Explanation: 
1.  Both Ethernet2 of switch A and Ethernet1 of switch B are the ports of network connection 
device,  they  will  not  send  LLDP  packets  with  MED  TLV  information  forwardly.  Although 
configure Ethernet1 of switch B to send MED TLV information, it will not send the related 
MED  information,  that  results  the  corresponding  Remote  table  without  the  related  MDE 
information on Ethernet2 of switch A. 
2.  LLDP-MED  device  is  able  to  send  LLDP  packets  with  MED  TLV  forwardly,  so  the 
corresponding Remote table with LLDP MED information on Ethernet1 of switch A. 
15.4 LLDP-MED Troubleshooting 
If problems occur when configuring LLDP-MED, please check whether the problem is caused 
by the following reasons: 
  Check whether the global LLDP is enabled. 
  Only network connection device received LLDP packets with LLDP-MED TLV from the 
near MED device, it sends LLDP-MED TLV. If network connection device configured 
the command for sending LLDP-MED TLV, the packets also without LLDP-MED TLV 
sent  by the  port, that means  no MED  information is  received and  the port does  not 
enable the function for sending LLDP-MED information. 
  If neighbor device has sent LLDP-MED information to network connection device, but 
there  is  no LLDP-MED  information  by  checking  show  lldp  neighbors  command,  that 
means LLDP-MED information sent by neighbor is error.
