Step 1. To test the VLANs <strong>and</strong> the trunk, ping from the host in Switch_A port 0/2 to the host in<br />

Switch_B port 0/3.<br />

Was the ping successful? Yes<br />

Why?<br />

Both hosts now belong to the same VLAN.<br />

Step 2. Ping from the host in Switch_B port 0/3 to the switch IP 192.168.1.2.<br />

Was the ping successful? Yes<br />

Why?<br />

Both interfaces are assigned to the same VLAN (VLAN 1).<br />

Step 3. Ping from the host in Switch_B port 0/3 to the switch IP 192.168.1.3.<br />

Was the ping successful? Yes<br />

Why?<br />

Both interfaces are assigned to the same VLAN (VLAN 1).<br />

What conclusions can you draw from the testing that you just performed in regard to VLAN<br />

membership <strong>and</strong> VLANs across a trunk?<br />

Hosts must be grouped together into the same VLAN before they can communicate with each<br />

other. Trunk links carry VLAN traffic across switches.<br />

Step 4. After you complete the previous steps, log off (by typing exit) <strong>and</strong> turn all the devices off.<br />

Then, remove <strong>and</strong> store the cables <strong>and</strong> adapter.<br />
