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 port view interface interface-typeinterface-number —Enable a specified Combo port undo shutdownOptionalBy default, of the two ports ina Combo port, the one with asmaller port ID is enabled.In case of a Combo port, only one interface (either the optical port or the electrical port) is active at atime.
