Changing Virtual Server's Access Profile with TMSH w/o Knowing Its Current Value

Probably best to list ltm virtual one-line first so you know all the other profile you have attached as well if you replace-all-with.

Ok so how would I preserve all those other profiles and just replace the Access Profile specifically?

Well, you would have to put them all into the curlies with the new profile. Its actually probably much easier to "list ltm virtual VS_name profiles" to gather the list of profiles and just use your original add/delete tmsh since you are querying what the original profile was anyway.

This isn't that easy because some of the profiles have dependencies on iRules and other configuration objects. I would suggest that you explicit remove the old one with a known name.

I'm still not understanding how you propose to discover which profile is the Access Profile exactly. If I list out the profiles it gives me all profiles, not just Access Profiles. So if I were to get a list of all profiles, then replace them all with the new Access Profile, then add back all the original profiles, would I not still be adding back the original Access Profile in addition to the new one?

@Walter Kacynski So if the question instead were, "How do I get the value a Virtual Server's Access Profile property is set to?" would this just not be doable?

Try using a well structured naming convention. In my environment I name all of my Access profiles with "Access". Since you can only have one applied then when doing a list you know what is what.

good reason for naming convention that help with this like _access or _ap when you create profiles and other objects.

Unfortunately, I don't have control over the Access Profile naming conventions my tmsh scripts my encounter. If there's no easier way, I may just list out all the Access Profiles and compare them against profiles listed for the VS and delete any that match before doing my add.
