Purpose
Configure the port as a trunk port.
Return to global configuration mode.
Repeat Steps 2 through 4 on Switch 1 interface Fast Ethernet 0/2.
Return to privileged EXEC mode.
Verify your entries.
In the display, make sure that interfaces Fast Ethernet 0/1 and Fast
Ethernet 0/2 are configured as trunk ports.
When the trunk links come up, Switch 1 receives the VTP information
from the other switches. Verify that Switch 1 has learned the VLAN
configuration.
Enter global configuration mode.
Enter interface configuration mode, and define Fast Ethernet port 0/1 as
the interface to set the STP cost.
Set the spanning-tree path cost to 30 for VLAN 2.
Set the spanning-tree path cost to 30 for VLAN 3.
Set the spanning-tree path cost to 30 for VLAN 4.
Return to global configuration mode.
Repeat Steps 9 through 11 on Switch 1 interface Fast Ethernet 0/2, and
set the spanning-tree path cost to 30 for VLANs 8, 9, and 10.
Return to privileged EXEC mode.
Verify your entries.
In the display, verify that the path costs are set correctly for interfaces
Fast Ethernet 0/1 and 0/2.
(Optional) Save your entries in the configuration file.
