vlan (global configuration) Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands vlan (global configuration) Use the vlan global configuration command to add a VLAN and to enter the config-vlan mode. Use the no form of this command to delete the VLAN. Configuration information for normal-range VLANs (VLAN IDs 1 to 1005) is always saved in the VLAN database. When VLAN Trunking Protocol (VTP) mode is transparent, you can create extended-range VLANs (VLAN IDs greater than 1005), and the VTP mode, domain name, and the VLAN configuration are saved in the switch running configuration file. You can save configurations in the switch startup configuration file by entering the copy running-config startup-config privileged EXEC command. vlan vlan-id no vlan vlan-id Syntax Description vlan-id ID of the VLAN to be added and configured. For vlan-id, the range is 1 to 4094. You can enter a single VLAN ID, a series of VLAN IDs separated by commas, or a range of VLAN IDs separated by hyphens. Defaults This command has no default settings. Command Modes Global configuration Command History Release 12.2(25)SEF Modification This command was introduced. Usage Guidelines You must use the vlan vlan-id global configuration command to add extended-range VLANs (VLAN IDs 1006 to 4094). Before configuring VLANs in the extended range, you must use the vtp transparent global configuration or VLAN configuration command to put the switch in VTP transparent mode. Extended-range VLANs are not learned by VTP and are not added to the VLAN database, but when VTP mode is transparent, VTP mode and domain name and all VLAN configurations are saved in the running configuration, and you can save them in the switch startup configuration file. When you save the VLAN and VTP configurations in the startup configuration file and reboot the switch, the configuration is selected in these ways: • 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 VTP mode is server, or if the startup VTP mode or domain names do not match the VLAN database, the VTP mode and the VLAN configuration for the first 1005 VLANs use the VLAN database information. If you try to create an extended-range VLAN when the switch is not in VTP transparent mode, the VLAN is rejected, and you receive an error message. 2-532 Cisco Catalyst Blade Switch for HP Command Reference OL-8916-01
