Lab requirements:

1. device management

① Define the host names for different devices based on the topology in the figure.

② Disable domain name resolution globally.

③ Close the line timeout and enable output synchronization under the Console and VTY lines.

④ For secure login, you must create a local user name PingingLab and password CCIE, and call it to the console and vty lines. You must set the privileged password CISCO and require encrypted storage.

⑤ All vswitch management VLANs are vlan1 and the network segment is 192.168.1.0/24. The SW1 management IP address is 192.168.1.1/24, SW2 is 192.168.1.2/24, and SW3 is 192.168.1.3/24, remote management is required.

2. Trunk Technology

① Trunk is forcibly enabled between all vswitches, and 802.1Q is used for encapsulation.

② The Global native vlan is defined as vlan 10.

③ The Trunk must only allow data passing through VLAN1, 10, and 20.

3. VTP Technology

① SW1 is Server, and other switches are Client.

② The VTP management domain is PingingLab and the password is cisco.

③ VTP pruning is enabled globally.

④ Create VLAN10/20 on SW1 and require global synchronization.

⑤ Place different user interfaces in the corresponding VLAN.

4. STP Technology

① To deploy PVST, SW1 is the Root of VLAN10, Secondary of VLAN20, SW2 is the Root of VLAN20, and Secondary of VLAN10 to achieve load balancing.

② Enable Portfast to accelerate user access to network interfaces.

③ Enable Uplinkfast to accelerate convergence of direct connections.

④ Enable Backbonefast to accelerate the convergence of backbone links.

5. L3 Swithing Technology

① SW1 serves as the gateway of VLAN10, and SW2 serves as the gateway of VLAN20. The VLAN10 gateway address is 192.168.10.254/24, and the VLAN20 gateway address is 192.168.255.254/24.

② Deploy the DHCP service on SW1 and SW2 at the same time to facilitate the access of hosts with different VLANs to the network. The primary DNS is 8.8.8.8, and the standby DNS is 114.114.114.114.

③ Enable the layer-3 routing function on the layer-3 Switch and require that the host can communicate with each other between VLANs.

6. Etherchannel Technology

① To achieve link redundancy and provide network bandwidth, L2 Etherchannel technology must be deployed between aggregation layer switches.

7. Port-Security Technology

① To achieve user access security, port security technology must be enabled on all user access interfaces.

② Enable address learning and define the maximum MAC Number as 1.

③ Define that the user violates the rules as shutdown mode and requires automatic recovery after 30 s.
