Purpose
Enter global configuration mode on Switch 1.
Configure a VTP administrative domain.
The domain name can be from 1 to 32 characters.
Configure Switch 1 as the VTP server.
Return to privileged EXEC mode.
Verify the VTP configuration on both Switch A and Switch B.
In the display, check the VTP Operating Mode and the VTP Domain
Name fields.
Verify that the VLANs exist in the database on Switch A.
Enter global configuration mode.
Enter interface configuration mode, and define Fast Ethernet port 0/1
as the interface to be configured as a trunk.
Configure the port as a trunk port.
Return to privilege EXEC mode.
Verify the VLAN configuration.
Repeat Steps 7 through 11 on Switch A for Fast Ethernet port 0/2.
Repeat Steps 7 through 11 on Switch B to configure the trunk ports on
Fast Ethernet ports 0/1 and 0/2.
When the trunk links come up, VTP passes the VTP and VLAN
information to Switch B. Verify that Switch B has learned the VLAN
configuration.
Enter global configuration mode on Switch A.
Enter interface configuration mode, and define the interface to set the
STP port priority.
Assign the port priority of 16 for VLANs 8 through 10.
Assign the port priority of 16 for VLAN 10.
Return to global configuration mode.
Enter interface configuration mode, and define the interface to set the
STP port priority.
Assign the port priority of 16 for VLANs 3 through 6.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
