1Configuring Ethernet interfacesEthernet interface naming conventionsThe Ethernet interfaces on the S3600V2 switches are named in the format of interface-type A/B/C,where the following definitions apply:• A—Represents the ID of the switch in an IRF fabric. If the switch is not assigned to any IRF fabric, Auses 1.• B—Represents a slot number on the switch. It takes 0.• C—Represents the number of an interface on a slot.Performing general configurationsThis section describes the attributes and configurations common to Layer 2 and Layer 3 Ethernetinterfaces.• For more information about the attributes and configuration of Layer 2 Ethernet interfaces, see"Configuring a Layer 2 Ethernet interface."• For more information about the attributes and configuration of Layer 3 Ethernet interfaces, see"Setting the MTU for a Layer 3 Ethernet interface."Configuring a combo interfaceA combo interface is a logical interface that comprises one optical (fiber) port and one electrical (copper)port. The two ports share one forwarding interface, so they cannot work simultaneously. When youenable either port, the other port is automatically disabled.The fiber combo port and the copper combo port share one interface view, in which you can activate thefiber or copper combo port and configure other port attributes such as the interface rate and duplexmode.Configuration prerequisitesBefore you configure combo interfaces, complete the following tasks:• An S3600V2 switch provides two combo interfaces. The fiber port and copper port of a combointerface have the same port number. For more information about the combo interface numbers, seethe installation guide of a specific model.• Use the display interface command to determine which port (fiber or copper) of the combointerface is active. If the current port is the copper port, the output will include "Media type istwisted pair, Port hardware type is 1000_BASE_T". If the current port is the fiber port, the output willnot include the information mentioned above. You can also use the display this command in theview of the combo interface to view the combo interface configuration. If the combo enable fibercommand exists, the fiber port is active; if the command does not exist, the copper fiber is active.Changing the active port of a combo interface
