Things to Remember

• To change configuration in Cisco, use the commands enable and config t to begin
• Save Cisco Configuration using the command, copy run start, when you want to save the configuration.
• The show run command shows the entire cisco configuration

Console into Catalyst Switch using PuTTy:

• To console into the switch with PuTTy, I connected the Serial Console cable to the console port of the switch and the other end into my workstation
• On my workstation, I looked in Device Manager to see which USB Serial Port was being used for the console cable. I used this information in PuTTY later
• I then used PuTTY to console into the switch using the following settings:
  • Serial Line to Connect: The COM port being used by the console cable
  • Bits per sec : 9600
  • Data bits : 8
  • Parity : none
  • Stop bits : 1
• I then click connect and begin a console session into the switch.

Steps to follow upon boot of Cisco Switch:

• Say no to running startup wizard
• Use the commands:
  • Write erase
  • Reload
• The commands above clear the existing configuration if there is one
• Make sure to say no when asked to save config.

Set Hostname:

• Use the commands hostname HOSTNAME where HOSTNAME is what you want the hostname to be

VLAN Access Port Configuration:

• To configure VLANs on each switch, I used commands similar to the following:
  • interface vlan xxx, where xxx is the VLAN number. This command will bring you the the VLAN configuration terminal for the Central Network
    • I set VLAN 200 for the Central Clinic and VLAN 210 for the Central admin
  • I used the command ip address xxx.xxx.xxx.xxx SUBNET where xxx.xxx.xxx.xxx is the gateway address I used for the VLAN and SUBNET is the subnet mask.
    • For the Central Network, the address for VLAN 200 is 192.168.20.1 with a subnet mask of 255.255.255.0
    • For the Central Network, the address for VLAN 210 is 192.168.21.1 with a subnet mask of 255.255.255.0
  • From the config terminal, I used the command, interface range GigabitEthernet 1/0/x-y where x-y is the interface range, to configure multiple interfaces at one time.
  • From the interface configuration console, I used the command, switchport access vlan x, where x is the VLAN ID, to configure the interfaces to use a VLAN.
    • For ports 2-12, on the North and South switch, we set VLAN 200.
    • For ports 13-24, we set VLAN 210.
• NOTE: To see available ports, use the command “show interfaces”

Trunk Port Configuration:

• On the North and South switches, we set the GigabitEthernet 1/0/1 as the trunk port and on the Central MLS, we set ports GigabitEthernet 2/0/1-3 as the trunk ports.
• For the North and South switches, we set the trunk port using the following commands:
  • interface GigabitEthernet 1/0/1
  • switchport mode trunk
  • switchport trunk encapsulation dot1q
  • switchport trunk allowed vlan 200
  • switchport trunk allowed vlan 210
• On the Central MLS, we used the following commands to configure the trunk ports:
  • Interface range GigabitEthernet 2/0/1-3
  • switchport mode trunk
  • switchport trunk encapsulation dot1q
  • switchport trunk allowed vlan 200
  • switchport trunk allowed vlan 210
• The "switchport trunk encapsulation dot1q” command defines how packets are tagged

Workstations on the Central network can now communicate across VLANs and switches.
