Hi, I am just checking LLDP in mininet with OVS using wireshark. My question some data are encoding differently. I wish to know why it is? For example, chaissisId type is 1. But it is shown as 02 in your image. https://wiki.wireshark.org/LinkLayerDiscoveryProtocol?action=AttachFile&do=view&target=LLDP.png Same thing I observed in my testing also. do you have any specific encodign technique for LLDP data. Thanks for your explanation. Best regards Sothy
Hi, Be aware that the TLV type field is a subfield of this 16 bit field. it's only the seven most significant bits that constitute the subfield in question. Therefore the value of the subfield is '1', while the representation of the 16 bit field it comes from shows '0x0207' Thanks, Jaap ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: https://www.wireshark.org/lists/wireshark-users Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
