Is it possible to change vservers according to a specified time?

I plan to use viprion 2250 blade as a TCP optimizer. I was wondering if it was possible to create several vservers with different TCP profiles, and have them changed automatically according to time. ...

Hi Shakoor,

its not possible to switch a VS configuration nor change entire TCP profiles within iRules (at least not without using a [SIDEBAND] connections pointing to the local iControl REST API - which I strongly wouldn't recommend to do^^)

The far better solution would be to use a periodic triggered 

iCall
script or even an external Management System (attached via REST API) to reconfigure the settings as required. The benefit of those approaches are, that they wouldn't affect the TMOS data plane at all (e.g. perform schedule checks on each TCP connection or even HTTP request etc). iCall or REST API would instead perform an Out-of-Band configuration change, without having an noticable performance impact...

Cheers, Kai
