I've recently added a 3560 switch to my existing gigastack of 3 x 3550 switches. ever since i've added the switch the network has slowed down. any device connected to the new switch is having slow network copy issue. Backups are going on 1MB / minute for all servers connected to the new switch. CNA is having performance issue as well. it takes roughtly 5-7minutes just to open CNA. anyone have any idea of what might be going wrong here? your help is highly appreciated.
