我试图运行一个脚本来显示所有的配置,并将它们写入juniper和CISCO路由器的文件中。到目前为止,CISCO脚本可以正常工作,但是问题是与juniper路由器有关。
for ii in JUNIPER:
print ii
cmd2 = 'show configuration | display set'
conn.connect(ii)
conn.login(account1)
conn.execute(cmd2)
print conn.response
#filerouter = open(ii, "w")
#filerouter.write(conn.response)
#filerouter.close()在获得了要查询的设备列表之后,我运行了这个程序,但是它被卡住了,就好像有一个缓冲区的限制.-
如果我尝试执行另一个命令:
("show configuration | display set | match destination ")
--我把输出写在文件或屏幕上。
C:\Python27>python.exe C:\User\suserrr\Downloads\shrun.py

默认情况下,JunOS对任何命令返回的冗长输出进行分页。可能发生的情况是,连接到的Juniper设备正在对show configuration | display set命令的输出分页,而Exscript正在超时,因为该设备正在等待用户输入以继续对命令的输出分页,而不是返回Exscript识别的提示符。
我要作以下修改:
for ii in JUNIPER:
print ii
cmd2 = 'show configuration | display set | no-more'
conn.connect(ii)
conn.login(account1)
conn.execute(cmd2)
print conn.response这将禁用该特定命令的输出分页,并应立即返回到提示符,并允许Exscript将输出返回给您。为了更好地衡量,我还添加了一辆马车返回我的命令,即:
cmd2 = 'show configuration | display set | no-more\r'但是,做上面的工作是否有用还有待商榷,似乎我正确地记得execute()方法应该会为您做这件事。

对于使用python处理Junos设备,我建议您使用PyEZ - https://github.com/Juniper/py-junos-eznc。
from jnpr.junos import Device
from lxml import etree
dev = Device('hostname', user='username', password='Password123')
dev.open()
cnf = dev.rpc.get_config() # similar to 'show configuration | no-more' on cli
print (etree.tounicode(cnf))
dev.close()发布于 2018-02-01 22:43:49
我使用这个脚本使用PyEZ和JSON来使用多个IP地址。
from jnpr.junos import Device
from lxml import etree
import json
config_file = open('config.json')
config = json.load(config_file)
config_file.close()
for host in config['ip']:
dev = Device(host=host, user=config['username'],
password=config['password'], port=22)
dev.open()
data = dev.rpc.get_config(options={'format':'set'})
file_name = dev.facts['fqdn']
print(etree.tostring(data))
dev.close()
f = open(file_name + '.txt', 'w')
f.write(etree.tostring(data))
f.close()JSON文件如下所示:
{
"username": "user",
"password": "password",
"ip": [
"10.255.6.100",
"10.255.6.101",
"10.255.6.102",
"10.255.6.103",
"10.255.6.104"
]
