ftp data transfering drops when failover from active to backup

[gaojianwen]

Hi All,

I did a failover testing with 2 CSS11503 and found a ftp problem.

I ftp one file from the server which behind 2 CSS, I tried to force failover happen by shutdown external interface. The ftp transfering was also terminated.

How can I keep file still transfering when the active css failover to the backup one? Thanks.

I did not try it, but I believe it should work.

What version do you run ?

Hi Gilles,

The version is 8.10. It would be great if you can test it.

could you try to force failover by rebooting the CSS.

Just want to see if we get the same result.

I'm going on vacation tonight so I won't be able to test until july 15th.

You can open a service request with the TAC and they can test if for you.

Or you can wait till july 15th and I'll do it for you [just repost a question on that day so I do not forget]

Gilles,

The failover was successful while rebooting the active CSS. The transfering didn't drop.

Thanks.
