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.
