Small Enterprise Class Lab

Purpose:

In this lab we use Packet Tracer to design and build a small enterprise network for a community healthcare facility

Materials:

  • Cisco Packet Tracer
  • Packet Tracer Lab Starter File

Objective:

For this lab assignment, I used VLSM to create the following Subnet Table as shown below:

VLAN VLAN_NAME Hosts Needed Network Netmask Router Address DHCP Pool Range
10 Clinic 300 10.20.0.0 /23 10.20.0.1 10.20.0.2 - 10.20.1.50
20 Visitor 300 10.20.2.0 /23 10.20.2.1 10.20.2.2 - 10.20.3.50
30 Office 300 10.20.4.0 /23 10.20.4.1 10.20.4.2 - 10.20.5.50
40 Counseling 150 10.20.6.0 /24 10.20.6.1 10.20.6.2 - 10.20.6.160
1 Default Subnet 150 10.20.7.0 /24 10.20.7.1 10.20.7.1 - 10.20.7.160

The completed network should look similar to below:

Working Notes/Documentation:

Configuring the "Hospital-Router" - Border L3 Switch

===

Setting Switch/Router Hostname

  • (config)# hostname Hospital-Router

Configure VLANs

Here I configured the following VLANs:

VLAN VLAN_NAME
10 Clinic
20 Visitor
30 Office
40 Counseling
1 Default Subnet

I created the new VLANs on the L3 Switch using the commands:

  • (config)# vlan <VLAN-Number>
  • (config-vlan)# name <VLAN-Name>

Enable Routing on L3 Switch

  • # ip routing

Setting up a Default Gateway IP for each VLAN Interface

  • ena > conf t > int vlan <vlan number> > ip address <IP_Address> <Subnet_Mask>
  • ip helper-address <DHCP-Server-IP>
  • no shut <-- Very Important!!

Configuring Trunk Ports

  • ena > conf t > int <int-name> > switchport trunk encapsulation dot1q > switchport mode trunk > no shut

Note: Here, I configured the following interfaces (Fa0/1 --> Data Center, Gi0/1 --> North-Core, Gi0/2 --> South-Core)

Save config to NVRAM

  • Lastly, I ran copy run start on my L3 switch to save the current running config

Data Center Core Config

On the Data Center Core Switch, I used the following config as shown below. Not much trunk port setup was needed here as all network traffic occurred through the Default VLAN 1.

Setting Hostname:

  • ena > conf t > hostname Data-Center-Core

From here, I connected a Crossover Ethernet cable from interface port Gi0/1 to the Hospital Router.

North/South Core Config

===

Configuring Hostname

  • ena > conf t > hostname North/South-Core

Configuring VLANs

I used the following command to configure the necessary VLANs for both Core Switches:

  • ena > conf t > vlan <VLAN-Number> > name <VLAN-Name>

This was used to configure the following VLANs as shown in the table below:

VLAN VLAN_NAME
10 Clinic
20 Visitor
30 Office

Configuring Trunk Ports

During this lab, I decided to set interfaces Gi0/1 (To Router) and Gi0/2 (To Edge) as trunk ports.

I was able to configure the Trunk Ports on my Core Switches using the following command on each interface port:

  • ena > conf t > int <interface-name> > switchport mode trunk > no shut

Save Config

  • copy run start

North/South Edge Switch Config

===

Configuring Hostname

  • ena > conf t > hostname North/South_Wing_Switch

Configuring VLANs

I used the following command to configure the necessary VLANs for both Core Switches:

  • ena > conf t > vlan <VLAN-Number> > name <VLAN-Name>

This was used to configure the following VLANs as shown in the table below:

VLAN VLAN_NAME
10 Clinic
20 Visitor
30 Office

Configuring the Trunk Port

  • ena > conf t > int gi0/1 > switchport mode trunk > no shut

Here I used interface gi0/1 as the trunk port for both the North and South Edge Switches (which would be connected to the respective Core Switches)

Configuring the Access Ports

On each Edge Switch, 6 access ports are needed for the Clinic, 4 ports are needed for Visitors, and 6 access ports are needed for the Office. The following commands below were used to configure the necessary Access Ports for this environment:

  • ena > conf t > int range <range-here> > switchport access vlan <VLAN-Number> > no shut

Note: The Access Ports were assigned as follows - [Fa0/1-6 = Clinic], [Fa0/7-12 = Office], [Fa0/13-16 = Visitor]

Save Config

  • copy run start

Additional South Core Config (Counseling)

In order to configure network access for the Counseling Center, I applied the following configs to the South Core Switch:

===

Created new VLAN

  • ena > conf t > vlan 40 > name Counseling

Configured Trunk Ports

  • ena > conf t > int fa0/1 > switchport mode trunk > no shut

Save Config

  • copy run start

Counseling Switch Config

For the Counseling Switch I used a similar config as the North/South Edge Switches

===

Configure Hostname

  • ena > conf t > hostname Counseling_Center_Switch

Configure VLAN

  • ena > conf t > vlan 40 > name Counseling

Note: Only 1 VLAN is needed for this switch as it only handles network traffic for the Counseling Subnet.

Configure Trunk Port

  • ena > conf t > int gi0/1 > switchport mode trunk > no shut

The Gi0/1 Trunk Port would be connected to the South-Core Trunk Port Fa0/1 via an ST Ethernet cable.

Configure Access Ports

Lastly, I configured ports Fa0/1-10 as access ports for the Counseling Center Switch

  • ena > conf t > int range fa0/1-10 > switchport access vlan 40 > no shut

Save Config

  • copy run start
