The VTP update requirements are met by the default CatOS operation, but the Cisco IOS software update model requires an alternative update operation. VTP client and server systems require VTP updates from other VTP servers to be immediately saved in NVRAM without user intervention.
In contrast, Cisco IOS software does not save configuration changes to NVRAM unless you issue the copy run start command. VLAN or VTP configuration changes in CatOS are written to NVRAM immediately after a change is made. Refer to Cisco Technical Tips Conventions for more information on document conventions.
