Once you create the LAG, clicking apply will not reboot the switch. If users are active on the ports you are trying to link together, there may be an interruption. 
Hi, I need to setup link aggregation on two PowerConnect 2748 switches, I understand how to do this but when I click on the Apply button will the switch reboot? In other words is it safe (as long as I am careful!) to set this up while users are active on my network? Thanks in advance, Richard.
