Updating F5 VIP using requests

You must use PATCH instead of POST. See https://devcentral.f5.com/wiki/icontrolrest.icontrolrestuserguide_v1300_3.ashx for details:

Modifying a resource with PATCH

Using the PATCH method, you can modify properties of a resource without affecting any other properties.

To modify an object in the BIG-IP® system configuration, specify the resource in the URI. Do not specify a collection in the URI.

PATCH https://192.168.25.42/mgmt/tm/pool/~Common~tcb-pool2
{"member": [{:name":"192.168.25.32:80", "description":"Tertiary web server"}] }

Adapted to python requests, it would for example translate to:

payload = {'description':'modified via REST'}
bigip.patch(BIGIP_URL_BASE + '/ltm/virtual/~Common~vipname',data=json.dumps(payload))

It seems like I can only patch the description. The following works

payload['description'] = 'test'

bigip.patch(BIGIP_URL_BASE + '/ltm/virtual/test5-http-virtual_python', data=json.dumps(payload))

but they did not work

payload['service port'] = '100'

payload['service_port'] = '100'

There is no property like this. If you plan to change the port, you need to alter the destination property instead. Try issuing an http GET on the same virtual first, then you can see the exact names and values of all properties.

Thank you, makes sense.

tatmotiv if you posted that as an answer the questioned could be flagged as answered now :)

Thank you, I did not have the option to mark the answer as a correct answer.
