Red Hat Linux Enterprise and CentOS
It is suggested to utilize "Yum" to get this installed if it is not.
"yum install tcpdump"
Run this command:
tcpdump -i any -w /tmp/capture.pcap
This will log on ANY interface and on ALL ports.
This can be limited down, for example if you wanted only port 8080 traffic:
tcpdump -i any port 8080 -w /tmp/capture.pcap
However, for most issues relating to Broadcom products - ANY/ALL is helpful and we can filter the results down using Wireshark.
