I need to be able to see tcp traffic between client and F5 and between F5 and pool memebers. Anybody knows how I can setup and view that? Thanks

You can capture client side traffic and responding server side traffic using below command::

 

tcpdump -vvnni 0.0:nnnp -s0 host x.x.x.x and port yy
  • where x.x.x.x is Virtual IP and yy is virtual server port number

If you want to traffic for a specific client then::

 

tcpdump -vvnni 0.0:nnnp -s0 host x.x.x.x
  • where x.x.x.x is client IP

If you want write captured traffic to a file to review later in wire shark or some other tool use 'w' option and provide path to the file

 

tcpdump -vvnni 0.0:nnnp -s0 -w /var/tmp/capture.pcap host x.x.x.x
