LLDP table uses ID

Hey Guys,

I have a python script which constructs LLDP frame and sends it to the switch, example capture:

07:52:50.282224 LLDP, length 50
        Chassis ID TLV (1), length 18
          Subtype Local (7): 48:df:37:9c:fb:78
          0x0000:  0734 383a 6466 3a33 373a 3963 3a66 623a
          0x0010:  3738
        Port ID TLV (2), length 5
          Subtype Local (7): eth5
          0x0000:  0765 7468 35
        Time to Live TLV (3), length 2: TTL 120s
          0x0000:  0078
        Port Description TLV (4), length 4: eth5
          0x0000:  6574 6835
        System Name TLV (5), length 9: detcatod1
          0x0000:  6465 7463 6174 6f64 31
        End TLV (0), length 0

But when I attempt to fetch lldp neighbors I see this:

dudib@det_EX4600# run show lldp neighbors interface xe-0/0/2    
LLDP Neighbor Information:
Local Information:
Index: 927 Time to live: 121 Time mark: Sun May 10 08:01:14 2020 Age: 27 secs 
Local Interface    : xe-0/0/2
Parent Interface   : -
Local Port ID      : 516
Ageout Count      : 0

Neighbour Information:
Chassis type       : Locally assigned
Chassis ID         : 39373638-3935-5A43-4A39-333930353536
Port type          : Mac address
Port ID            : 48:df:37:9c:fb:78
Port description   : Embedded ALOM, Port 2

I have EX4600 switch, and in EX4550 this problem doesn't reproduce.
I want the Port Description to be eth5 and System Name to be shown, also I don't know why the chassis ID is that and not 48:df:37:9c:fb:78.

Thanks in advance
