Bonjour,

je suis actuellement une formation dans le but de passer la certifcication Cisco CCNA.

J'ai un examen demain, et je refait les labos via un très chouette programme de Cisco qui simule l'installation d'un réseau. (Packet Tracer 4.1).


j'en suis a un exercice sur la vérification du STP (Spanning Tree Protocol)

voici les instructions :

The following resources are required:
• Two Cisco 2960 switches or other comparable switches
• Two Windows-based PCs, one with a terminal emulation program, one as the host, one as the server
• At least one RJ-45-to-DB-9 connector console cable to configure the switches
• Two straight-through Ethernet cables
• Two crossover Ethernet cables
• Access to the PC command prompt
• Access to PC network TCP/IP configuration

Step 1: Cable the network
a. Connect Host 1 to Switch 1 Fast Ethernet port Fa0/7, using a straight-through Ethernet cable.
b. Connect Host 2 to Switch 2 Fast Ethernet port Fa0/8, using a straight-through Ethernet cable.
c. Connect Switch 1 Fast Ethernet port Fa0/1 to Switch 2 FastEthernet port Fa0/1, using a crossover
Ethernet cable.
d. Create a redundant link between the switches by connecting Switch 1 Fast Ethernet port Fa0/4 to
Switch 2 Fast Ethernet port Fa0/4, using a crossover Ethernet cable.

Step 2: Configure the switches
a. Establish a terminal emulation session to Switch 1 from Host 1.
b. Configure the switch hostname, passwords, interface VLAN 1 IP address, and subnet mask on
Switch 1.
c. Save the configuration.
d. Establish a terminal emulation session to Switch 2 from either Host 1 or Host 2.
e. Configure the switch hostname, passwords, interface VLAN 1 IP address, and subnet mask on
Switch 2.
f. Save the configuration.

Step 3: Configure the hosts
a. Configure each host to use an IP address in the same network as the switches.
b. Configure each host to use the same subnet mask as the switches.

Step 4: Verify connectivity
a. To verify that the network is set up successfully, ping from Host 1 to Host 2.
b. If the ping is not successful, verify the connections and configurations again. Check to ensure that all
cables are correct and that connections are seated.

(le ping fonctionne dans les deux sens)

Step 5: Examine interface VLAN 1 information
a. On SwitchA, enter the command show hardware at the privileged EXEC mode prompt.
What is the MAC address of SwitchA? ___________________________________________
b. On SwitchB, enter the command show hardware at the privileged EXEC mode prompt.
What is the MAC address of SwitchB? ___________________________________________
Which switch should be the root of the spanning tree for this network?
__________________________________________________________________________

C'est là que ça coince :

voici ce que j'ai tapé, mais ça ne marche pas, la commande show hardware ne donne rien et je ne comprend pas pourquoi parce qu'elle devrait marché.

switchA>enable

Alors voilà si vous pouvez m'aider, n'hésitez pas, à mon avis le problème viens du fait que je ne suis pas dans le "privileged EXEC mode prompt"
