The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter contains the following sections:
Supported Response Formats
The REST API plug-in supports the JavaScript Object Notation (JSON) format for a response. For JSON response, specify Accept: application/json in the HTTP header as shown in the following example:
GET /api/n1k/summary HTTP/1.1 Host: 10.10.10.2 Accept: application/json Authorization: Basic YWRtaW46U2Zpc2gxMjM=
To specify the JSON response format through cURL, use the following:
curl -u <user>:<password> <vsm-ip>/api/n1k/port-profile -H "Accept: application/json"
The following example shows the response received in the JSON format:
{ "":{"url":"/api/n1k/summary", "properties":{"vcStatus":"Connected", "vcIpaddress":"10.197.132.200", "switchMode":"ADVANCED (3.0)", "ip":"10.197.132.213","vcUuid":"e7 4f 03 50 3f ab 39 42-67 c9 dc 40 9f 74 45 91", "name":"switch", "datacenterName":"Test-DC", "haStatus":true, "mode":"L2", "version":"version 5.2(1)SV3(1.3) [build 5.2(1)SV3(1.2.100)]", "connectionName":"vc" } } }
The REST API plug-in supports the XML format for a response. For XML response, specify Accept: application/xml in the HTTP header as shown in the following example:
GET /api/n1k/summary HTTP/1.1 Host: 10.10.10.2 Accept: application/xml Authorization: Basic YWRtaW46U2Zpc2gxMjM=
To specify the XML response format through cURL, use the following:
curl -u <user>:<password> <vsm-ip>/api/n1k/port-profile -H "Accept: application/xml"
The following example shows the response received in the XML format:
<?xml version="1.0" encoding="utf-8"?> <instance url="/api/n1k/summary"> <properties> <vcStatus>Connected</vcStatus> <vcIpaddress>10.10.10.4</vcIpaddress> <switchMode>Advanced</switchMode> <ip>10.10.10.2</ip> <vcUuid>12 57 2f 50 07 e8 b4 ea-1c 0e ba 78 23 52 96 3e</vcUuid> <name>n1kv-cy</name> <datacenterName>Sample-DC</datacenterName> <haStatus>true</haStatus> <mode>L3</mode> <version>version 4.2(1u)SV2(2.1au) [build 4.2(1)SV2(2.1a)]</version> <connectionName>vcenter</connectionName> </properties> </instance>
Supported HTTP Methods
The GET method lists the entities in a specific resource. The format of the GET method is as follows:
/api/n1k/<resource>
The following is an example of the GET method in cURL:
curl -u admin:password 10.10.10.2/api/n1k/port-profile/profile1 -H "Accept: application/json" { "profile1": { "url": "\/api\/n1k\/port-profile\/profile1", "properties": { "minPorts": 1, "description": "", "switchportMode": "trunk", "state": false, "name": "profile1", "portBinding": "static", "portGroupName": "", "capability": "", "maxPorts": 32, "type": "Vethernet" } } }
The POST method creates a new instance of a resource or updates the identified instance. To create a new resource, the format of the POST method is as follows:
/api/n1k/<resource>
The following is an example of the POST method to create an instance of a resource in cURL:
curl -X POST -u admin:password 10.10.10.2/api/n1k/port-profile -d '{ "name" : "profile1", "switchportMode" : "access", "shutdown" : false}' Successfully created "port-profile profile1"
To modify a specific instance, the format of the POST method is as follows:
/api/n1k/<endpoint>/<instance>
The following is an example of the POST method to modify a specific instance in cURL:
curl -X POST -u admin:password 10.10.10.2/api/n1k/port-profile/profile1 -d '{ "switchportMode" : "trunk", "shutdown" : false}’ Successfully modified "port-profile profile1"
The DELETE method deletes the specified instance. The format of the DELETE method is as follows:
/api/n1k/<resource>/<instance>
The following is an example of the DELETE method in cURL:
curl -u admin:password -X DELETE 10.10.10.2/api/n1k/port-profile/profile1 Successfully deleted "port-profile profile1"
