Hey Kristjan, In terms of the speed and duplex, look at the initial configs for lab 1. While you would almost never hard-code the speed and duplex for WLCs, it can be done. Also, keep in mind that you will have console access to the WLCs during the lab. So, even if you changed the switch side first, you would still be able to go in through the console. Of course, that would mean you would have to configure the port settings using the CLI. Jason Boyers - CCIE #26024 (Wireless) Technical Instructor - IPexpert, Inc. Mailto: *[email protected] *
