Assignment: Build and configure a network in packet tracer and observe ICMP traffic through a sniffer.

Problems Encountered:

Hub connecting to sniffer:

This issue completely stumped me. I was unable to get traffic between the hub and the sniffer.

  • I solved this issue by switching the cable type from straight through to cross over.

Helpful Commands:

Setting Up DHCP:

ip dhcp pool <name>

This command creates a pool and gives it a name

network <network-IP> <netmask>

This command shows what IP and netmask the network should use.

default-router <router-IP>

This command sets selected interface as the default.

Configuring Router IP's:

Setting up router interfaces:

  • Turn router off and plug in necessary modules. In this case I needed three FastEthernet modules. Two for two systems directly connected to the router and one for a switch. Make sure to turn the router back on after configuring modules.

Configure router interface for switch:

  • I was able to use the steps above to setup DHCP and assign all systems on this interface with DHCP.

Configure directly connected systems:

  • Assign each interface in the router a different network address. This will be the default gateway address assigned to the system connected to the interface. All system IP's are static and are on the same network as the default gateway.

Enabling DHCP:

  • After configuring DHCP in your router, go to the systems that are connected to the interface. Go to config and settings. Set default gateway to the router interface IP address.
  • Select the interface that is used to connect to the switch, and select DHCP. This should automatically assign a IP address and a subnet mask to your system.
