Section 51 Tasks

  • Complete the challenge labs below
  • Review the subject of your choice
  • Read the ICND2 cram guide (and the ICND1 cram guide, if taking the CCNA exam)
  • Spend 15 minutes on the subnetting.org website

Section 51 Lab 1 – STP and VLANs

Topology

Section 51 – Review 9 1

Instructions

Connect to the switch using a console connection. Connect a PC to each switch, or connect the switch to the FastEthernet port on a router:

  1. Add IP addresses to the PCs or router Ethernet interfaces
  2. Create VLAN20 on the switch
  3. Set the ports the PCs connect to as access ports (default, but do it anyway)
  4. Put the two switch ports into VLAN20
  5. Check which switch is the Root Bridge
  6. Force the other switch to become the Root Bridge
  7. Hard set the switch ports to the PCs to 100Mbps and full duplex
  8. Wait 30 seconds and test a ping

Solution Hints and Commands

  • Use the vlan 20 command to create VLAN
  • sw mode access
  • sw access vlan 20
  • show spanning-tree [parameters]
  • span vlan 20 root primary
  • speed 100 / duplex full

Section 51 Lab 2 – VLANs

Topology

Section 51 – Review 9 2

Instructions

Connect to the switch using a console connection. Connect two PCs to each switch, or connect the switch to the FastEthernet port on two routers:

  1. Add IP addresses to the PCs or router Ethernet interfaces
  2. Create VLAN20 and VLAN21 on the switch
  3. Set the ports the PCs connect to as access ports (default, but do it anyway)
  4. Put two switch ports into VLAN20 and two switch ports into VLAN21; you can choose which subnets go into which VLANs
  5. Check which switch is the Root Bridge
  6. Force the other switch to become the Root Bridge for VLAN21 only
  7. Ping from 172.16.1.1 to 172.16.1.2, and then from 192.168.1.1 to 192.168.1.2; you won’t be able to ping between subnets, as there is no router involved

Solution Hints and Commands

  • Same as in the previous lab.
