we have updated some IOS and then, CW LMS from 3.0.1 to 3.2.
After first upgrade, we can see for some devices, that LMS can sabe VLAN RUNNING. After upgradind LMS, the error persists.
We have compared model (3750) and IOS version (12.2(52SE)) and for some nodes it works, and it fails on others.
What else should we have a look at?
The way the vlan.dat is fetched is to telnet/SSH to the switch, then do a "copy flash:vlan.dat tftp:". Therefore, you need to make sure that RME can login to the switches via telnet or SSH, and that TFTP is allowed from the switch to the RME server.
