tcpdump filters

L2 Linker

Does anyone know what filters are supported for the tcpdump command on PAN-OS (7.0) ?
For troubelshooting of a Syslog (server) issue, due to large amounts of traffic, I need to capture only packets with syn- or fin/rst-flag set.
Something like this : # tcpdump 'tcp[tcpflags] & (tcp-syn|tcp-fin) != 0

 

Documentation found 'How To Packet Capture (tcpdump) On Management Interface' are sparse, as the filter options very well might be.

Thanks a lot Gereardo.

Seems like I got confused about the use of ' versus "

In my initial example the closing ' was also missing, This was a copy/paste glitch. Honest

Hi @aloke1.p,

 

TCPDUMP is specifically for the mgmt interface.

For dataplane interfaces you can use PCAP:
