Fixed In:

Opened: Dec 08, 2017

Severity: 3-Major


Received frames may be delivered in groups of four leading to added latency.


This will impact production traffic as extra latency will be introduced to incoming traffic before the tmm can process it.


BIG-IP VE using a ixlv virtual function (Intel X710/XL710/XXV710 NIC with SR-IOV) on the very first attach after a reboot of the underlying compute host (hypervisor). Packets will appear to arrive in groups of 4 to virtual servers and selfips via tmm.


Restart tmm or reboot the guest at least once after starting it following a reboot of the physical compute host on which it runs.
