DAG round robin

You can use the
DAG Round Robin
setting on a VLAN to prevent stateless traffic from overloading a few TMM instances, a condition that can disable an entire BIG-IP system. When enabled, this setting causes the BIG-IP system to load balance the traffic among TMMs evenly, instead of using a static hash. Stateless traffic in this case includes non-IP Layer 2 traffic, ICMP, some UDP protocols, and so on. This setting is disabled by default.
This feature is particularly useful for firewall and Domain Name System (DNS) traffic. For example, this feature prevents certain types of DDoS attacks, such as an ICMP DDoS attack that can overload the system by sending the same packets repeatedly to a specific subset of TMMs.
The disaggregation of traffic occurs only to TMMs that are local to a given high-speed bridge (HSB).
