TitleHow to troubleshoot why no information or just the MAC address is seen in the show lldp port remote-info port#
Objective
The possible root causes to only seeing either no information or just a MAC address when using the show lldp port remote-info port# on a switch
Environment
SecureStack
LLDP
Procedure
In order for the switch to fill in the remote-info fields of the connection:
1. Both the switch and the connection support LLDP protocol -Some older switches, Network Interface Cards, phones or other possible items may not support LLDP or just need a driver update to participate

2. The SecureStack will need to enable the LLDP setting and an example of the command is
set lldp port tx-tlv Option port#

Here is an example of the options available :
(su)->set lldp port tx-tlv ?
Command: set lldp Set LLDP configuration 
 
Object: port tx-tlv      Set the optional TLVs to be sent 
Usage: set lldp port tx-tlv {all | [port-desc] [sys-name] [sys-desc] [sys-cap] [mgmt-addr] 
                            [vlan-id] [mac-phy] [poe] [link-aggr] [max-frame] 
                            [med-cap] [med-loc] [med-poe] } <port-string> 
  
        all                Set all TLVs
        link-aggr  Include link aggregation TLV  
        mac-phy    Include duplex and bit rate TLV 
        max-frame  Include maximum frame size TLV  
        med-cap    Include med capabilities TLV  
        med-loc    Include med location TLV  
        med-poe    Include med power TLV  
        mgmt-addr  Include management address TLV  
        port-desc  Include port description TLV  
        poe        Include poe TLV  
        sys-cap    Include system capabilities TLV  
        sys-desc   Include system description TLV  
        sys-name   Include system name TLV  
        vlan-id    Include vlan id TLV

3. Configure the SecureStack with the following command to activate what it shares as well as what information it would like to know:
set lldp port tx-tlv all ge.1.2

To see the information that was shared  from the remote connection
(su)->show lldp port remote-info ge.1.2
Local Port   : ge.1.2      Remote Port Id : ge.2.17

If you are still not seeing the information from the other side of the connection then there is a possibility that the connecting unit does not support LLDP. 
 
Another option to learn to connection would be utilizing the command
show neighbor
which  uses CDP and even CiscoDP protocols to fill in the connecting devices details,if supported

 
(su)->show nei

Additional notes
The use of a free network analyzer such as Wireshark may help
by using filters to limit the display
lldp
cdp
these  can be combined in the filter field as: 
lldp && cdp
