  • Useful Wireshark Display Filters

    While it is always possible to use capture filters (which have their own syntax), experience has shown that it is usually better to capture everything on the wire and then use display filters to zero in on the desired packets.

    One specific device                 ip.addr == xxx.xxx.xxx.xxx

    Two specific devices               ip.addr == xxx.xxx.xxx.xxx  and  ip.addr == xxx.xxx.xxx.xxx

    Either of two devices              ip.addr == xxx.xxx.xxx.xxx  or  ip.addr == xxx.xxx.xxx.xxx

    Sending IP device                   ip.src == xxx.xxx.xxx.xxx

    Receiving IP device                ip.dst == xxx.xxx.xxx.xxx

    BACnet traffic with Application layer message                           bacapp

    Who-Is,  I-Am, UnconfirmedCOVNotification , etc.             bacapp.unconfirmed_service

    Who-Is                                                                                       bacapp.unconfirmed_service==8

    I-Am                                                                                          bacapp.unconfirmed_service==0

    UnconfirmedCOVNotification                                                 bacapp.unconfirmed_service==2

    BACnet messages with Network layer                                         bacnet

    Network layer messages (w/o Application Layer)                     bacnet.control_net ==1

    Who-Is-Router-To-Network                                                      bacnet.mesgtyp==0

    I-Am-Router-To-Network                                                         bacnet.mesgtyp==1

    Either of the above with a specific network "y"                        bacnet.mesgtyp==x and bacnet.dnet==y

    BACnet/IP traffic                                                                         bvlc

    Write-Broadcast-Distribution-Table                                          bvlc.function==1

    Forwarded-NPDU                                                                     bvlc.function==4

    Distribute-Broadcast-To-Network                                             bvlc.function==9
