Configure Etherchannel using LACP mode Active & Passive

Configure Etherchannel using LACP(Link Aggregation Control Protocol) mode Active/Passive

We configure Etherchannel using LACP mode Active and Passive in the following topology.


Above topology, for both switches we use fastEthernet port 0/1, 0/2, 0/3 & 0/4.
So to configure Etherchannel we need to type the following commands in both switches. But in case of mode, in left switch we use "Active" and in right switch we use "Passive".

Configure Etherchannel using PAGP mode Desirable & Auto

Configure Etherchannel using PAGP(Port Aggregation Protocol) mode Desirable/Auto

We configure Etherchannel using PAGP mode Desirable and Auto in the following topology.

Above topology, for both switches we use fastEthernet port 0/1, 0/2, 0/3 & 0/4.
So to configure Etherchannel we need to type the following commands in both switches. But in case of mode, in left switch we use "Desirable" and in right switch we use "Auto".

Configure Etherchannel using PAGP mode ON

Configure Etherchannel using PAGP(Port Aggregation Protocol) mode ON

We configure Etherchannel using PAGP mode ON in the following topology.

Above topology, for both switches we use fastEthernet port 0/1, 0/2, 0/3 & 0/4.
So to configure Etherchannel we need to type the following commands in both switches.

What is Etherchannel or Link Aggregation?

What is Etherchannel or Link Aggregation?

If there is more the one wired connection in between two Switches to get more bandwidth, normally there is only one wired connection is active and the other links are kept blocked by the Switch to avoid looping in between two Switches.

DHCP configuration in Server

Configure DHCP in Server

As I said in the previous post, DHCP can be configured in Server as well as Router; now we're going to configure DHCP in Server.

Its simple. There is no command to configure DHCP in a server. Just give the input in proper field and your DHCP will be configured easily.

For the following topology I configured DHCP.

DHCP configuration in Router

Configure DHCP (Dynamic Host Configuration Protocol) in Router

In DHCP the host is configured dynamically. If a network is configured by DHCP, the PC will get IP, Gateway, Subnet Mask, DNS address dynamically.

DHCP can be configured in Server as well as Router. Here I configured DHCP in Router.
Lets see how can we configure DHCP in Router.

Configure Vlan and VTP in switches on Cisco Packet Tracer

Create Vlan and Configure VTP for switches in Cisco Packet Tracer

Vlan means Virtual Local Area Network. Physically it looks same Network but Logically It's different. And that is why It is called Virtual LAN. Normally the End devices can communicate to the End devices belong to same Vlan but not to different Vlan. If End devices are connected to a switch, belong to two or more different Vlans, you'll need a trunk port to send the data to It's destination. You can do it by configuring VTP. VTP means VLAN Trunking Protocol. You need to add the connection with Cross Over Cable in between two Switches. And make those Interfaces to Trunk Port. After doing this, End Devices of Same Vlan can communicate to each other.

Assign IP in Router Interface

Assign IP in Router Interface on Cisco Packet Tracer

This tutorials is about to create a small network by assigning IP in Router Interface. Beside IP assigning in Router Interface, I change hostname of the router, assign IP in the PCs statically to create the network here.

At first create the following topology in Cisco Packet Tracer. You can add more PCs, even one more switch in this topology.
