are    typically    deployed    on    a    separate    VLAN    for    ease    of   
deployment   and   enhanced   security   by   isolation   from   data   applications.   

2.    Voice    Signalling    -­‐    for    use    in    network    topologies    that    require    a    different    policy    for    the    voice   
signalling   than   for   the   voice   media.
