Trunk link configs being changed.

All switches are in VTP transparent. Trunks set to "on" with VLANs pruned manually. Everything works fine. Recently, Trunk set to "auto" on one end, VLANs allowed set to 1-1005, none pruned. Only change made is to set VTP Domain Name. There are no VTP servers enabled.

Re: Trunk link configs being changed.

DTP when in auto mode contains the VTP domain name which is transmitted within the DTP frame, thus if DTP is being used the trunks will not form.
