Lab B.6: Configuring VTP
In this lab, you will configure the 1900A switches with a VTP domain name,
configure the second switch as a client, and verify that VTP information is
updated from the server to the client.
1.
Telnet or connect a console to the 1900A switch. Set the switch to be
a server VTP switch. (This is the default, but type it in anyway for
practice.)
1900A#config t
1900A(config)#vtp server
2.
Set the VTP domain name to Classroom1.
1900A#config t
1900A(config)#vtp domain Classroom1
3.
Verify that the VTP information is configured correctly.
1900A#show vtp
4.
Telnet or connect to 1900B, set the VTP domain name, and set the
VTP mode to client.
1900B#config t
1900B(config)#vtp domain Classroom1
1900B(config)#vtp client
5.
Verify both switches' VTP configuration by using the show vtp com-
mand. Also verify that the VLAN information is propagated from the
server switch to the client by using the show vlan command.
6.
From 1900B, type show vlan to see if the VLAN information was
propagated from the 1900A switch.
