This was fixed in 66d5f45

So is this error specific to me? Cause i still get it and i have the latest updates.

Seems to happen when Gi1/1 shows in the VLAN field, instead of just spaces and numbers

My template file matches the changes made at commit above:

Value TYPE (\S+)
Value VLAN (\S+)

[jmcgill298]

I'm not sure how you installed the templates, but if you did a git clone, then you can just pull down the latest updates. If you installed the templates in another way, then you would have to replicate the update into your environment.

[jmcgill298]

It doesn't appear that Netmiko is using the template that you have with the updates. I took your data and used it against the current template, and it parsed fine for me.

[alepodj]

Spot on! Thanks @jmcgill298 i manually downloaded the templates folder and copied/replaced the one in the python package as well as the parse.py and init.py for good measure and lo and behold it now works :)

Interesting part i only installed this package via package via pip and never touched it, so that's a head scratcher...but nonetheless is working now. Thanks a lot for the assist!

Cheers

[jmcgill298]

well pip installed the official release on PyPI. The update was pretty recent, and so PyPI has not had a new release added yet.
