Nimbostratusfor switch vs member
we know the F5 can swtich traffic from failing member to good member quickly (almost 5 ms),now the guest want to add the delay into the process of the swiching process,so would we can change the switch process timing for any way?
- If you mean the failover from active to standby LTM, networks failover takes several seconds longer than serial failover, but other than that, there is no way to affect the failover timing
Most customers want faster, more seamless failover. Why do you want to introduce a delay?
/deb 
yan_haijin_3492because the custmer want use ltm for load balance database, u know the dababase server unload timing is so long ,they want increasing time for the database swtiching. thk u for u replay.waiting for u helping.- For failing servers over more slowly, I think the only option that might work for you is the "Manual Resume" feature in 9.4: (Click here)

/deb - yan_haijin_3492I read the document,I see u want me to using the Manual Resume function for manual switch to the good server, but I want auto switch the good server for several minutes, the lag time is the impotant inneed.waiting for u helping.

I do not think there is a way to accomplish this. BIG-IP is designed to move things over quickly. It was not designed to do things slowly. If there is a manual process involved in failing the databases over, then the BIG-IP failover could be manual as well.- yan_haijin_3492manually maybe can swich to the good server,but somebody must monitor the f5 ltm,and swtich the monitor by himself, I want the f5 ltm swtich the server auto, just waiting for sereval minutes.
- James_ThomsonYou will need to write a custom monitor in PERL, shell or compiled C to accomplish this.
