About DAG modes for BIG-IP scalability

BIG-IP scalability relies on load balancing (parallelizing) the processing of incoming packets across a large number of TMMs (cores). This is accomplished with various disaggregation algorithms. This section provides a concise description of these algorithms. Note, selecting the wrong disaggregation mode can have a severe impact on performance.

DAG is configured per VLAN. Note, this means that the client and server sides of BIG-IP should be configured on different VLANs. So it’s possible to configure different DAG modes for client and server connections. However, when a server responds to a client request, and a connection is already established, DAG is not used.
