Lab Simulation 36
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
All physical cabling is in place and verified. Connectivity between all four switches must be established and operational. All ports are pre-configured as 802.1q trunks.
1. Configure both SW-1 and SW-2 ports e0/1 and e0/2 to permit only the allowed VLANs
2. Configure both SW-3 and SW-4 ports e0/2 to permit only the allowed VLANs
3. Configure both SW-1 and SW-2 e0/1 ports to send and receive untagged traffic over VLAN 99
4. Configure both SW-3 and SW-4 ports e0/0 and e0/1 for link aggregation using the industry standard protocol. All ports must immediately negotiate the link aggregation
5. Permit only the allowed VLANs on the new link
