Load-Sharing Trunks with Traffic Distributed by Path Cost
Switch A
Trunk port 1
– 4 (path cost 30)
– 10 (path cost 19)
Switch B
Purpose
Enter global configuration mode on Switch A.
Define the interface to be configured as Trunk port 1, and enter interface
configuration mode.
Configure the interface as an NNI or ENI. UNIs do not support STP. If
you configure the port as an ENI, you must also enable STP on the port
by entering the spanning-tree interface configuration command.
Configure the port as a trunk port.
Return to global configuration mode.
Define the interface to be configured as Trunk port 2, and enter interface
configuration mode.
Configure the interface as an NNI or ENI. UNIs do not support STP. If
you configure the port as an ENI, you must also enable STP on the port
by entering the spanning-tree interface configuration command.
Configure the port as a trunk port.
Return to privileged EXEC mode.
Verify your entries. In the display, make sure that the interfaces
configured in Steps 2 and 7 are configured as trunk ports.
Verify that VLANs 2 through 4 and 8 through 10 are configured on
Switch A. If not, create these VLANs.
Enter global configuration mode.
Enter interface configuration mode for Trunk port 2.
Set the spanning-tree path cost to 30 for VLANs 2 through 4.
Return to global configuration mode.
Enter interface configuration mode for Trunk port 2.
Set the spanning-tree path cost to 30 for VLANs 2 through 4.
Return to global configuration mode.
Trunk port 2
VLANs 8 – 10 (path cost 30)
VLANs 2 – 4 (path cost 19)
