我正在尝试基于完整配置文件创建一个 cisco 基本配置。

以下是完整文件配置的一些示例：

    !
    policy-map QOS
     class GOLD
      priority percent 10
     class SILVER
      bandwidth 30
      random-detect
     class default
    !
    interface Loopback1
     description Management
     ip address 9.9.9.9 255.255.255.255
    !
    interface FastEthernet0/0
     description LAN
     ip address 6.6.6.6 255.255.255.0
    !
    ip access-list standard customer_internal
     permit 1.1.1.1
     permit 2.2.2.2
     permit 3.3.3.3
    !

我发现了这个 ciscoconfparse 库（https://pypi.python.org/pypi/ciscoconfparse）。并且能够将配置行块抓取到另一个文件中，但不知道如何将块排除到基本配置文件中。

from ciscoconfparse import CiscoConfParse

full_config_for_parse = file('./fullconfig.txt')
basic_config_file = open('./basic_config.txt', 'w') # This file needs to contain only basic config, like interface, IP, etc...
security_config_file = open('./security_config_file.txt', 'w') # This is the file that was able to send the line blocks

parse = CiscoConfParse(full_config_for_parse)

class_map = parse.find_all_children('class-map')
access_list = parse.find_all_children('ip access-list')

if class_map != ' ':   # If class_map is not empty, it means that the full config file has class-map configuration, so, it needs to be removed or not copied to basic config file
    for line in class_map:
        security_config_file.write(line)  # separating the blocks to another file
        #basic_config_file.write(remove_this_line) I need to delete/not write this line to basic_config_file

if access_list != ' ':
    for line in access_list:
        security_config_file.write(line)
        #basic_config_file.write(remove_this_line)


# There is another code part that is copying all the rest of the basic configuration to basic_config_file, that is working OK

files.close()

任何人都知道删除或不将这些配置块复制到基本配置文件的更好方法吗？

经过大量的研究和尝试，得到了我想要的，用现在可以工作的新代码编辑答案：

from ciscoconfparse import CiscoConfParse

def main():

    # 2nd Part - Begin 
    p = CiscoConfParse("./basic_config.txt")
    basic_config_NEW = open('./basic_config_NEW.txt', 'w') # Need to open a new file as using the same one was getting empty file

    for obj in p.find_objects(r'^class-map'):
        obj.delete('class')

    for obj in p.find_objects(r'^ip access-list'):
        obj.delete('ip access-list')

    for line in p.ioscfg:
        basic_config_NEW.write(line)  # This was adding the lines without break lines on the file
        basic_config_NEW.write('\n')  # Have to add it not sure if there is another way of doing it in one single line

    basic_config_NEW.close()        

    # 2nd Part - End

if __name__ == "__main__":
    main()

据我所知，您想从我的答案底部的配置中删除policy-map和，并将结果另存为.ip access-listbasic_config.txt

这是最有效的方法...

from ciscoconfparse import CiscoConfParse

parse = CiscoConfParse('fullconfig.txt')

objs = list()
objs.extend(parse.find_objects(r'^policy-map'))    # Append policy-map obj
objs.extend(parse.find_objects(r'ip\saccess-list'))# Append ip access-list obj

for obj in objs:
    # When you delete a parent obj, it recurses through all children
    obj.delete()
parse.commit()

parse.save_as('basic_config.txt')  # Save the new configuration

当您查看时basic_config.txt，它将具有以下几行...

!
!
interface Loopback1
 description Management
 ip address 9.9.9.9 255.255.255.255
!
interface FastEthernet0/0
 description LAN
 ip address 6.6.6.6 255.255.255.0
!
!

文件名：fullconfig.txt...
