The Cisco Nexus 3000 Series switch does not fragment frames. As a result, the switch cannot have two ports in the same Layer 2 domain with different maximum transmission units (MTUs). A per-physical Ethernet interface MTU is not supported. Instead, the MTU is set according to the QoS classes.hen you enter the interface command, you specify the following information: 1  Interface typeâAll physical Ethernet interfaces use the ethernet keyword. 2  Slot number. 3  Slot 1 includes all the fixed ports. 4  Slot 2 includes the ports on the upper expansion module (if populated).
