Lab instructions

This lab will test your ability to configure speed, duplex, and vlan settings on a cisco switch interfaces.

1. Connect to Switch0 using console interface and configure each Switch0 fastethernet switchport for operation. Correct settings are :
- Port type : access port
- Speed : 100 Mbit/s
- Duplex mode : Full Duplex
- Autonegotiation disabled

 

2. PC "192.168.1.4" seems to be unable to ping other PCs in the network. Check switch configuration.
TIP : How many broadcast domains are there in this network ?

 

3. Choose the right cable to connect :
- Switch0 gigabitethernet 1/1 to Switch1 gigabitethernet 1/1
- Switch1 gigabitethernet 1/2 to Switch2 gigabitethernet 1/2

 

4. Configure those two links as trunk lines without using trunk negotiation between switches

Solution

Connect to Switch0 using console interface and configure each Switch0 fastethernet switchport for operation.

Switch(config)#interface FastEthernet0/1

switchport mode access
duplex full
speed 100

Switch(config)#interface FastEthernet0/2

switchport mode access
duplex full
speed 100

Switch(config)#interface FastEthernet0/3

switchport mode access
duplex full
speed 100

Switch(config)#interface FastEthernet0/4

switchport mode access
duplex full
speed 100

 

PC "192.168.1.4" seems to be unable to ping other PCs in the network. Check switch configuration.
Switch(config)#interface FastEthernet0/4

Switch(config-if)#switchport mode access

Switch(config-if)#switchport access vlan 1

 


Choose the right cable to connect :
- Switch0 gigabitethernet 1/1 to Switch1 gigabitethernet 1/1
- Switch1 gigabitethernet 1/2 to Switch2 gigabitethernet 1/2

Configure those two links as trunk lines without using trunk negotiation between switches

On every interface that has to be configured for trunk operation, configure the following settings

Switch(config)#interface GigabitEthernet1/X

Switch(config-if)#switchport mode trunk

 

Verify interface operational mode using the "show interface GigabitEthernet1/X switchport command" :

Name: Gig1/2

Switchport: Enabled

Administrative Mode: trunk

Operational Mode: trunk

Administrative Trunking Encapsulation: dot1q

Operational Trunking Encapsulation: dot1q

Negotiation of Trunking: On

Access Mode VLAN: 1 (default)

Trunking Native Mode VLAN: 1 (default)

Voice VLAN: none

 

 

Another usefull ios command is "show interfaces trunk" :

Switch#sh interfaces trunk
Port        Mode         Encapsulation  Status        Native vlan
Gig1/2      on           802.1q         trunking      1

Port        Vlans allowed on trunk
Gig1/2      1-1005

Port        Vlans allowed and active in management domain
Gig1/2      1

Port        Vlans in spanning tree forwarding state and not pruned
Gig1/2      1
