Updating MX Ports using Python API

[Edgar-VO]

Hi there,

I have been browsing through the forum and saw one thread for this item, but not using the same code examples. i would like to change the MX VLAN ports using the Python meraki API. This is different than the solution posted here where they use the request/REST function and not the api. I get a 200 Ok but the changing have not been done. I am a bit clueless now how to parse all this..

I want to update port 3 with a VLAN setting

A piece of code :

pay_load = "{'enabled': True, 'type': 'access', 'dropUntaggedTraffic': False, 'vlan': 400, 'accessPolicy': 'open'}"

pay_load = json.dumps(pay_load)

result = dashboard.mx_vlan_ports.updateNetworkAppliancePort(def_network,"3",param=pay_load)

meraki: INFO > MX VLAN ports, updateNetworkAppliancePort - 200 OK

But unfortunately no change in port

I think the problem is in parsing the arguments, but i am not sure ...

Any ideas ?

Hi,

Just to be sure. MX is bind to templated network or not ?

[Edgar-VO]

No,

The MX will be installed not using a template. I want to script a new and fresh installation

I'm not sure if is the problem but in the Documentation there is some underscore in the put request :

mx_vlan_ports_controller.update_network_appliance_port(collect)

ref: https://developer.cisco.com/meraki/api/#/python/api-endpoints/mx-vlan-ports/update-network-appliance-port

Your one is :

dashboard.mx_vlan_ports.updateNetworkAppliancePort

Dashboard is the session ID

dashboard = meraki.DashboardAPI(api_key)

in the documentation they only work with the REST API and python request . I can do that as well of course :

url = base_url+"/networks/"+my_network_id+"/appliancePorts/3"

payload = json.dumps({"enabled": "true","type":"access","vlan":"400"})

headers = {

'X-Cisco-Meraki-API-Key': api_key,

'Content-Type': 'application/json'

}

response = requests.request("PUT", url, headers=headers, data = payload)

print(response.text.encode('utf8'))

Then it works, but is not done using the official released meraki Python modules which you load with : import meraki

The function is actually expecting the parameters in a different way.

Try changing it to:

result = dashboard.mx_vlan_ports.updateNetworkAppliancePort(def_network,"3",vlan=400, accessPolicy="open", enabled = True, type="access",dropUntaggedTraffic=False)

[Edgar-VO]

Okay,

We are almost there 😉 that part works, however i want to have that part in a variable which i can easily manipulate

vlan=400, accessPolicy="open", enabled = True, type="access",dropUntaggedTraffic=False

cause this does not work

pay_load = 'enabled = True, type = "access", dropUntaggedTraffic = False, vlan = 400, accessPolicy = "open"'

result = dashboard.mx_vlan_ports.updateNetworkAppliancePort(def_network,"3",pay_load)

TypeError: updateNetworkAppliancePort() takes 3 positional arguments but 4 were given

Like this:

params = {
    "vlan":400,
    "accessPolicy":"open", 
    "enabled" : True,
    "type":"access",
    "dropUntaggedTraffic":False
}

dashboard.mx_vlan_ports.updateNetworkAppliancePort(def_network, 3, **params)

[Edgar-VO]

That works, thanks... been looking for that some time (but were afraid to ask 😉 )

basically using a dict variable and add/change values to it... Then the **params is setting a pointer to params values

Thnx for the help....

Yup kind of. In python terms it's called unpacking. If you want more information about it have a look here:
