VTP Mode Client Command on CISCO Router/Switch


VTP Mode Client


VTP client mode doesn’t allow you to create any VLANs. all VLANs must be learned from a server switch. This prevents the switch from accidently propogating VLANs throughout the network. Another use is to prevent an older switch from wiping out a server’s VLAN database due to it having a higher revision number.


Switch(config)#vtp mode client


In the below example we will set SW1 to be a VTP client, then add a VLAN. Notice the switch rejected the command.

SW1(config)#vtp mode client
Setting device to VTP CLIENT mode.
SW1(config)#vlan 542
%VTP VLAN configuration not allowed when device is in CLIENT mode.
