F5 – TCPDump Basics

Problem

Needing to monitoring the traffic on an F5.

Solution

Running a packet capture over SSH and then grabbing the file using sftp or winscp.

tcpdump -s0 -nni 0.0 host <Client_IP> and port <number> and host <VS_IP> -w /var/tmp/Monitor_Resets.pcap

 where:
-s0 gives the complete packet.
-nni disable service port lookups, dns lookups and specifies internal interface

 

All the rest of the options can be found at F5 here.
