Lab 02 - Switch Configuration

Objectives:

• Ensure PCs and switches are connected properly
  • Cable types
    • PC-SW: straight cables
    • SW-SW: gay crossover cables
  • Connections
    • Connect PCs to ports 1-3 and 11-13 of switches
    • Connect switches together with ports 23 and 24
• Configure switches properly
  • Rename switches to SW1-SW4
  • Assign ports 1-10 to VLAN 10
  • Assign ports 11-20 to VLAN 20
  • Set spanning-tree portfast on ports 1-20
  • Set ports 22-24 as trunks for VLAN 10 and 20
  • Set spanning-tree portfast trunk for ports 22-24
  • Set SW2 to be spanning-tree root primary for VLAN 10 and root secondary for VLAN 20
  • Set SW3 to be spanning-tree root secondary for VLAN 20
• Configure static IP addresses for at least 3 computers per switch

Basic Configuration

Run this configuration on each Switch replacing {x} with the switch number:

enable
configure terminal
hostname SW{x}

interface range fastEthernet 0/1-10
switchport mode access
switchport access vlan 10

interface range fastEthernet 0/11-20
switchport mode access
switchport access vlan 20

interface range fastEthernet 0/1-20
spanning-tree portfast

interface range fastEthernet 0/22-24
switchport mode trunk
switchport trunk allowed vlan 10,20
spanning-tree portfast trunk

exit
exit
disable
exit

Configuration of SW2

enable
configure terminal
spanning-tree vlan 10 root primary
spanning-tree vlan 20 root secondary

exit
exit
disable
exit

Configuration of SW3

enable
configure terminal
spanning-tree vlan 10 root secondary
spanning-tree vlan 20 root primary

exit
