Lab Project 6 - Configure EtherChannel PAgP

This project is a Cisco Packet Tracer network configuration that demonstrates three important networking technologies: DHCP, Inter-VLAN Routing, and EtherChannel using PAgP. The network consists of a Cisco 2911 router, a multilayer Core Switch, two Cisco 2960 Access Switches, and multiple laptops.

The network is divided into three VLANs:

VLAN 10: 10.10.10.0/24
VLAN 20: 20.20.20.0/24
VLAN 30: 30.30.30.0/24

The Router2911 provides DHCP services for all three VLANs and uses router subinterfaces (G0/1.10, G0/1.20, and G0/1.30) to perform Inter-VLAN Routing using the Router-on-a-Stick method.

To improve the connection between the Core Switch and Access Switches, the project uses EtherChannel with PAgP. Multiple physical FastEthernet links are combined into logical Port-Channels, providing increased bandwidth and link redundancy. PAgP uses desirable mode on the Core Switch to actively negotiate the EtherChannel.

The Access Switches assign end devices to their appropriate VLANs. Laptop0 is connected to VLAN 10, Laptop1 to VLAN 20, and Laptop2 to VLAN 30. The laptops are configured to obtain their IP addresses automatically through DHCP.

Project Objectives
Configure DHCP to automatically assign IP addresses to clients.
Create and configure VLAN 10, VLAN 20, and VLAN 30.
Configure Inter-VLAN Routing using Router-on-a-Stick.
Configure 802.1Q trunking between the router and Core Switch.
Configure EtherChannel using PAgP between the Core Switch and Access Switches.
Verify network connectivity using commands such as show ip dhcp binding, show interfaces trunk, show etherchannel summary, and ping.

In summary, this project demonstrates how VLAN segmentation, automatic IP address assignment, inter-VLAN communication, and link aggregation can work together to create a more organized, reliable, and efficient enterprise network.
