vtp (global configuration) Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands Defaults The default filename is flash:vlan.dat. The default mode is server mode. No domain name or password is defined. No password is configured. Pruning is disabled. The default version is Version 1. Command Modes Global configuration Command History Release 12.2(25)SEF Modification This command was introduced. Usage Guidelines When you save VTP mode, domain name, and VLAN configurations in the switch startup configuration file and reboot the switch, the VTP and VLAN configurations are selected by these conditions: • If both the VLAN database and the configuration file show the VTP mode as transparent and the VTP domain names match, the VLAN database is ignored. The VTP and VLAN configurations in the startup configuration file are used. The VLAN database revision number remains unchanged in the VLAN database. • If the startup VTP mode is server mode, or the startup VTP mode or domain names do not match the VLAN database, VTP mode and VLAN configuration for the first 1005 VLANs are selected by VLAN database information, and VLANs greater than 1005 are configured from the switch configuration file. The vtp file filename cannot be used to load a new database; it renames only the file in which the existing database is stored. Follow these guidelines when configuring a VTP domain name: • The switch is in the no-management-domain state until you configure a domain name. While in the no-management-domain state, the switch does not send any VTP advertisements even if changes occur to the local VLAN configuration. The switch leaves the no-management-domain state after it receives the first VTP summary packet on any port that is trunking or after you configure a domain name by using the vtp domain command. If the switch receives its domain from a summary packet, it resets its configuration revision number to 0. After the switch leaves the no-management-domain state, it can no be configured to re-enter it until you clear the NVRAM and reload the software. • Domain names are case-sensitive. • After you configure a domain name, it cannot be removed. You can only reassign it to a different domain. 2-556 Cisco Catalyst Blade Switch for HP Command Reference OL-8916-01
