[Budoor Nagaraju]

Hi

New to Junos pyez , my requirement is to move the interface to the vlans , have studied couple of document but unable to succeed here is the below script can someone help me ?

 import sys
from sys import argv
from jnpr.junos import Device
from jnpr.junos.utils.config import Config
from jnpr.junos.exception import *
from jnpr.junos.op.ethport import EthPortTable
from pprint import pprint
import getpass
import os

dict = {}
dict['ip1'] = "host1"

target_host = raw_input('device name: ')
target_interface = raw_input('Interface name: ')
vlan=raw_input('vlan id: ')
dev = Device(host=target_host, user='user1', password='password', interface=target_interface)
dev.open()
change=Config(dev)
#vlan=argv[1]
cmd=("delete interface $target_interface")
cmd=("set interfaces 'target_interface' unit 0 family ethernet-switching vlan members 'vlan'")
change.load(cmd, format ='set')
print 'diff from junos device:'
print change.pdiff()
change.commit()
dev.close()
exit()

Change below line

 

cmd=("set interfaces 'target_interface' unit 0 family ethernet-switching vlan members 'vlan'")

 

 

to

 

cmd="set interfaces {0} unit 0 family ethernet-switching vlan members {1}".format(target_interface, vlan)

 

 

Thanks

Nitin Kr

There are now spaces between interfaces, ge-0/0/46,and unit in the configuration you generated.

cmd="set interfaces{0}unit 0 family ethernet-switching vlan members{1}".format(target_interface,vlan)

This explains why the generated configuration had no spaces. There are no spaces in your format string. Change the above line to:

cmd="set interfaces {0} unit 0 family ethernet-switching vlan members {1}".format(target_interface,vlan)
