I want to parse a Checkpoint Firewall cphaprob -a if executed via Netmiko using TextFSM. The final generated list is not well formatted.
I already tried a lot of TextFSM combination of commands but maybe I just fail to understand how it properly works.
Below is the cphaprob -a if original output. I want to parse the virtual context (e.g 'vcont 0'), interface names (e.g 'bond0'), virtual interfaces (e.g 'bond0.2121') and their hostnames (e.g '10.105.0.42').
vcont 0:
------
Required interfaces: 2
Required secured interfaces: 1
eth0 UP non sync(non secured), multicast
eth1 UP sync(secured), broadcast
Virtual cluster interfaces: 1
eth0 10.105.0.42
vcont 1:
------
Required interfaces: 3
Required secured interfaces: 1
eth1 UP sync(secured), broadcast
bond0 UP non sync(non secured), multicast, bond Load Sharing (bond0.2101)
bond1 UP non sync(non secured), multicast, bond Load Sharing (bond1.2126)
Virtual cluster interfaces: 3
bond0.2121 10.65.29.21
bond1.2122 10.65.29.22
bond1.2123 10.65.29.23
vcont 2:
------
Required interfaces: 3
Required secured interfaces: 1
eth1 UP sync(secured), broadcast
bond1 UP non sync(non secured), multicast, bond Load Sharing (bond1.2127)
bond0 UP non sync(non secured), multicast, bond Load Sharing (bond0.2102)
Virtual cluster interfaces: 2
bond1.4242 10.65.29.42
bond0.4243 10.65.29.43

As you can see I only get the 1st occurrence of the virtual interfaces and their corresponding IP addresses. The reason may be that in my template in Cluster state I record right after ^${VirtualInterface}\s+${IPv4} -> Record Start. I just can't figure out how to get all virtual interfaces and IP addresses in their corresponding lists.

Value List Interface (\S+)
Value List VirtualInterface (\S+)
# Add escaping for "."
Value List IPv4 (\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})

^${Context}:
^${Interface}.*(UP|DOWN|Disconnected)
^Virtual cluster interfaces: \d+ -> Cluster
Cluster
^${VirtualInterface}\s+${IPv4}
# The reason for the multiple VirtualInterface and IPv4 entries
# is because you Record after each match.
# Instead, you can Record after you have matched all entries.
# I look for what I know will be the start of the next entry in table,
# and use Continue.Record.
# Continue will continue looking for matches for the current line that is being parsed,
# but will move onto the next regex line, instead of starting back at the top of State.
# Another thing about Continue, is that you cannot do that and have a State Change,
# which is why I change to the Start state afterwards
^.+: -> Continue.Record
^${Context}: -> Start
