我创建了一个简单的 python 脚本来使用 RPC 命令从 rouer 获取 vpls mac 表。但是,它在运行时会引发错误。有人知道我做错了什么吗?
root@ubuntu:~# cat vpls3.py
#!/usr/bin/python3
from jnpr.junos import Device
from lxml import etree
import jxmlease
username='lab'
password='lab'
dev = Device(host='10.85.164.172', user=username, password=password, normalize=True)
dev.open()
#invoke the RPC command
sw = dev.rpc.get-vpls-mac-table()
print(etree.tostring(sw, encoding='unicode'))
根@ubuntu:~#
以下是错误:
root@ubuntu:~# python vpls3.py
Traceback (most recent call last):
File "vpls3.py", line 13, in <module>
sw = dev.rpc.get-vpls-mac-table()
NameError: name 'vpls' is not defined
root@ubuntu:~#
我也试过下面的脚本:
root@ubuntu:~# cat test1.py
from jnpr.junos import Device
from lxml import etree
# Set device information with IP-address, login user and passwort
dev = Device( user='lab', host='10.85.164.172', password='lab')
# Connect to the device
dev.open()
# Get MACs
macs = dev.rpc.get-vpls-mac-table(normalize=True)
# Print response of device
print (etree.tostring(macs))
# Close the connection
dev.close()
同样的错误:
root@ubuntu:~# python test1.py Traceback(最近一次调用最后):文件“test1.py”,第 11 行,在 macs = dev.rpc.get-vpls-mac-table(normalize=True) NameError: name 'vpls' 未定义 root@ubuntu:~#
