• You understand default gateway

Nothing else.

🔹 14.2 Configure the PC IP (manual)

1. Click PC1
2. Go to Desktop
3. Click IP Configuration
4. Select Static

Enter exactly:

• IP Address: 10.10.10.10
• Subnet Mask: 255.255.255.0
• Default Gateway: 10.10.10.1

🔹 14.3 Test connectivity (first real test)

1. On PC1
2. Desktop → Command Prompt
3. Type:

ping 10.10.10.1

✅ Expected result

You should see:

Reply from 10.10.10.1: bytes=32 time<1ms TTL=255

Even 1 reply is enough.

🧠 What this proves (important)

• Physical cabling is correct
• Switch forwarding works
