SUMMARY

If a VRF is configured on an interface it causes parsing to fail.

STEPS TO REPRODUCE

1. Attempt to execute aruba_aoscx_show_interface.textfsm against a device which contains at least one interface assigned to a VRF.

EXPECTED RESULTS

Interfaces are parsed successfully.

ACTUAL RESULTS

A parsing error occurs:

Parsing failed for 'show interface' command:

Traceback (most recent call last):

SUMMARY

If a VRF is configured on an interface it causes parsing to fail.

Hi @Christophoclese
Similar to a couple of other issue tickets (including #2252).

Are you interested in working up fixes for this AOS-CX sh interface changes?

(See #2243 for my guidance. Thank you!)

@Christophoclese
Are you interested in working up a pull request (PR) for Aruba AOS-CX show interface?

[Christophoclese]

Hey @mjbear,

I wasn't really clear on what would be a reasonable course of action here. Do we want to make a new variable for VRF? Do we just want to consume that line? How do you handle text that may appear?

[mjbear]

Do we want to make a new variable for VRF? Do we just want to consume that line?

If the VRF name is useful to you then it's probably not a bad idea to capture it.

Edit: My thought is it's probably handy to capture. If I were you I'd add the VRF.

How do you handle text that may appear?

If you can provide test data showing things that sometimes appear, then those should be accounted for within the template. (We want to include test data in your PR that covers any of the lines that are added to the template.)

@Christophoclese
(Like the note on a different issue ticket ... we can take these one-at-a-time.)
Are you willing to work up a PR for this Aruba sh interface output with VRFs?
