Interfaces | 121Disabling and Re-enabling a Physical InterfaceBy default, all port interfaces on an Aggregator are operationally enabled (no shutdown) to send andreceive Layer 2 traffic. You can reconfigure a physical interface to shut it down by entering the shutdowncommand. To re-enable the interface, enter the no shutdown command.To confirm that the interface is enabled, use the show config command in INTERFACE mode.To leave INTERFACE mode, use the exit command or end command.You cannot delete a physical interface.The management IP address on the D-fabric provides a dedicated management access to the system.The switch interfaces support Layer 2 and Layer 3 traffic over the 100/1000/10000, 10-Gigabit, and40-Gigabit Ethernet interfaces. These interfaces can also become part of virtual interfaces such as virtuallocal area networks (VLANs) or port channels.For more information about VLANs, refer to VLANs and Port Tagging. For more information about portchannels, refer to Port Channel Interfaces.Step Command Syntax Command Mode Purpose1 interface interface CONFIGURATION Enter the keyword interface followed by the type of interface andslot/port information:• For a 10GbE interface, enter the keyword TenGigabitEthernetfollowed by the slot/port numbers; for example, interfacetengigabitethernet 0/56.• For the management interface on a stack-unit, enter thekeyword ManagementEthernet followed by the slot/portnumbers; for example, interface managementethernet 0/33.2 shutdown INTERFACE Enter the shutdown command to disable the interface.FTOS Behavior: The Aggregator uses a single MAC address for all physical interfaces.
