1.1.5 interface ethernet

 Command: interface ethernet <interface-list>

 Function: Enters Ethernet Port Mode from Global Mode.

 Parameters: <interface-list> stands for port number.

 Command mode: Global Mode

 Usage Guide: Run the exit command to exit the Ethernet Port Mode to Global Mode.

 Example: Entering the Ethernet Port Mode for ports1/0/1，1/0/4-5，1/0/8。

 Switch(config)#interface ethernet 1/0/1;1/0/4-5;1/0/8

 Switch(Config-If-Port-Range)#

1.1.6 loopback

 Command: loopback

 no loopback

 Function: Enables the loopback test function in an Ethernet port; the no command

disables the loopback test on an Ethernet port.

 Command mode: Port Mode.

 Default: Loopback test is disabled in Ethernet port by default.

 Usage Guide: Loopback test can be used to verify the Ethernet ports are working

normally. After loopback has been enabled, the port will assume a connection

established to itself, and all traffic sent from the port will be received at the very same

port.

 Example: Enabling loopback test in Ethernet ports 1/0/1-8.

 Switch(config)#interface ethernet 1/0/1-8

 Switch(Config-If-Port-Range)#loopback

1.1.7 media-type

 Command: media-type {copper | fiber}

 Function: Sets to combo port mode (combo ports only).

 Parameters: copper forces use of copper cable port; fiber forces use of fiber cable

port.

 Command mode: Port Mode.

 Default: The default setting for combo mode of combo ports is the forced fiber port.

 Usage Guide: The combo mode of combo ports and the port connection condition

determines the active port of the combo ports. A combo port consists of one fiber port

and a copper cable port. It should be noted that the speed-duplex command applies to

the copper cable port while the negotiation command applies to the fiber cable port,

they should not conflict. For combo ports, only one, a fiber cable port or a copper cable

port, can be active at a time, and only this port can send and receive data normally.

 Note:

 Combo port is a conception involving the physical layer and the LLC sublayer of the

datalink layer. The status of a combo port will not affect any operation in the MAC
