Chapter 8 Configuring VLANs
Using VTP
Caution Do not configure a VTP domain name if all switches are operating in VTP client mode. If you do so, it
is impossible to make changes to the VLAN configuration of that domain. Therefore, make sure you
configure at least one switch as the VTP server.
Beginning in privileged EXEC mode, follow these steps to configure the switch for VTP client mode:
Disabling VTP (VTP Transparent Mode)
When you configure the switch for VTP transparent mode, you disable VTP on the switch. The switch
then does not send VTP updates and does not act on VTP updates received from other switches.
However, a VTP transparent switch does forward received VTP advertisements on all of its trunk links.
Beginning in privileged EXEC mode, follow these steps to configure the switch for VTP transparent
mode:
Command Purpose
Step 1
vlan database Enter VLAN database mode.
Step 2
vtp client Configure the switch for VTP client mode. The default setting is VTP server.
Step 3
vtp domain domain-name Configure a VTP administrative-domain name. The name can be from 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.
Step 4
vtp password password-value (Optional) Set a password for the VTP domain. The password can be from 8 to
64 characters.
If you configure a VTP password, the VTP domain does not function properly if
youdonotassignthesamepasswordtoeachswitchinthedomain.
Step 5
exit Update the VLAN database, propagate it throughout the administrative domain,
andreturntoprivilegedEXECmode.
Step 6
show vtp status Verify the VTP configuration. In the display, check the VTP Operating Mode
field.
Command Purpose
Step 1
vlan database Enter VLAN database mode.
Step 2
vtp transparent Configure the switch for VTP transparent mode.
The default setting is VTP server.
This step disables VTP on the switch.
Step 3
exit Return to privileged EXEC mode.
Step 4
