I'm hope to setup Cisco with QoS in L2 environment with VoIP traffic. The packets ingress the SW will be marked with DSCP values. The requirement says that if L2 QoS if necessary the L2 Ethernet switches should be used that can implement QoS measures...

I have this error appearing when I boot the 3650 Switch. Is this big issue in production, or can I ignore it?     

  We have a switch with two IOS in the Boot path-list. One does not exists in flash. The one who does exists in flash is the SE10a. Which will the SW boot from? Is there a way to remove the other one?

I suddenly lost connection to a 3650 SW running 03.03.05SE IOS. Does anyone know if there is a common bug on this IOS who does this?
