Layer 4 to Layer 7 Services
Cisco Application Centric Infrastructure (ACI) treats services as a key part of an application. Any services that are required are treated as a service graph that is instantiated on the Cisco ACI fabric from the Cisco Application Policy Infrastructure Controller (APIC). You define the service for the application, while service graphs identify the set of network or service functions that the application requires.
Beginning with Cisco ACI Virtual Edge Release 1.2(1), Layer 4 to Layer 7 service graphs are supported for Cisco ACI Virtual Edge.
Beginning with the Cisco ACI Virtual Edge Release 2.2(1), support for Layer 4 to Layer 7 service graphs is extended to Cisco ACI Virtual Edge when it is part of Cisco ACI Virtual Pod.
For information about configuring Layer 4 to Layer 7 services on Cisco ACI Virtual Edge, see the Cisco APIC Layer 4 to Layer 7 Services Deployment Guide. However, you first must follow the guidelines and understand the limitations in the next section of this chapter.
When you follow instructions in the Cisco APIC Layer 4 to Layer 7 Services Deployment Guide, instead of configuring services on the VMware Distributed Virtual Switch (DVS) VMM domain, configure the services on the Cisco ACI Virtual Edge VMM domain with AVE as the switching mode.
