Lab 01: Two PCs, One Switch

Tool: Cisco Packet Tracer

Objective

Connect two PCs through a switch, assign static IPs, and verify connectivity with ping.

Topology

| Link | Cable |

| PC1 to Switch | Copper straight-through |

| PC2 to Switch | Copper straight-through |

Addressing

| Device | IP Address | Subnet Mask |

| PC1 | 192.168.0.1 | 255.255.255.0 |

| PC2 | 192.168.0.2 | 255.255.255.0 |

| MAC Address |

Configuration

On each PC: Desktop > IP Configuration > Static, then enter the IP and mask. No gateway is needed because both PCs are on the same subnet. The switch runs on its default configuration.

Verification

From PC1:

ping 192.168.0.2

Observations

• PC1 (192.168.0.1) pinged PC2 (192.168.0.2) across the switch: 4 of 4 replies, 0% loss, round-trip times under 1 ms.

• TTL=128 on all replies, the default for Packet Tracer PCs, which fits a single-switch lab with no router.

• ipconfig/all returns "Invalid Command." The correct syntax is ipconfig /all, with a space.

Takeaways

• Devices on the same subnet communicate through a switch without a router.

• Straight-through cable is used for PC to switch.
