Add basic support for Stratix switches

[Christophoclese]

Environment

• ntc-templates version: 8.1.0

Proposed Functionality

Expand existing Cisco IOS regexes to include patterns for Allen-Bradley.

Use Case

Allen-Bradley manufactures switch devices under the Stratix product line. These devices run Cisco IOS & Cisco IOS XE Software. show version for IOS currently fails to parse the value for HARDWARE due to the line beginning with Allen-Bradley and not Cisco.

I was able to work around this by modifying Line 35 of ./ntc_templates/templates/cisco_ios_show_version.textfsm to ^([Cc]isco|Allen-Bradley)\s+${HARDWARE}\s+\(.+\).+

Or would it be possible to just parse the Model Number instead like line 48?:

ntc-templates/ntc_templates/templates/cisco_ios_show_version.textfsm

Line 48 in 3f1a8bc

^[Mm]odel\s+[Nn]umber\s+:\s+${HARDWARE}\s*

Interesting find with those industrial switches - they do run IOS-XE and there's a Cisco partnership. 😅

Or would it be possible to just parse the Model Number instead like line 48?:

ntc-templates/ntc_templates/templates/cisco_ios_show_version.textfsm

Oooof, there's no Error directive in the Start state or the Stack state.
Though this might be one of the templates where it's not quite feasible to have the Error directive.

I wonder if there's enough variety of test data for show version if someone were to add in the Error directive (if possible).

Line 48 in 3f1a8bc
^[Mm]odel\s+[Nn]umber\s+:\s+${HARDWARE}\s*

If we add the Model line for coverage (similar to L48), it would match later and overwrite what was captured earlier (L35). (Edit: The value overwriting in this case could actually be a good thing. 🙂)

❓ Would you please include the raw output from the CLI in a code fence? (not as a Python data structure)

[Christophoclese]

This was my first foray into TextFSM & ntc-templates, thanks for the quick feedback. From my limited testing, only show version is affected, however I've only worked with: show version, show interfaces, show vlan, show etherchannel summary, show ip interface, show interfaces switchport, & show cdp neighbors detail as part of Nautobot's Device Onboarding.

Here is the raw output from another S5200:

Welcome 🙂

Cool - templates get updated as needed or as reported. 😅
It's good you reported this for the sake of the Allen-Bradleys and Stratix. 😁

@Christophoclese Would you want to draft up a pull request with test data?
(Or is that something I should work on when time permits?)

@Christophoclese
Up for producing a pull request (PR) for these changes?

Here are some tips:

1. Fork the ntc-templates repo
2. Clone to your local PC
3. Initialize Poetry on your local PC
4. Create a feature branch
5. Make template changes
6. Add raw test data
7. Generate parsed test data via helper scripts
8. Run tests via invoke
9. Commit those changes to your local repo
10. Push changes from your local repo to your GitHub forked repo of ntc-templates
11. Compare and create a pull request (PR) at ntc-templates
