BIG-IP systems may experience intermittent packet corruption while traffic passes through the High-Speed Bridge (HSB). The corruption may affect different parts of a packet, including MAC addresses, EtherType, IP or TCP headers, packet payloads, or checksums. Symptoms may include incomplete ARP entries, failed or unstable high availability or configuration synchronization, health monitor or pool instability, dropped connections, or TCP resets.
Packet corruption may cause network connectivity problems for some traffic passing through the affected HSB. Depending on the corrupted packet fields, the BIG-IP system may experience ARP resolution failures, dropped or rejected packets, invalid checksums, TCP resets, unstable health monitors, configuration synchronization problems, or high availability connection instability.
