Modifying a node in python

I am guessing you want to change the state of a given node, say from up to down. Or modify ltm node state user-down (or user-up) tmsh command equivalent. If so,

iControl REST call (sat is the name of the node and 192.168.1.1 is the management IP of the BIG-IP):

curl -sku admin:admin https://192.168.1.1/mgmt/tm/ltm/node/sat \
  -X POST -H 'Content-type: application/json' \
  -d '{"state":"user-down"}'

Python code:

from f5.bigip import ManagementRoot
mgmt = ManagementRoot('192.168.1.1', 'admin', 'admin')
node = mgmt.tm.ltm.nodes.node.load(name='sat', partition='Common')
node.update(state="user-down")

To print the field values of the object (tmsh list ltm node sat), add this one.

for key, value in node.__dict__.iteritems():
    print(" {}: {}".format(key, value))

If this is not what you are after, please post the tmsh equivalent command.

On uri: In the Node class, there is a field (property) called _meta_data: it does not exist in the tmsh world. It contains a dict, and one of the field is 'uri'. I do not know why Python complained, but possibly, updating the field is prohibited. To see the contents of uri, add the following:

print('uri is {}'.format(node._meta_data['uri']))

Cheers.
