Standard SNMP community stops completing cluster config

[Otimun]

Environment

• Declarative Onboarding Version: 1.25.0
• BIG-IP Version: 15.1.4

Summary

After succesfully creating the cluster configuration, the cluster tries to synchronize and delete the snmp community that is not found in the declarative onboarding procedure (standard public community). When this deletion fails, the configuration is rolled back.

When using cloud init to remove the snmp community beforehand everything works.

It seems that the standard SNMP community that is configured cannot be deleted by DO. perhaps this is because the command structure is diferent? To remove this object, rather than deleting it you need to modify/patch it. the cli command is:

tmsh modify sys snmp communities delete { comm-public }

rather than:

tmsh delete sys snmp communities comm-public

Steps To Reproduce

Steps to reproduce the behavior:

1. Submit the following declaration: any declaration with a cluster build.

2. Observe the following error response:

Expected Behavior

DO to be able to delete the non used standard SNMP community without rolling back the configuration.

Actual Behavior

You need to manually delete the snmp community before running DO to make the cluster configuration work.

Thank you for your feedback. I have added this to our internal product backlog as AUTOTOOL-2879.

Any update on this backlog item?

We're also experiencing this as well. Currently working around this in the same way, runing the tmsh command to remove the group before the apply.
