Affected Product(s):
F5OS F5OS-A
Known Affected Versions:
F5OS-A 1.8.4, F5OS-A 1.8.4-HR1
Opened: Sep 12, 2025 Severity: 2-Critical
On F5OS-A, a platform tcpdump capture on a specified physical interface captures ingress traffic but omits egress traffic for the same flow.
Interface-specific platform packet captures are incomplete and cannot reliably confirm whether egress traffic reaches the F5OS dataplane, delaying network troubleshooting.
- r5000, r10000, or r12000-series appliance - Platform-level tcpdump run against a specific physical interface, e.g. "system diagnostics tcpdump -i 3.0"
Capture on all interfaces (-i 0.0 / -i any) with a sufficiently narrow BPF filter. This captures both traffic directions but does not preserve interface-specific capture filtering.
