Lab Simulation 41
Guidelines
This is a lab item in which tasks will be performed on virtual devices.
- Refer to the Tasks tab to view the tasks for this lab item.
- Refer to the Topology tab to access the device console(s) and perform the tasks.
- Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.
- All necessary preconfigurations have been applied.
- Do not change the enable password or hostname for any device.
- Save your configurations to NVRAM before moving to the next item.
- Click Next at the bottom of the screen to submit this lab and move to the next question.
- When Next is clicked, the lab doses and cannot be reopened.
Topology

Tasks
Task 1:
Configure trunks between Sw1 and Sw2 on ports E0/0 and E0/1 using the IEEE standard frame tagging method.
- Add the IT_User_VLAN as the untagged VLAN to the trunk.
- Allow only the untagged VLAN and VLANs 20 and 40 on trunks.
- Verify that PC1 pings PC2 and PC3 pings PC4.
Task 2:
On Sw1 and Sw2, use IEEE 802.3ad link aggregation.
- Assign number 10 to the link.
- Combine E0/0 and E0/1 into a single logical link.
- Ensure Sw2 does not negotiate but responds to negotiation requests.
Correct Answer:
See the below explanation
Explanation:
Task 1: Configure Trunks
1. Set up trunking on interfaces E0/0 and E0/1 using IEEE 802.1Q:
interface range e0/0 - 1
switchport mode trunk
switchport trunk encapsulation dot1q
switchport trunk native vlan <IT_User_VLAN_ID>
switchport trunk allowed vlan <IT_User_VLAN_ID>,20,40
2. Verify trunk configuration:
show interfaces trunk
3. Verify connectivity:
ping 10.2.2.20 (From PC1 to PC2)
ping 10.3.3.20 (From PC3 to PC4)
Task 2: Configure Link Aggregation (EtherChannel)
1. On Sw1:
interface range e0/0 - 1
channel-group 10 mode active
exit
interface port-channel 10
switchport mode trunk
switchport trunk encapsulation dot1q
switchport trunk native vlan <IT_User_VLAN_ID>
switchport trunk allowed vlan <IT_User_VLAN_ID>,20,40
2. On Sw2:
interface range e0/0 - 1
channel-group 10 mode passive
exit
interface port-channel 10
switchport mode trunk
switchport trunk encapsulation dot1q
switchport trunk native vlan <IT_User_VLAN_ID>
switchport trunk allowed vlan <IT_User_VLAN_ID>,20,40
3. Verify EtherChannel:

This setup ensures trunking, correct VLAN allowance, and EtherChannel link aggregation with Sw1 in active mode and Sw2 in passive mode, fulfilling the IEEE 802.3ad (LACP) requirement.
