Read data from one specific interface

Is there a way to retrieve information from one spesific interface, rather than looping through all the interfaces and choosing the correct one?

I find the latter approach to be very inefficient in terms of the time it takes to loop through all available interfaces, and am looking for a better and faster way.

 

Here is my current code:

 

from ydk.models.cisco_ios_xe.Cisco_IOS_XE_interfaces_oper import Interfaces
from ydk.services.netconf_service import NetconfService
from ydk.providers.netconf_provider import NetconfServiceProvider service = NetconfService() provider = NetconfServiceProvider(address=address, username=username, password=password)
model = Interfaces()
interfaces = service.get(provider=provider, read_filter=model)
for interface in interfaces.interface:
if interface.name == "GigabitEthernet0/0/7":
return "some data"

Try this script (change interface name and device credentials):

import logging
import ydk.models.cisco_ios_xe.Cisco_IOS_XE_interfaces_oper as ifc_oper
from ydk.services.netconf_service import NetconfService
from ydk.providers.netconf_provider import NetconfServiceProvider

def enable_logging(level):
log = logging.getLogger('ydk')
log.setLevel(level)
handler = logging.StreamHandler()
formatter = logging.Formatter(
"%(asctime)s - %(name)s - %(levelname)s - %(message)s")
handler.setFormatter(formatter)
log.addHandler(handler)

if __name__ == "__main__":
enable_logging(logging.INFO)
service = NetconfService()
provider = NetconfServiceProvider(address="ios-xe-mgmt-latest.cisco.com",
port=10000,
username="developer",
password="C1sco12345")

model = ifc_oper.Interfaces()
ifc = ifc_oper.Interfaces.Interface()
ifc.name = "GigabitEthernet3"
model.interface.append(ifc)

interface = service.get(provider=provider, read_filter=ifc)

 I got this from XE sandbox:

Hi,

 

Seems like there is no alternative method get a specific Interface entity through YDK's Cisco_IOS_XE_interfaces_oper

 

http://ydk.cisco.com/py/docs/gen_doc_d3c0b5efefaadaf38699df0c6c6e43bd0355e31c.html

 

Maybe you could loop through all the interface once, and store it as a python dictionary. So that you can get the Interface entity directly in next time.

 

Here is an example, please verify / fix the code if there is any syntax error.

 

interfaces = service.get(provider=provider, read_filter=model)
interfaces_dict = {}

for interface in interfaces.interface:
tmp = {interface.name : interface}
interfaces_dict.update(tmp)

print(interfaces_dict['GigabitEthernet0/0/7'].if_index)
