I suddenly must configure two cisco switch 2960s within the same network, basically the idea is that through two cables they will physically be connected but logically, in each switch, two ports must look like one and be aggregated.
What should I do? I do not know much about Cisco and Switches.
Any recommendation?
Please Please Please read through Cisco documentation. It's freely accessible and easy to follow: http://www.cisco.com/en/US/products/ps6406/products_installation_and_configuration_guides_list.html
Select the switch with your corresponding IOS version.
But to point you in the right direction you will have to add the ports to a channel-group.
