Configuring VTP
Disabling VTP (VTP Transparent Mode)
When you configure the switch for VTP transparent mode, VTP is disabled on the switch. The switch
does not send VTP updates and does not act on VTP updates received from other switches. However, a
VTP transparent switch running VTP Version 2 does forward received VTP advertisements on its trunk
links.
Note Before you create extended-range VLANs (VLAN IDs 1006 to 4094) , you must set VTP mode to
transparent by using the vtp mode transparent global configuration command. Save this configuration
to the startup configuration so that the switch boots up in VTP transparent mode. Otherwise, you lose
the extended-range VLAN configuration if the switch resets and boots up in VTP server mode (the
default).
Beginning in privileged EXEC mode, follow these steps to configure VTP transparent mode and save the
VTP configuration in the switch startup configuration file:
To return the switch to VTP server mode, use the no vtp mode global configuration command.
Note If extended-range VLANs are configured on the switch, you cannot change the VTP mode to server. You
receive an error message, and the configuration is not allowed.
Note You can also configure VTP transparent mode by using the vlan database privileged EXEC command
to enter VLAN database configuration mode and by entering the vtp transparent command, similar to
the second procedure under the “Configuring a VTP Server” section on pag e 13-9. Use the no vtp
transparent VLAN database configuration command to return the switch to VTP server mode. 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.
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 vtp mode transparent Configure the switch for VTP transparent mode (disable VTP).
Step3 end Return to privileged EXEC mode.
Step4 show vtp status Verify your entries in the VTP Operating Mode and the VTP Domain
Name fields of the display.
Step5 copy running-config startup-config (Optional) Save the configuration in the startup configuration file.
Note Only VTP mode and domain name are saved in the switch running
configuration and can be copied to the startup configuration file.
