Configuring VLAN Trunks

Configuring Trunk Ports for Load Sharing

 

Command or Action

Purpose

Step 4

exit

Returns to global configuration mode.

 

Example:

 

 

Switch(config-if)# exit

 

Step 5

Repeat Steps 2 through 4 on a second interface in Switch

 

 

A or in Switch A stack.

 

Step 6

end

Returns to privileged EXEC mode.

 

Example:

 

 

Switch(config)# end

 

Step 7

show running-config

Verifies your entries. In the display, make sure that the

 

 

interfaces are configured as trunk ports.

 

Example:

 

 

Switch# show running-config

 

Step 8

show vlan

Example:

Switch# show vlan

Step 9

configure terminal

Example:

Switch# configure terminal

When the trunk links come up, Switch A receives the VTP information from the other switches. This command verifies that Switch A has learned the VLAN configuration.

Enters global configuration mode.

Step 10

interface interface-id

Defines the interface on which to set the STP cost, and

 

 

enters interface configuration mode.

 

Example:

 

 

Switch(config)# interface gigabitethernet1/0/1

 

Step 11

spanning-tree vlan vlan-rangecost cost-value

Sets the spanning-tree path cost to 30 for VLANs 2

 

 

through 4.

 

Example:

 

 

Switch(config-if)#spanning-tree vlan 2-4 cost

 

 

30
