Configuring VTP Client Mode
When a switch is in VTP client mode, you cannot change its VLAN configuration. 
The client switch receives VTP updates from a VTP server in the VTP domain and 
then modifies its configuration accordingly.
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:
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 you do not assign the same 
password to each switch in the domain.
Step 5
exit Update the VLAN database, propagate it throughout the 
administrative domain, and return to privileged EXEC 
mode.
Step 6
show vtp status Verify the VTP configuration. In the display, check the 
VTP Operating Mode field.
