Opened: May 23, 2018
Severity: 4-Minor


On some BIG-IP platforms, tcpdump is unable to write verbose packet data to a file (e.g., 'tcpdump -nni 2.1:nn -e -vvv -s 0 -w /tmp/dump.pcap').


Cannot use tcpdump to write verbose packet data to file.


Use tcpdump with -w and -v options on a front panel interface that is actively sending/receiving traffic. This occurs on the following hardware: -- BIG-IP 5000,7000, 10000, i5000, i7000, i10000, i11000, and i15000 platforms. -- VIPRION B4400, B4300, B2200, and B2100 blades.


There is no workaround at this time.

Fix Information

The tcpdump operation is now able to write verbose packet data to file.
