InterfacesThis chapter describes interface types, both physical and logical, and how to configure them with Dell Networking Operating System (OS).The system supports 10–Gigabit, 25–Gigabit, 40–Gigbit, 50–Gigabit, and 100–Gigabit QSFP 28 interfaces.NOTE: Only Dell-qualified optics are supported on these interfaces. Non-Dell optics for 40–Gigbit, 25–Gigabit, 50–Gigabit, and100–Gigabit are set to error-disabled state.Basic Interface Configuration• Interface Types• View Basic Interface Information• Enabling a Physical Interface• Physical Interfaces• Management Interfaces• VLAN Interfaces• Loopback Interfaces• Null Interfaces• Port Channel InterfacesAdvanced Interface Configuration• Bulk Configuration• Defining Interface Range Macros• Monitoring and Maintaining Interfaces• Link Dampening• Link Bundle Monitoring• Ethernet Pause Frames• Configure the MTU Size on an Interface• Port-pipes• View Advanced Interface InformationTopics:• Interface Types• View Basic Interface Information• Resetting an Interface to its Factory Default State• Enabling a Physical Interface• Physical Interfaces• Egress Interface Selection (EIS)• Management Interfaces• VLAN Interfaces• Loopback Interfaces19372 Interfaces
