Chapter 11 Configuring VTP Configuring VTP • Do not enable VTP Version 2 on a switch unless all of the switches in the same VTP domain are Version-2-capable. When you enable Version 2 on a switch, all of the Version-2-capable switches in the domain enable Version 2. If there is a Version 1-only switch, it does not exchange VTP information with switches that have Version 2 enabled. • If there are TrBRF and TrCRF Token Ring networks in your environment, you must enable VTP Version 2 for Token Ring VLAN switching to function properly. To run Token Ring and Token Ring-Net, disable VTP Version 2. Configuration Requirements When you configure VTP, you must configure a trunk port so that the switch can send and receive VTP advertisements to and from other switches in the domain. For more information, see the "Configuring VLAN Trunks" section on page 10-14. If you are configuring extended-range VLANs on the switch, the switch must be in VTP transparent mode. Configuring a VTP Server When a switch is in VTP server mode, you can change the VLAN configuration and have it propagated throughout the network. Note If extended-range VLANs are configured on the switch, you cannot change VTP mode to server. You receive an error message, and the configuration is not allowed. Beginning in privileged EXEC mode, follow these steps to configure the switch as a VTP server: Step 1 Step 2 Step 3 Command configure terminal vtp mode server vtp domain domain-name Step 4 vtp password password Step 5 end Step 6 show vtp status Purpose Enter global configuration mode. Configure the switch for VTP server mode (the default). Configure the VTP administrative-domain name. The name can be 1 to 32 characters. All switches operating in VTP server or client mode under the same administrative responsibility must be configured with the same domain name. (Optional) Set the password for the VTP domain. The password can be 8 to 64 characters. If you configure a VTP password, the VTP domain does not function properly if you do not assign the same password to each switch in the domain. Return to privileged EXEC mode. Verify your entries in the VTP Operating Mode and the VTP Domain Name fields of the display. When you configure a domain name, it cannot be removed; you can only reassign a switch to a different domain. To return the switch to a no-password state, use the no vtp password global configuration command. OL-8915-01 Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide 11-9
