Lab #$1$ Network Configuration:

Objectives:

$1.$ Understand the high level specifications of the Cisco $2960$ Switch

$2.$ Understand how to view the MAC addres table

$3.$ Achieve basic Cisco switch STP$,$ and RSTP provisioning proficiency using IOS commands

$4.$ Measure STP and RSTP fail$-$over and fall$-$back time$($s$)$

$5.$ Learn the relationship between STP$,$ RSTP timers and the actual experiment results

Packet Tracer Information

This lab uses Cisco Packet Tracer. Follow the instructions in Packet Tracer Installation Instructions.pdf to understand how to install Cisco Packet Tracer.

Introduction:

This lab exercise includes three Cisco Catalyst C$2960$G$-24-$EI Ethernet switches $($switch$0,$ switch$1,$ and switch$2).$

After you login to the switch, you are in the user mode. As a user, you can use the show command to view the switch configuration information, but you cannot change the configuration. You need to use the enable command to be in the privilege mode. As a privileged user, you have permission enter various configuration modes. While in the privilege mode, enter the configure terminal command to enter configuration mode.

Login $->$ User Mode $->$ "enable" $->$ Privileged Mode $->$ "configure terminal" $->$ Configuration Mode

The privileged mode password for all switches is cisco.

Test Procedure:

$1.$ To login to each Host:

a$.$ Left click on the Host

b$.$ Select Desktop

c$.$ Select Command Prompt

$2.$ Find the MAC address of $192\mathrm{.}168\mathrm{.}1\mathrm{.}101$ and $192\mathrm{.}168\mathrm{.}1\mathrm{.}102$ of the Host $0$ and Host $1$ by using the following windows command: ipconfig $/$all

Paste a screenshot of this screen showing the ip address and MAC address in your lab report.

$3.$ Configure the Ethernet switches $0-2$ to support the network diagram. In addition to this configuration, perform further provisioning to support the following:

Rename switch $0,$ switch $1,$ and switch $2$ to IllinoisTech, Scarlet, Hawks, respectively

Assign VLAN id $35$ to the switch interfaces that are directly connected to the hosts

Add a description for the switch interfaces that are directly connected to the hosts as Host $0,$ Host $1,$ or Host $2.$

Configure the Switch interfaces that are directly connected to the other switches as VLAN trunks

Add a description for the switch interfaces that are connected to the other switches as Switch $0,$ Switch $1,$ or Switch $2.$

Assign Switch $0$ as the root switch, Switch $2$ as the secondary root switch in the STP

enabled STP on all switches

$2960$ Cisco IOS Command reference: Command reference manual

Some quick tips:

Use the switchport mode access and switchport access vlan $[$id#$]$ Cisco IOS commands to assign VLAN ids to the switch interfaces that are connected to the hosts $($must be in configuration mode$)$

All switch interfaces are by default shutdown. You must enable the switch ports that are to be used in the experiment by issuing the no shutdown Cisco IOS command $($must be in configuration mode$)$

Use the description command to name the interfaces.

Configure Switch $0$ as a STP root switch.

To configure the network to run STP$,$ configure each switch to be in STP mode by entering the following command to each switch:

configure terminal

spanning$-$tree mode pvst

To configure the network to run RSTP$,$ configure each switch to be in RSTP mode by entering the following command to each switch:

configure terminal

spanning$-$tree mode rapid$-$pvst

$4.$ Verify that the VLAN $35$ is properly configured on the Switches $0-2.$ Note that fa$0/1$ should be on VLAN $35.$ You may use the following commands in enable mode:

Device Command

Switch $0$ show vlan id $35$

Switch $1$ show vlan id $35$

Switch $2$ show vlan id $35$

$5.$ In order to determine the physical connections between hosts and switch ports, use the following command on each switch and refer to the lab diagram:

show mac$-$address$-$table

$6.$ Verify that the switches $0-2$ interfaces are in the correct STP state using the command:

show spanning$-$tree vlan $35$

On Switch Scarlet $($switch $1),$ confirm that interface fa$0/23$ is in the BLK state and that interface fa$0/24$ is in the FWD state
