A10 Thunder ADC Integration with Cisco ACI

Cisco ACI APIC enables interoperability between a Cisco ACI environment and management, orchestration,

virtualization and L4-L7 services. With A10 Harmony, developers can integrate intelligent application

networking services more easily with high-performance A10 Thunder Series product lines.

Cisco APIC requires a plugin, referred to as a device package, to communicate with the Thunder ADC physical

or virtual devices. The A10 device package contains the XML conﬁguration ﬁle with A10 device speciﬁcations

and Python scripts that allow the APIC to interface with A10 devices and deploy services. Figure 7 shows the

A10 device package integrated with Cisco ACI architecture.

This integration between A10 and Cisco ACI ensures that network segmentation and security policies are

enforced consistently whenever a new application is deployed in the network. Cisco APIC can now manage

an A10 device and conﬁgure L4-L7 ADC services using RESTful API (aXAPI) commands as the device package

provides the translation from APIC callouts to A10 aXAPI commands. The integration leverages A10’s ACOS

which is completely API driven, enabling delivery of rich services programmatically.
