switch redundancy

Hello,I am having two layer 2 switches. My requirement is to provide fully redundant LAN. That means PCs are connected with one switch if that fails their connection will not have any down time means they will connect with any other switch to keep on communicating in LAN. Please can any one suggest me an architecture which will suit for CISCO packet tracer.

Good question Leo. 

The best way is to have at least two nic card on your PC (with the same speed). then with etherchannel, you can bring it to two different switch. 

Note that in Etherchannel, you have LACP  and PAGP. LACP is good when you are going on two different switch. two interconnect your switches, you can use stack cable or trunk port between the two switches.

How many NIC cards does your PC have?

 

Have you heard of a term called "EtherChannel"?

I have only one NIC card. I have heard but I need the configuration I am not clear I need the exact configuration.

I have only one NIC card.

Then how is this going to work?  You stated that your PC is connected to one switch.  If this one switch fails and your PC only has one NIC card, then where is redundancy?
