 Layout of CDP Packets | CDP is the Cisco Discovery Protocol - which we receive and interpret, but don't send |
  CDP: Offsets of initial non-TLV items in a CDP packet. | The initial items are a checksum, protocol version, and the time to live of the packet |
| CDP: Sizes of the type and length portion of a CDP TLV entry. | Offsets of things that occur at the beginning of each TLV entry |
| CDP: Known values for TLV types | |
 CDP: Capability (CDP_TLV_CAPS) mask bits. | The TLV type CDP_TLV_CAPS value is a field with a set of bits defining the capabilities which a given switch or router might implement |
| 'FrameSet' data format on the wire | As noted earlier, FrameSets are logical packets |
| Generic TLV capabilities | Implements a set of client-oriented TLV (Type, Length, Value) capabilities |
| Layout of LLDP packets | The Link Layer Discovery Protocol is a layer two discovery protocol which we receive and interpret, but do not send |
| LLDP: offsets for LLDP packets | |
| LLDP: Known values for TLV types. | |
| LLDP: Methods of encoding Chassis ID. | |
| LLDP: Methods of encoding Port ID. | |
| LLDP: bit mask of switch capabilities. | |
| LLDP: IEEE 802.1 Organizationally specific TLV subtypes. | 802.1 Organizationally Specific TLVs – OUI == 00-80-C2 |
| LLDP: IEEE 802.3 Organizationally specific TLV subtypes. | 802.3 Organizationally Specific TLVs – OUI == 00-12-0F |
