        }

It is not retrieving the line protocol information for the physical interfaces anymore like it did in version 2.4.2.0. We are running this playbook against both IOS and IOS XE devices.

EXPECTED RESULTS

It should return lineprotocol as before.

ACTUAL RESULTS

It is not returning lineprotocol information.

Hey @zaskan As reported in the bug here there have been updates in the IOS collection but no changes were made concerning the facts for which the bug is reported. And the change in ansible core has not much to change with how IOS as a collection itself behaves. Can you share some more config information for us to understand where the problem is? Even looking at the existing integration test cases I can see it is collecting lineprotocol information for the facts module to be specific. Thanks

Hi @KB-perByte. As you can see from the output below (ansible 2.4.2.0) the ios_facts module does return the lineprotocol information for a physical interface.

hey, @jepema can you specify the cisco.ios the collection version you are using? Thanks

[jepema]

Hi @KB-perByte, we are using version 2.2.0.

[KB-perByte]

Hey @jepema can you try with the latest release of the collection, and confirm if you find the problem is still there? As I mentioned I can see lineprotocol is being collected in the included tests of the collection. Thanks

[jepema]

Hi @KB-perByte, i will do that and report the results as soon as possible.

Thanks you.

[jepema]

Hi @KB-perByte, i have updated the cisco.ios collection as suggested.

/home/xxxxx/.ansible/collections/ansible_collections Collection Version cisco.ios 2.6.0

When i run the playbook again i still see no state for the lineprotocol.

[KB-perByte]

Hey @jepema & @zaskan sorry for getting back so late with the issue, as I mentioned I am able to verify that the module is collecting the lineprotocol information in our CI, I suspect that should be some data that is making the facts incomplete for you.

The base interface facts are the collective output of the following commands

        show interfaces
        show ip interface
        show ipv6 interface
        show lldp
        show cdp

Can you confirm some information on basis of the above commands shared.

1. is lineprotocol information missing for all the interfaces available or any specific interface.
2. if it is for the specific one as shared above can you share the show commands output for us to debug better, as the information is visible in my environment.
3. or is it different among aby specific IOS versions as you mentioned, as I am testing it with a IOS version 15.6(2)T and 16.3.01 where the facts look fine.

Regards

Hi @KB-perByte,

1. Is lineprotocol information missing for all the interfaces available or any specific interface? The lineprotocol information is only missing from physical interfaces. It is available for loopback and SVI interfaces.

2. If it is for the specific one as shared above can you share the show commands output for us to debug better, as the information is visible in my environment.

> 3. Or is it different among any specific IOS versions as you mentioned, as I am testing it with a IOS version 15.6(2)T and 16.3.01 where the facts look fine.
I ran the tests again against the following hardware:
IOS: Version 15.5(1)SY4, hardware is C6800 Series
IOS XE: Version 16.09.05, hardware is WS-C3850-48P
The result remains the same, lineprotocol information is missing.
