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.
