I have a Catalyst Switch 3524XL with IOS 12.0(5)WC9a. Currently, I manage this switch through interface VLAN 10 instead of the default interface VLAN 1. This switch is configured as a VTP transparent mode and is connected to a Catalyst 4507 in VTP server mode. I try to connect this 3524XL switch to a new 6509 switch in VTP server mode and try to change management IP address and VLAN interface, but it was unsuccessful. I changed ip default-gateway to point to the new 6509 switch. What else am I missing? I don't think VTP status is the problem here. Please correct me if I am wrong. Any advises would be appreciated. Thank you.
