Hello All,

I got a requirement where the fallback persistence is needed to apply. Since I never worked on it, not sure how to assign it to the virtual server. Can someone please provide the steps to create a fallback persistence or how to apply it? I checked using “list ltm persistence” command but don’t see it there.

f5 version - 11.5.4

Thank you,

R

If you have no experience then it might be easier for you to just assign a fall-back persistence from the GUI.

FWIW in tmsh the fallback is fallback-persistence

You’d set the persistence with something like

```tcl
modify vs_name fallback-persistence fb-persist-profile

```

and create (Before you add it obviously) the persistence profile via something like

```tcl
create /ltm persistence source-addr profile-name

```

The type (Where I have source-addr) can be one of the supported types. e.g. cookie, src/dst-addr etc.
