This REST API provides a programmatic model-based interface for configuring classic ASAs, beginning with the 9.3.2
release. The term “classic ASAs” refers to appliances which don’t include CX or SourceFire Sensor, or the integrated

functionality of NGFW (next-generation firewall) services. Also note that when other security modules are present with a

classic ASA, there are no APIs for those modules.

The REST API can be used to configure ASAs in conjunction with existing management interfaces and applications—
command-line interface (CLI), Adaptive Security Device Manager (ASDM) and Cisco Security Manager (CSM).

New features in REST API 1.2.2:

•  Smart Licensing.
•  Support for IP Audit and for additional application inspection protocols (FTP, NetBIOS, RTSP, SIP, SQL*Net).
•  Ability to query for the ASA’s serial number.

• REST API 1.2.2.200 release includes a fix for CSCux92088: Increase the limit of bulk api request entries

to 1000.

New features in REST API 1.2.1:

• Monitoring support for multi-context mode.
• Support for the following ASA features: DHCP Server and Relay, DNS Client and Dynamic DNS, Protocol

Timeouts (PTO), and GTP inspection.
