Step 3
vtp mode server Configures Switch A as the VTP server.
Step 4
end Returns to privileged EXEC mode.
Step 5
show vtp status Verifies the VTP configuration on both Switch A and Switch B.
Step 6
show vlan Verifies that the VLANs exist in the database on Switch A.
Step 7
configure terminal Enters global configuration mode.
Step 8
interface interface-id_1 Defines the interface to be configured as a trunk, and enters interface
configuration mode.
Step 9
switchport mode trunk Configures the port as a trunk port.
Step 10
end Returns to privileged EXEC mode.
Step 11
show interfaces interface-id_1 switchport Verifes the VLAN configuration.
Step 12
Repeat Steps 7 through 10 on Switch A for
a second port in the switch.
Step 13
Repeat Steps 7 through 10 on Switch B to
configure the trunk ports that connect to the
trunk ports configured on Switch A.
Step 14
show vlan When the trunk links come up, VTP passes the VTP and VLAN
information to Switch B. Verifies that Switch B has learned the VLAN
configuration.
Step 15
