textfsm 使用 junos 设置策略解析多行

问题描述

有一个几乎 10K 策略的 junos 配置，下面是一个例子：

每个政策可能包含或不包含 logoptions / Scheduler。 另一部分总是包含

示例 1

set logical-systems LS security policies from-zone Untrust to-zone Trust policy X match source-address 1.1.1.1/32
set logical-systems LS security policies from-zone Untrust to-zone Trust policy X match source-address 2.2.2.2/32
set logical-systems LS security policies from-zone Untrust to-zone Trust policy X match destination-address 3.3.3.3/32
set logical-systems LS security policies from-zone Untrust to-zone Trust policy X match destination-address 4.4.4.4/32
set logical-systems LS security policies from-zone Untrust to-zone Trust policy X match application Tcp-19094
set logical-systems LS security policies from-zone Untrust to-zone Trust policy X match application Tcp-9101
set logical-systems LS security policies from-zone Untrust to-zone Trust policy X then permit
set logical-systems LS security policies from-zone Untrust to-zone Trust policy 791 then log session-init
set logical-systems LS security policies from-zone Untrust to-zone Trust policy 791 then log session-close
set logical-systems LS security policies from-zone Untrust to-zone Trust policy X scheduler-name 2021-12-31

样本 2

set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match source-address 1.1.1.1/32
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match source-address 2.2.2.2/32
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match destination-address 3.3.3.3/32
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match destination-address 4.4.4.4/32
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match application Tcp-19094
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match application Tcp-9101
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X then permit
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X scheduler-name 2021-12-31

示例 3

set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match source-address 1.1.1.1/32
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match source-address 2.2.2.2/32
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match destination-address 3.3.3.3/32
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match destination-address 4.4.4.4/32
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match application Tcp-19094
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X match application Tcp-9101
set logical-systems LS1 security policies from-zone Untrust to-zone Trust policy X then permit

我写了一个这样的 textfsm 模板：

Value required Logicalsystem (\S+)
Value required Srczone (\S+)
Value required Destzone (\S+)
Value required Policyname (\S+)
Value List Srcaddr (\S+)
Value List Dstaddr (\S+)
Value List Application (\S+)
Value required Action (permit|deny)
Value List logoptions (\S+)
Value Scheduler (\S+)

Start
  ^set logical-systems ${Logicalsystem} security policies from-zone ${Srczone} to-zone ${Destzone} policy ${Policyname} match source-address ${Srcaddr}
  ^set logical-systems ${Logicalsystem} security policies from-zone ${Srczone} to-zone ${Destzone} policy ${Policyname} match destination-address ${Dstaddr}
  ^set logical-systems ${Logicalsystem} security policies from-zone ${Srczone} to-zone ${Destzone} policy ${Policyname} match application ${Application}
  ^set logical-systems ${Logicalsystem} security policies from-zone ${Srczone} to-zone ${Destzone} policy ${Policyname} then ${Action} -> Record
  ^set logical-systems ${Logicalsystem} security policies from-zone ${Srczone} to-zone ${Destzone} policy ${Policyname} then log ${logoptions} -> Record
  ^set logical-systems ${Logicalsystem} security policies from-zone ${Srczone} to-zone ${Destzone} policy ${Policyname} scheduler-name ${Scheduler} -> Record Start

理想输出：

['LS','Untrust','Trust','X',['1.1.1.1/32','2.2.2.2/32'],['3.3.3.3/32','4.4.4.4/32'],['Tcp-19094','Tcp-9101'],'permit',['session-init','session-close'],'2021-12-31']

实际输出：

['EBS','CHG202106221013_5',['10.168.96.26/32','10.168.96.27/32'],['10.187.224.11/32','10.187.224.12/32'],[],'']

我的 textfsm 模板的哪一部分是错误的？请纠正我。谢谢。
