FTP and backup serverfarm issue

Hi All,

I am hitting a strange issue. For one of our clients, I have a VIP configured that serves FTP, HTTP and HTTPS. The config is as below. When I configure a backup serverfarm "http-maintenance.client.com-sf" under the loadbalance policy-map "CLIENT-VIP2-ANY-PM, passive FTP stops working. Active FTP continues to function properly so does HTTP and HTTPS. I am using ACE10 [version A2(3.5)].

Could anybody please advise ?

Regards,

Nilesh

FTP and backup serverfarm issue

Nilesh-

  Are you stating that you add the configuration in, and instantly all active ftp sessions grind to a halt? Or are you saying when you test your backup serverfarm configuration, the active sessions fail at that point?

Re: FTP and backup serverfarm issue

Hi Christopher,

Thank you for replying. Yes, when I add the configuration in, instantly all current/new ftp sessions stop functioning.

Nilesh-

  Sounds like a logic programming issue. Can you please get a TAC case opened to address this and report the bug ID back to the alias?

Regards,
