Scenario:

VLANs and EtherChannel need to be implemented in your network. Routing between the VLANs will be supported by the layer 3 switch Main. Once the EtherChannels are created, the root bridge for VLAN 10 will be changed to Main.

Instructions:

Configure IP addressing for all end devices and access layer switches (West and South) according to the Addressing Table above.

VLAN ID	Name	Assigned Ports
10	Students	Fa0/1 - Fa0/10
20	Staff	Fa0/11 - Fa0/20
88	Management

Configure VLANs:

• In all switches, create the VLANs according to the table above.
• In switches West and South, configure ports Fa0/1 - Fa0/20 as access ports and assign them to each VLAN according to the table above. (VLAN 88 has no ports assigned).

Channel Group

Ports

Protocol

1	Main: G0/1, G0/2 West: G0/1, G0/2	PAgP
2	Main: Fa0/21, Fa0/22 South: Fa0/21, Fa0/22	LACP
3	West: Fa0/23, Fa0/24 South: Fa0/23, Fa0/24	PAgP

Configure EtherChannel:

• Create the port channels groups according to the table above.
• Configure each port channel interface as trunk.
• Assign Natvie VLAN 99 to each trunk

Note: on switch Main, you have to configure the trunk encapsulation before you can set the port channel interface as trunk. To configure the trunk encapsulation, type the command:

Main(config-if)#switchport trunk encapsulation dot1q

Configure Inter-VLAN Routing:

• Enable IPv4 routing
• Configure all SVI interfaces on Main

Configure the root bridge for VLAN 10:

• By default, West will be selected as the root bridge. To balance the load, configure Main to be the root bridge for VLAN 10. (Refer to PT 6.2.4)

When the network is fully configured, all devices should be able to ping each other.
