An engineer seeks a solution to retrieve routing information from Cisco Nexus switches. The data must be exported to a web application in a JSON or XML data format for monitoring and must be encrypted during transmission. The solution must not require extensive knowledge to support and should be simple to implement.
Which technology accomplishes these goals?
NX-API is a RESTful API available in Cisco Nexus switches that allows the retrieval of various types of data, including routing information. It supports JSON and XML formats for data representation, making it suitable for exporting to a web application. Additionally, NX-API can use HTTPS for secure communication, ensuring that the data is encrypted during transmission. The solution is designed to be simple to implement and does not require extensive knowledge to support, aligning well with the engineer's requirements.
Agree, NX-API is a RESTful API that allows retrieving various information, including routing data, from the switches, responses are typically formatted in JSON or XML.
SNMP uses the polling method, which requests information each time information is acquired, but Telemetry uses the subscription method. Regarding transport, SNMP is a UDP-only implementation, but Telemetry uses gRPC in addition to UDP/TCP and uses a flow-controlled transport layer. SNMP uses ASN. However, The NX-API CLI is a web interface through which commands traditionally entered via the CLI, can be encoded using either XML or JSON, and transmitted via HTTP or a secure transport (HTTPS) to the device. The commands are executed on-box and responses are returned in either XML or JSON format
