3Configuring Ethernet interfacesYour device supports the following types of Ethernet interfaces:• Layer 2 Ethernet interfaces—Physical Ethernet interfaces operating at the data link layer(Layer 2) to switch packets.• Layer 3 Ethernet interfaces—Physical Ethernet interfaces operating at the network layer(Layer 3) to route packets. You can assign an IP address to a Layer 3 Ethernet interface.• Layer-configurable Ethernet interfaces—Physical Ethernet interfaces that can be configuredto operate in bridge mode as Layer 2 Ethernet interfaces or in route mode as Layer 3 Ethernetinterfaces.Configuring common Ethernet interface settingsThis section describes the settings common to Layer 2 Ethernet interfaces and Layer 3 Ethernetinterfaces. For more information about the settings specific to Layer 2 Ethernet interfaces, see"Configuring a Layer 2 Ethernet interface." For more information about the settings specific to Layer3 Ethernet interfaces, see "Configuring a Layer 3 Ethernet interface."Ethernet interface naming conventionsThe Ethernet interfaces are named in the format of interface-type A/B/C, where the followingdefinitions apply:• A—Represents the member ID of an IRF member switch. If the switch is not in an IRF fabric, Ais 1 by default.• B—Represents the slot number of the card. 0 indicates the interface is a fixed interface of theswitch. 1 indicates the interface is on expansion interface card 1. 2 indicates the interface is onexpansion interface card 2.• C—Represents the number of an interface.A 10-GE breakout interface split from a 40-GE interface is named in the format of interface typeA/B/C:D. A/B/C is the interface number of the 40-GE interface and D is the number of the 10-GEinterface, which is in the range of 1 to 4.Splitting a 40-GE interface and combining 10-GE breakoutinterfacesSplitting a 40-GE interface into four 10-GE breakout interfacesIMPORTANT:• For an S7502E-XS switch, all 40-GE interfaces support this feature.• For an S7504E-XS switch, only the 40-GE interfaces numbered 1 through 6 on theLSQM1QGS8A0 interface module support this feature.You can use a 40-GE interface as a single interface. To improve port density, reduce costs, andimprove network flexibility, you can also split a 40-GE interface into four 10-GE breakout interfaces.For example, you can split a 40-GE interface FortyGigE 1/1/16 into four 10-GE breakout interfacesTen-GigabitEthernet 1/1/16:1 through Ten-GigabitEthernet 1/1/16:4.After you configure this feature on a 40-GE interface, you do not need to reboot the device. Thesystem deletes the 40-GE interface and creates the four 10-GE breakout interfaces.
