Lab Objective:
The focus of this lab is to understand basic VLAN, VTP, DTP and STP implementation and configuration in Cisco IOS Catalyst switches.
Lab Topology:
The lab network topology is illustrated below:
|
IMPORTANT NOTE If you are using the www.howtonetwork.net racks, please begin each and every lab by shutting down all interfaces on all switches and then manually re-enabling only the interfaces that are illustrated in this topology. |
Task 1
Disable VTP on all switches. All switches should support the configuration, modification and deletion of VLANs.
Task 2
Configure trunking on the switches so that all ports are explicitly trunking and DTP should never be used on any of these ports.
Task 3
Configure VLANs 100 and 200 on all switches and use the default IOS VLAN names. Explicitly configure switch DLS1 with a priority of 8192 so it is elected root for both of these VLANs. Additionally, also explicitly configure switch DLS2 so it is elected backup root for both VLANs.
Task 4
Configure Spanning Tree so that it will remain root bridge in the event that another switch is in advertently misconfigured with a lower priority for VLANs 100 and 200. Test and verify your configuration by specifying a priority of 0 for VLAN 100 on any switch within the STP network.
Task 5
Configure the trunk links on switch DLS2 so that they will be disabled automatically in the event that they do not receive BPDUs. Test and verify your configuration by disabling default BPDU transmission from one of the upstream switches.
Task 6
Ports FastEthernet0/1 through FastEthernet0/5 on switches ALS1 and ALS2 will be connected to hosts in the future. These hosts will reside in VLAN 100. Using only TWO commands, perform the following activities on these ports:
- Assign all of these individual ports to VLAN 100
- Configure the ports as static access port
- Enable PortFast for all the ports
- Disable bundling, i.e. EtherChannel, for these ports
