Fixed In:
12.0.0, 11.5.1 HF5

Opened: Jun 06, 2014
Severity: 3-Major

Symptoms

VxLAN traffic cannot be evenly load balanced between tmms if limited outer IP addresses are used.

Impact

Reduce VxLAN traffic throughput.

Conditions

VxLAN configured.

Workaround

Modify sys db iptunnel.vxlan.udpport to value 0. It will cause BIGIP to treat vxlan traffic as regular UDP traffic and use UDP ports for disaggregation.

Fix Information

VxLAN packets are now treated as UDP packets by default in HW, which uses the port in addition to the IP address.
