Can't create VLAN's with Cisco Network Assistant

[Holzwurmch]

Hello everyone

I have a problem with my newest Switch, a WS-C2960X-48TS-L

Normaly I can programm all my Switches with Cisco Network Assistant. But now I have a problem with creating VLAN's. I can create them, safe them but after a refresh, all the new VLAN's are gone!

I updated the CNA to the newest Build 6.0 and updated the Switch to 15.2(2)E, but nothing helps!

Over the CLI I can do everything, but this is not a option for me! To programm sometimes a switch CNA is perfect for me! If it works!!

Thanks

So if you do it via CLI, you have no issue at all? Or have you tried this to verify?

Do you have STP enabled on the switch?

yes I can programm the vlan's over CLI. That's works. I have not tested this if its really works, but the VLAN's are programmed.

hmm I checked the STP / VTP settings with a second identical Switch, but there are no differents. Made a backup of one Switch and restore on the other One, but I'm still not able to create VLAN's.

however, I contacted my vendor today, he tell me that it shouldt be a problem to take back the switch. 

Best regards
