 Hi, I am trying to do something which I thought would be fairly simple using the EOS API, alas it is causing me some issues. I want to run the command “show interfaces” via the JSON API and then extract and print various bits of information. I have started off simple by (trying) to extract the MTU. This is my Python code: import json
import jsonrpclib
from jsonrpclib import Server
switches = ["10.2.7.170"]
username = "admin"
password = "admin"
# Going through all the switch IP addresses listed above
for switch in switches:
urlString = "https://{0}:{1}@{2}/command-api".format(username, password, switch)
switchReq = Server( urlString )
# Display the current interface list
response = switchReq.runCmds( 1, ["show interfaces"] )
dataString = json.loads(jsonrpclib.history.response)
dataDump = json.dumps(dataString,sort_keys=True,indent=2)
parent = dataString["result"][0]["interfaces"]
for item in parent:
print item["mtu"]
However when I execute I get the following error: Traceback (most recent call last):
File “getInte.py”, line 25, in <module>
print item[“mtu”]
TypeError: string indices must be integers Any suggestions on how I can correctly extract the MTU information? Here is the raw JSON output from EOS |

If you want to quickly see all of the values for the interfaces on the switch, you can import pprint and pprint the value, try this:
from jsonrpclib import Server from pprint import pprint #---------------------------------------------------------------- # Configuration section #---------------------------------------------------------------- SWITCH_IP = 'SWITCH IP or NAME' USERNAME = 'USERNAME PASSWORD = 'PASSWORD' #---------------------------------------------------------------- def main(): switch = Server( 'https://%s:%s@%s/command-api' % ( USERNAME, PASSWORD, SWITCH_IP ) ) response = switch.runCmds( 1, [ 'show interfaces' ] ) interfaces = response[ 0 ][ 'interfaces' ] for intf, value in interfaces.iteritems(): print "--- Interface %s ---" % intf pprint(value) print if __name__ == '__main__': main()
