This Case Study will require you to
- Build a small network using three switches and one router
- One switch will run as a distribution layer switch, the other two will run as access layer switches
- A router will be connected to the distribution layer switch using 802.1Q trunking to route between subnets
- The switches will be connected with two Ethernet links using Ether-channel bonding
- The distribution layer switch will be configured as the STP root bridge
Your Lab Supervisor will provide your group with your:
Allocated network address information
Subnetting requirements for four LANs to operate within your organisation VLAN numbers and VLAN names for each of the four LANs
Network Management VLAN to use in your network
These details will be provided once you have registered your group within ESP and provided those details to your supervisor.
You are required to configure all switches and routers with the following information:
Message of the Day Interface descriptions
Console and Enable passwords ssh Access
All router interfaces are to have the lowest usable IP address of their allocated subnet Further, all switches should be configured such that:
Unallocated ports are disabled
Appropriate switch-port security is configured
In your report you will need to justify your switchport security decisions and configurations.
Vii. Advanced Network Configuration
You will be required to configure 802.1Q trunking connections between the switches. Each switch will be connected to another switch via two trunking connections where the second connection is used for redundancy purposes.
You will be required to configure your network Spanning Tree Protocol to PVST+ and to ensure that the distribution layer switch is the Root Bridge.
Network traffic has grown since you first built your network. The Ethernet trunking channels are no longer capable of carrying the offered load on their own. A decision has been made to change the redundant trunking connections between each switch into a bundled EtherChannel to double the maximumum throughput.
You must reconfigure your network such that the two links connecting the switches now form an EtherChannel. You must ensure that the distribution layer switch remains the Root Bridge for the Spanning Tree Protocol.
In our group the task was to design a network for ‘Many Tongues LTD’ with various hosts’ requirements. This company network was then allocated network address 22.214.171.124/24.
In this task there will be configuration of the network devices which will be a router three switches which will be used to link the computers as the end devices in their respective VLANS.
Various concepts are used in this task which will include the spanning-tree protocol, routers on stick, Ethernet channel bundling, security configuration on the network devices and the various skills used to troubleshoot network.
