Disabling Vtp (Vtp Transparent Mode) - Cisco Catalyst 2950 Software Configuration Manual

Configuring VTP
Use the no vtp mode global configuration command to return the switch to VTP server mode. To return
the switch to a no-password state, use the no vtp password privileged EXEC command. When you
configure a domain name, it cannot be removed; you can only reassign a switch to a different domain.
Note You can also configure a VTP client by using the vlan database privileged EXEC command to enter
VLAN configuration mode and entering the vtp client command, similar to the second procedure under
"Configuring a VTP Server" section on page
to return the switch to VTP server mode or the no vtp password VLAN configuration command to return
the switch to a no-password state. When you configure a domain name, it cannot be removed; you can
only reassign a switch to a different domain.

Disabling VTP (VTP Transparent Mode)

When you configure the switch for VTP transparent mode, you disable VTP 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 all of its
trunk links.
Before you create extended-range VLANs (VLAN IDs 1006 to 4094), you must set VTP mode to
Note
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:
Command
Step 1
configure terminal
Step 2 vtp mode transparent
Step 3 end
Step 4
show vtp status
Step 5
copy running-config startup-config
To return the switch to VTP server mode, use the no vtp mode global configuration command.
If extended-range VLANs are configured on the switch, you cannot change VTP mode to server. You
Note
receive an error message, and the configuration is not allowed.
