Remove the switch startup configuration file from NVRAM.

Switch#erase startup$-$config

The responding line prompt will be:

Erasing the nyram filesystem will remove all files! Continue? $[$confirm$]$

Press Enter to confirm

Step $1$ Configure the switches

Configure the hostname, access and command mode passwords, as well as the management

LAN settings. These values are shown in the chart. If problems occur while performing this

configuration, refer to the Basic Switch Configuration lab.

Step $2$ Configure the hosts attached to the switches

Configure the host to use the same subnet for the address, mask, and default gateway as on

the switch

Step $3$ Verify connectivity

a$.$ To verify that the hosts and switches are correctly configured, ping the switches from the

hosts. b$.$ Were the pings successful?

c$.$ If the answer is no$,$ troubleshoot the hosts and switches configurations.

Step $4$ Display the show interface VLAN options

a$.$ Type show interface vlan $1.$

b$.$ List some of the options available:

Step $5$ Display VLAN interface information

a$.$ On Switch $A,$ type the command show interface VLAN $1$ at the Privileged EXEC mode

prompt as follows:

Switch A#show interface vlan $1$

b$.$ What is the MAC address of the switch?

$\frac{?}{\text{b}\text{a}\text{r}}(c.On$ Switch $B$ type the command show interface VLAN $)1$ at the Privileged EXEC mode

prompt as follows:

Switch.BHshow interface vlan $1$

d$.$ What is the MAC address of the switch?

e$.$ Which switch should be the root of the spanning$-$tree for VLAN $1?$

Step $6$ Display the spanning$-$tree table on each switch

a$.$ At the Privileged EXEC mode prompt, type the following on SWitch A:

Type show spanning$-$tree brief if running version $12\mathrm{.}0$ of the IOS. If running version $12\mathrm{.}1$

of the IOS, type show spanning$-$tree.

Switch $A$# show spanning$-$tree brief

b$.$ On Switch $B$ type show spanning$-$tree brief at the Privileged EXEC mode prompt as

follows:

Switch $B$ B#show spanning$-$tree brief

Examine the output and answer the following questions.

c$.$ Which switch is the root switch? d$.$ What is the priority of the root switch?

e$.$ What is the bridge id of the root switch?

f$.$ Which ports are forwarding on the root switch?

g$.$ Which ports are blocking on the root switch?

h$.$ What is the priority of the non$-$root switch?

i$.$ What is the bridge id of the non$-$root switch?

j$.$ Which ports are forwarding on the non$-$root switch?

k$.$ Which ports are blocking on the non$-$root switch?

I. What is the status of the link light on the blocking port?d$.$ What is the priority of the root switch?

e$.$ What is the bridge id of the root switch?

f$.$ Which ports are forwarding on the root switch?

g$.$ Which ports are blocking on the root switch?

h$.$ What is the priority of the non$-$root switch?

i$.$ What is the bridge id of the non$-$root switch?

j$.$ Which ports are forwarding on the non$-$root switch?

k$.$ Which ports are blocking on the non$-$root switch?

I. What is the status of the link light on the blocking port?SECTION B: Procedures:

Selecting the Root Bridge

Erasing and Reloading the Switch

It is necessary to start with an unconfigured switch. Use of a switch with an existing

configuration may produce unpredictable results. These instructions allow preparation of the

switch prior to performing the lab so previous configuration options do not interfere. The

following is the procedure for clearing out previous configurations and starting with an

unconfigured switch.

$2900$ and $2950$ Series Switches

Enter into the privileged EXEC mode by typing enable.

If prompted for a password, enter class $($if that does not work, ask the instructor$).$

Switch $>$ enable

Remove the VLAN database information file.

Switch#delete flash:vlan.dat

Delete filename $[$vlan$.$dat$]?[$Enter$]$ Delete flash:vlan.dat? $[$confirm$][$Enter$]$

If there was no VLAN file, this message is displayed.
