Introduction to Cisco DNA Center APIs
Cisco DNA Center is a centralized network management and automation platform used in software-defined networks (SDN).
It helps organizations design, deploy, manage, secure, and troubleshoot their networks.
APIs (Application Programming Interfaces) in Cisco DNA Center allow external applications, scripts, and security tools to interact with the network programmatically instead of manual configuration.
In simple terms:
Cisco DNA Center APIs allow software to control, monitor, and secure the network automatically.
These APIs are mostly RESTful APIs, meaning they use:
- HTTP methods (GET, POST, PUT, DELETE)
- JSON data format
- Secure authentication (token-based)
Why Cisco DNA Center APIs Are Important (Exam Focus)
Cisco DNA Center APIs are used to:
- Automate network deployment
- Apply consistent configurations
- Monitor network health and security
- Detect issues faster
- Integrate with security platforms (SIEM, SOAR, NAC, etc.)
For the 350-701 exam, you must understand:
- What tasks the APIs perform
- How they improve security and operations
- Which API functions relate to provisioning, optimization, monitoring, and troubleshooting
Categories of Cisco DNA Center APIs
Cisco DNA Center APIs are commonly grouped into four main functional areas:
- Network Provisioning APIs
- Network Optimization APIs
- Network Monitoring APIs
- Network Troubleshooting APIs
Each category supports automation and security visibility.
1. Cisco DNA Center APIs for Network Provisioning
What Is Network Provisioning?
Network provisioning means:
- Adding new network devices
- Configuring switches, routers, wireless controllers, and access points
- Applying policies and templates automatically
How APIs Help in Provisioning
Cisco DNA Center provisioning APIs allow:
- Automatic device onboarding
- Configuration deployment using templates
- Assignment of devices to sites and locations
- Consistent configuration across the network
Key Capabilities
Using APIs, an organization can:
- Discover new devices in the network
- Push configurations without manual CLI access
- Assign VLANs, IP addressing, and network roles
- Deploy wireless SSIDs and security settings
IT Environment Example
- A script uses Cisco DNA Center APIs to:
- Add 100 new access switches
- Apply security baseline configurations
- Enable secure management protocols
- Assign them to specific network sites
This reduces configuration errors and improves security consistency.
Security Benefits
- Eliminates misconfiguration risks
- Ensures secure templates are always applied
- Supports zero-touch provisioning (ZTP)
2. Cisco DNA Center APIs for Network Optimization
What Is Network Optimization?
Network optimization means:
- Improving performance
- Ensuring efficient use of bandwidth
- Enhancing user and application experience
How APIs Help in Optimization
Optimization APIs allow software to:
- Analyze traffic patterns
- Adjust network policies dynamically
- Optimize wireless coverage and performance
- Apply Quality of Service (QoS) settings
Key Capabilities
APIs can:
- Identify congestion points
- Adjust path selection
- Optimize wireless radio settings
- Apply application-aware policies
IT Environment Example
- An automation system:
- Reads application performance data via APIs
- Detects poor performance for business applications
- Adjusts QoS policies automatically to prioritize them
Security and Operational Benefits
- Prevents performance degradation attacks
- Ensures critical services remain available
- Reduces manual tuning errors
3. Cisco DNA Center APIs for Network Monitoring
What Is Network Monitoring?
Network monitoring involves:
- Tracking device health
- Monitoring traffic, users, and applications
- Detecting abnormal behavior
How APIs Help in Monitoring
Monitoring APIs allow external tools to:
- Collect real-time and historical network data
- Monitor device and interface status
- Track user and endpoint activity
- Observe application performance
Key Capabilities
Using APIs, administrators can:
- Retrieve network health scores
- Monitor CPU, memory, and link utilization
- Identify unauthorized devices
- Track endpoint location and behavior
IT Environment Example
- A SIEM system:
- Pulls telemetry data from Cisco DNA Center APIs
- Correlates it with security logs
- Detects suspicious network activity
Security Benefits
- Improves visibility into the network
- Enables faster detection of threats
- Supports compliance monitoring
4. Cisco DNA Center APIs for Network Troubleshooting
What Is Network Troubleshooting?
Troubleshooting involves:
- Identifying network problems
- Finding root causes
- Resolving issues quickly
How APIs Help in Troubleshooting
Troubleshooting APIs allow automation tools to:
- Run diagnostics
- Perform path trace analysis
- Identify misconfigurations
- Analyze failures
Key Capabilities
APIs can:
- Collect logs and error data
- Run network path analysis between endpoints
- Detect configuration mismatches
- Provide root cause analysis information
IT Environment Example
- A monitoring system:
- Detects a drop in network health
- Automatically queries Cisco DNA Center APIs
- Identifies the failing device and interface
- Generates a remediation alert
Security and Operational Benefits
- Faster incident response
- Reduced downtime
- Improved forensic investigation
Authentication and Security of Cisco DNA Center APIs
Authentication
Cisco DNA Center APIs use:
- Token-based authentication
- Secure HTTPS communication
- Role-based access control (RBAC)
Only authorized users and applications can access API functions.
Security Controls
- API access can be limited by role
- Sensitive data is protected
- Integration supports security platforms like:
- SIEM
- SOAR
- Identity services
Why Cisco DNA Center APIs Matter for Security (Exam Key Point)
Cisco DNA Center APIs support:
- Secure automation
- Centralized visibility
- Faster threat detection
- Policy enforcement
- Integration with security ecosystems
They are a critical part of modern enterprise network security architecture.
Exam Summary (Must Remember)
