  ULDP does not  compact with similar protocols of other vendors, which means users 
can not use ULDP on one end and use other similar protocols on the other end. 
  ULDP function is disabled by default. After globally enabling ULDP function, the debug 
switch can be enabled simultaneously  to check the debug information. There are 
several DEBUG commands provided to print debug information, such as information of 
events, state machine, errors and messages. Different types of message information 
can also be printed according to different parameters. 
  The  Recovery timer  is  disabled  by default  and  will  only  be  enabled  when the  users 
have configured recovery time (30-86400 seconds). 
  Reset  command  and  reset  mechanism  can  only  reset  the  ports  automatically  shut 
down by ULDP. The ports shut down manually by users or by other modules won’t be 
reset by ULDP.
