Note: The VLAN numbers may be different so please check them carefully.


Task 1.

SW1(config)#vlan 100 SW1(config-vlan)#name Compute SW1(config-vlan)#vlan 200

SW1(config-vlan)#name Telephony

SW2 only uses “Compute” VLAN so we only need to configure this VLAN on SW2:

SW2(config)#vlan 100 SW2(config)#name Compute

Task 2.

Check the number of VLAN named “Available” so that we can assign interface E0/1 to this VLAN with the “show vlan” command. Suppose we found VLAN 99 is the “Available” VLAN.

SW2(config)#interface e0/1 SW2(config-if)#switchport mode access

SW2(config-if)#switchport access vlan 99 SW2(config-if)#no shutdown


Task 3.

Configure on both SW1 & SW2:

SW1+SW2(config)#interface e0/0 SW1+SW2(config-if)#switchport mode access SW1+SW2(config-if)#switchport access vlan 100

Task 4.

SW1(config)#interface e0/1 SW1(config-if)#switchport mode access

SW1(config-if)#switchport access vlan 100 SW1(config-if)#switchport voice vlan 200


Task 5.

SW2(config)#interface e0/1 SW2(config-if)#no cdp enable

Don’t forget to save the configuration on both switches: SW1+SW2#copy running-config startup-config

Tasks

Three switches must be configured for Layer 2 connectivity. The company requires only the designated VLANs to be configured on their respective switches and permitted across any links between switches for security purposes. Do not modify or delete VTP configurations.

The network needs two user-defined VLANs configured:

VLAN 110: MARKETING
VLAN 210: FINANCE

1. 
   Configure the VLANs on the designated switches and assign them as access ports to the interfaces connected to the PCs.
   
2. 
   Configure the e0/2 interfaces on Sw1 and Sw2 as 802.1q trunks with only the required VLANs permitted.
   
3. 
   Configure the e0/3 interfaces on Sw2 and Sw3 as 802.1q trunks with only the required VLANs permitted.
   

A. Solution

Task 1.

Sw1(config)#vlan 210

Sw1(config-vlan)#name FINANCE Sw1(config-vlan)#exit Sw1(config)#interface e0/1
Sw1(config-if)#switchport mode access Sw1(config-if)#switchport access vlan 210

Sw2(config)#vlan 110

Sw2(config-vlan)#name MARKETING Sw1(config)#interface e0/1
Sw1(config-if)#switchport mode access Sw1(config-if)#switchport access vlan 110

Sw3(config)#vlan 110

Sw3(config-vlan)#name MARKETING Sw3(config-vlan)#vlan 210 Sw3(config-vlan)#name FINANCE Sw1(config)#interface e0/0
Sw1(config-if)#switchport mode access Sw1(config-if)#switchport access vlan 110 Sw1(config)#interface e0/1
Sw1(config-if)#switchport mode access Sw1(config-if)#switchport access vlan 210

Task 2.

Only the VLAN 210 should be permitted on e0/2 of Sw1 & Sw2 so that PC5 can communicate with PC6. There is no traffic for VLAN 110 on this trunk link so we should not allow VLAN 110 to go through.

Sw1+Sw2(config)#interface e0/2

Sw1+Sw2(config-if)#switchport trunk encapsulation dot1q Sw1+Sw2(config-if)#switchport mode trunk Sw1+Sw2(config-if)#switchport trunk allowed vlan 210

Task 3.

Sw2+Sw3(config)#interface e0/3

Sw2+Sw3(config-if)#switchport trunk encapsulation dot1q Sw2+Sw3(config-if)#switchport mode trunk Sw2+Sw3(config-if)#switchport trunk allowed vlan 110,210

Don’t forget to save the configuration on both switches: SW1+SW2+Sw3#copy running-config startup-config
