Opened: Jul 24, 2021 Severity: 3-Major
When using DPDK driver and multiqueue, only TCP traffic will get hashed and distributed between different TMMs.
UDP traffic will get funneled to only a single TMM causing excess CPU usage on that TMM.
- DPDK driver is being used. - Multiqueue is enabled and is in use. For a list of NICs that use DPDK, see K17204: BIG-IP VE NIC adapters that support SR-IOV, available at: https://support.f5.com/csp/article/K17204
Disable multiqueue.
