WebWhen filtering for most protocol identifiers on FDDI, Token Ring, or 802.11, tcpdump checks only the protocol ID field of an LLC header in so-called SNAP format with an Organizational UnitIdentifier (OUI) of 0x000000, for encapsulated Ethernet; it doesn't check whether the packet is in SNAP format with an OUI of 0x000000. The exceptions are: iso WebStatic Ethernet header generation with predefined parameters: EtherType = 0x88F7, or Message Type = Opcode 0 (sync), or PTP version = 0 ; Predefined pattern mode generation with interpacket gap of two cycles and payload size of 57 bytes for each packet. 128 packets generate every second.
