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.
19.4 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
