When "enable" parameter is "false" the VS does not appear in WebUI or bigip.conf

[cnicolorange]

Environment

• Application Services Version: 3.31.0
• BIG-IP Version: 15.1.4

Summary

I create an http virtual server with an AS3 declaration (parameter "enable" is true by default). I want to disable the VS, so I use an AS3 declaration like this: [{ "op": "add", "path": "/TR1/VIP-NTRZSMU001-TR1-443001/VIP-NTRZSMU001-TR1-443001/enable", "value": false }]

With this declaration the VS is disabled and when I use the GET method to retrieve the VS declarations I can see it with the parameter "enable" to "false". My problem is that when the parameter "enable" is false I don't see anymore the virtual server in WebUI or in the file bigip.conf. I use a tool that retrieves VS informations (address, pool members, state, etc.) with snmp get requests. As the VS doesn't appear in the configuration I can't see it in my tool.

Steps To Reproduce

Steps to reproduce the behavior:

1. Create a VS
2. Submit the following declaration:

[{ 
 "op": "add", 
 "path": "/TR1/VIP-NTRZSMU001-TR1-443001/VIP-NTRZSMU001-TR1-443001/enable",
 "value": false
}]

Expected Behavior

When I disable a VS with tmsh command "modify ltm virtual <VSname> disabled" I can see this VS in the WebUI and in the bigip.conf (with the state disabled) When I disable a VS with AS3 I want to have the same behavior.

Actual Behavior

When I disable a VS with AS3 I don't see it in the WebUI and in the bigip.conf (with the state disabled)

This is actually working as intended based on the original design of AS3. AS3 is "disabling" the VS by removing it from the configuration. I am changing this to a feature request to allow control over the virtual server enabled/disabled property.

@cnicolorange In order to help us better understand your use case, could you elaborate on why the current behavior of removing the ltm virtual configuration does not work for you?

Use case provided in duplicate issue #603:

The use case is to disable the VIP without removing the config from BIG-IP, so that a BIG-IP admin can quickly re-enable the VIP if needed via the GUI. Re-adding the VIP using AS3 can potentially cause significant delay and unnecessary down time.

Changing the state of an AS3 configured item via the GUI is not advised as this creates a divergence between the declared state and the existing state. If the declaration is re-applied, those manual changes will be undone.

Hello,

I answered a few days ago but I don't see it in the issue. I use a tool that retrieves VS informations (address, pool members, state, etc.) with snmp get requests. As the VS doesn't appear in the configuration I can't see it in my tool.

@cnicolorange Thank you for the additional information on your use case. I believe this monitoring use case is one of the stronger arguments for this feature request.
