Failure processing show lldp neighbors detail #129

Closed kaage closed 7 years ago

kaage commented 7 years ago

Description of Issue/Question

napalm-ios cannot process lldp neighbors detail on one of my swithces (probably because of some end devices speaking LLDP and having neighborship). I have plenty of similar switches with equal hardware and software and they are working.

Did you follow the steps from https://github.com/napalm-automation/napalm#faq

Setup

napalm-ios version

(Paste verbatim output from pip freeze | grep napalm-ios between quotes below)

napalm-ios==0.6.1

IOS version

(Paste verbatim output from show version between quotes below)

Error Traceback

(Paste the complete traceback of the exception between quotes below) This can be seen via Ansible:

[lldp_neighbors_detail] cannot retrieve device data: Failure processing show lldp neighbors detail
dbarrosop commented 7 years ago

Can you obscure the output somehow? We will need it to build a test case.

kaage commented 7 years ago

I did and also added it to issue description. I tried to be carefull and not change any structure of data. All names and serial numbers etc. are equal length with original ones (and identical type of characters).

ktbyers commented 7 years ago

@kaage Can you also get me the show lldp neighbors for this (obscure anything you need to obscure, but try to keep fields the same length).

I can work out making them consistent between the lldp details and the show lldp neighbors.

ktbyers commented 7 years ago

Okay, I think the one calling itself as 'not advertised' for system name is breaking it:

@kaage Never mind on the show lldp neighbors...I think I worked it out.

Here comes show lldp neighbors output: (unfortunately neighbors has changes meanwhile)

I can confirm this fix works as well.
