Network LAN Design with VoIP and Wireless Services
This section will provide a detailed LAN-design of network with VoIP services, Wireless services, protocols, devices, and interconnectivity, with WAN.
This section includes but not limited to
- Equipment List
- Hierarchical IP scheme and VLAN
- Link IP addresses
- High Level Diagram
- Voice and Wireless Design
Select all networking hardware
|Distribution Switches||Cat 3850 Series Swiches||2||48 port model, wireless capacity/PoE|
|Branch office router||RV220W Wireless||2||4 port switch, built in firewall|
|Access Switches||Cat 2600||10||48 ports|
|Network Monitoring System|
|Cisco Unified Call Manger||2||Voice services|
Now name each device as per naming convention (Since it is new company, make it for them)
|Device||Device Configured Name||Placement||Connection||Comments|
|Cat 3850 Series switch||Data center Switch 1||Data center||Distribution Switch
VLAN1, 2, 8
|The switch has Inventory server, Payroll server, and VLAN 1, 2, 8|
|Core Switch 7600 Series||CoreRouter1||Room#1014||DSW1 and DSW2||ISP1|
Hierarchical IP scheme and VLAN
Create an IP Scheme and VLANS.
I suggest use the table below to create your hierarchical IP addressing scheme.
Power of 2
|Subnet Address Assigned|
Create VLAN: In creating VLAN, I will suggest use organizational structure model for simplicity.
Examples: VPOPRVLAN1, VPOPRVLAN2
High Level Diagram:
Drawing a network topology diagram is the most challenging task. To overcome this challenge, we need to use Cisco modular technology in upgrading the network in other words top down design approach. The top design approach starts with Application, Devices and infrastructure. You will also use the same approach in designing WWTC network. Select all the applications for the network. Then select the devices needed to run these applications. Now you are ready creating network topology diagram. Since, in WWTC network we have one floor, so all of our devices, application and infrastructure will reside in one floor.
Create subnets. Generally, subnet matches organizational structure. Also, in a large network to increase performance or for security reasons, subnets are created. Furthermore, to accommodate the need of a department, the subnets can be subnetted further or VLANs are created or both. Every organization have subnets and VLANs. Let us say we need 20 VLANs, which will serve client’s requirements, performance and security of the network. Assign these VLANs to switches. For example; you need 3 switches to host 3 VLANs for VPOPR. The diagram below depicts the scenario.
