IOS SLB and Stateless failover

Trying to compare CSM and IOS SLB features. Read where the CSM can have "stateful" failover (maintains sessions) in a box-to-box scenerio. I also read where the IOS SLB can only provide "stateless" failover (I assume during failover, state/connection information is lost) using HSRP.

Can anyone confirm what I have written?

Your help is much appreciated.

Re: IOS SLB and Stateless failover

That is correct.

The CSM can maintain state on connections on a failover using the "replicate csrp" command. This command is not available on IOS SLB.

The following are links to the CSM commands and IOS SLB commands for your reference...
