Enable/ Disable LLDP feature. 
The interval among each LLDP message (5~32768s). 
TTL value is used to configure neighbor info’s age time on local devices. TTL = 
Min  (65535,  (TTL  multiplier  ×  LLDP  packet  sending  time  interval)).  Through 
adjusting  TTL  multiplier,  you  can  control  this  device  info's  age  time  on  the 
neighboring device (2~10s). 
When  local  configurations  change,  each  LLDP  packet  will  be  sent  after  one 
sending delay time (1~8192s and <= sending time interval/4). 
To  avoid  constant  port  initialization  caused  by  frequent  changes  of  working 
mode, you can configure port initialization delay time. When port's working mode 
changes, the initialization will be delayed for some time (1~10s).
