A.Enable the switch to participate in routing updates from external devices with the router command in global configuration mode.
B.Enter the no switchport command to disable Layer 2 functionality at the interface level.
C.Each port participating in routing of Layer 3 packets must have an IP routing protocol assigned on aperinterface level.
D.Routing is enabled by default on a multilayer switch， so the port can become a Layer 3 routing interface by assigning the appropriate IP address and subnet information.

B.The port is operational and has reached its configured maximum allowed number of MAC addresses.
C.The port will allow access for 11 MAC addresses in addition to the 3 configured MAC addresses.
D.If the number of devices attempting to access the port exceeds 11， the port will shut down for 20 minutes， as configured.
