The objective of this lab is to configure Etherchannel on a network consisting of two switches joined together using two cables. Etherchannel helps bundle multiple links connecting two network devices into one virtual link with a higher bandwidth.
There are three methods of etherchannel configuration, two of which use negotiation protocols for interfaces to form an etherchannel and one of which the interfaces is configured manually. The two methods that uses are negation protocols are Link Aggregation Control Protocol (LACP) and Port Aggregation Protocol (PAgP), while the static method is often referred to as Manual mode (ON mode).
PAgP configuration Lab
PAgP is a link aggregation protocol that works in two modes: auto and desirable.
Auto-mode: interface can respond to PAgP packet negotiation but will never start one on its own.
Desirable mode: interface actively attempts a negotiating state for PAgP packet negotiation.”
The network topology you will work on in this lab is shown below;
Lab Objective
- Configure the PAgP EtherChannel on each of the Cisco switches.
- Verify port channel creation after PAgP Etherchannel creation.
- Run necessary Show commands after PAgP Etherchannel creation.

LACP Configuration Lab
LACP is a standard link aggregation Protocol used to bundle multiple link used to connect two network devices into one link with higher bandwidth. LACP work in two modes; Active and Passive.
Active: The interface actively sends LACP packets in its attempt to form an LACP connection.
Passive: The interface can respond to LACP negotiation but will never initiate on its own.
In this lab, you need to configure LACP on the following network;
Lab Objective
- Configure the LACP Ethernet channel in each of the Cisco switches (create another network).
- Verify Port-channel1 creation on each of the switches.
- Run necessary Show commands after LACP Etherchannel creation.

=========================================Static Etherchannel Configuration Lab
Static Ethernet is a way of bundling multiple physical interfaces into one virtual interface with a higher bandwidth. Unlike PAgP and LACP etherchannels, the network devices involved in static etherchannels do not undergo negotiation to form an etherchannel; instead, the interfaces are configured manually with “mode on” in both switches.
The network Topology for this lab is shown below;
Lab Objective
- Configure a static Ethernet channel in each of the Cisco switches (create another network).
- Verify Port-channel1 creation on each of the switches.
- Run the necessary show commands after static etherchannel creation.
