Cannot FTP via Filezilla to some of my OS6860 switches

[jimallenson]

So I am trying to upgrade the software in my OS6860 and OS6860E switches via Filezilla. I have found that with some of the switches, I cannot connect via Filevilla (Filezilla just errors out) and some connect just fine. I have tried finding the trigger causing this issue but the configs and software versions are identical.

Any help would be greatly appreciated.

you need to activate ssh at the switch (aaa authentication ....) and use sftp to the switch from Filezilla (with default port 22). It shoud work. If not.... newest version of filezilla. Can you use ssh to your switch? Sometimes the time of the switch is the reason - use ntp. And sometimes the source interface associated with the service.....
