Template update: cisco_ios_show_vlan to get interface list

[lboue]

Hello,

I am trying to improve your template called cisco_ios_show_vlan.template to get interface list for each VLAN
You can see that this file cisco_ios_show_vlan.raw contains "Ports" column.

ISSUE TYPE

I have an issue with the Template Creation

TEMPLATE USING

Value VLAN_ID (\d+)
Value NAME (\S+)
Value STATUS (\S+)
Value List PORTS (\S.+)

Start
  ^VLAN\s+Type -> Done
  ^${VLAN_ID}\s+${NAME}\s+${STATUS}\s+$PORTS -> Record
  ^\s+$PORTS -> Record

SUMMARY

I new some help to fix my template proposal because I don't how to copy VLAN_ID variable for the second to N row for each VLAN.

STEPS TO REPRODUCE

Apply the previous template against cisco_ios_show_vlan.raw

EXPECTED RESULTS

 - vlan_id: '1'
   name: 'default'
   status: 'active'
   ports: 'Gi0/1'

Ludovic,

There is really only a hack way around this, I have asked to extend the capability from the developers, but have not heard back. Adding a +1 may help to highlight the issues: google/textfsm#18

Hello Ken ,

Thanks for asking RepeatedItem to the developers.
I managed to get close to the expected result. But I still have to split the PORTS value in an external script.

Value NAME (\S+)
Value STATUS (\S+)
Value List PORTS (\S.+)

Start
  ^VLAN\s+Type -> Done
  ^\S -> Continue.Record
  ^${VLAN_ID}\s+${NAME}\s+${STATUS}\s+${PORTS}
  ^${VLAN_ID}\s+${NAME}\s+${STATUS}
  ^\s+${PORTS}

Done

Here is the result a this template against your raw file cisco_ios_show_vlan.raw

python textfsm.py vlan.tmpl cisco_ios_show_vlan.raw
FSM Template:
Value VLAN_ID (\d+)
Value NAME (\S+)
Value STATUS (\S+)
Value List PORTS (\S.+)

Start
  ^VLAN\s+Type -> Done
  ^\S -> Continue.Record
  ^${VLAN_ID}\s+${NAME}\s+${STATUS}\s+${PORTS}
  ^${VLAN_ID}\s+${NAME}\s+${STATUS}
  ^\s+${PORTS}

Done


FSM Table:
['VLAN_ID', 'NAME', 'STATUS', 'PORTS']
['1', 'default', 'active', ['Gi0/1']]
['10', 'Management', 'active', []]
['50', 'VLan50', 'active', ['Fa0/1, Fa0/2, Fa0/3, Fa0/4, Fa0/5, Fa0/6, Fa0/7, Fa0/8, Fa0/9', 'Fa0/10, Fa0/11, Fa0/12']]
['60', 'VLan60', 'active', ['Fa0/13, Fa0/14, Fa0/15, Fa0/16, Fa0/17, Fa0/18, Fa0/19, Fa0/20', 'Fa0/21, Fa0/22, Fa0/23, Fa0/24']]
['1002', 'fddi-default', 'act/unsup', []]
['1003', 'token-ring-default', 'act/unsup', []]
['1004', 'fddinet-default', 'act/unsup', []]
['1005', 'trnet-default', 'act/unsup', []]

Can I send a merge request?

Can you take a look at what was done here:

@lboue I put together something last night. I think it is good, but it was getting late, so I need to review it again; then I will put in a PR for review
