1-11 Ethernet Interface ConfigurationGeneral Ethernet Interface ConfigurationGE and 10GE ports on the S5120-EI series Ethernet switches are numbered in the following format:interface type A/B/C.z A: Number of a member device in an IRF stack. If no IRF stack is formed, this value is 1.z B: Slot number on the device. A value of 0 represents the slot where the fixed ports of the deviceare located; a value of 1 represents the slot where the ports of interface expansion card 1 arelocated; a value of 2 represents the slot where the ports of interface expansion card 2 are located.z C: Number of a port on a slot.For more information about interface expansion card, see H3C S5120-EI Series Ethernet SwitchesInstallation Manual.Combo Port ConfigurationIntroduction to Combo portA Combo port can operate as either an optical port or an electrical port. Inside the device there is onlyone forwarding interface. For a Combo port, the electrical port and the corresponding optical port areTX-SFP multiplexed. You can specify a Combo port to operate as an electrical port or an optical port.That is, a Combo port cannot operate as both an electrical port and an optical port simultaneously.When one is enabled, the other is automatically disabled.Configuring Combo port stateFollow these steps to configure the state of a Combo port:To do… Use the command… RemarksEnter system view system-view —Enter Ethernet interface view interface interface-typeinterface-number —Enable a specified Combo port undo shutdownOptionalBy default, of the two ports in aCombo port, the one with asmaller port ID is enabled.
