Reference Multicast MAC addresses Some tools are not able to decode fw monitor Layer 2 header information properly. fw monitor stores it’s own information in the header fields designed for MAC addresses (Refer to fw monitor file format). This can be misinterpreted in some cases as Multicast MAC addresses. fw monitor file format Although fw monitor capture files are using the snoop file format the content is slightly different. fw monitor does not write down MAC addresses (12 bytes; 6 per MAC address) in the Layer 2 Frame header. Instead fw monitor writes down information about the interface and chain position where the packet was captured. If you do not use the –u or –s option or an older version of fw monitor the fields for the MAC addresses are used as follows: Byte 0 1 2 3 4 5 6 7 8 9 10 11 snoop file Source MAC address Destination MAC address fw Packet chain monitor direction positon file (i/I/o/o) Interface Name If you are using –u or –s the fields are used as follows: Byte 0 1 2 3 4 5 6 7 8 9 10 11 snoop file Source MAC address Destination MAC address fw Packet chain monitor direction positon file (i/I/o/o) Interface Name UUID / SUUID How to use fw monitor Page 69 of 70 Revision: 1.01
