Thanks Luis. My question is now more on encoding of LLDP data. See the screen shot I taken in mininet side. Data for chassis (binary view) is showing as 02 07 04 00 00 00 00 00 01. In my question, why 2 in binary view.
Same for port id also, 04 02 07 32 . port id type is encoded as04. Port id 2 is encoded as 32. TTL TLV: 06 02 13 37. Why TTL type is encoded as 06. What is specification for encoding these LLDP data?
