7.2.1.2.4 interface ethernet
Command: interface ethernet
Function: Enters Ethernet Interface Mode from Global Mode.
Parameters: stands for port number.
Command mode: Global Mode
Usage Guide: Run the exit command to exit the Ethernet Interface Mode to Global Mode.
Example: Entering the Ethernet Interface Mode for ports 1/1, 2/4-5, 3/8.
Switch(Config)#interface ethernet 1/1;2/4-5;3/8
Switch(Config-Port-Range)#
7.2.1.2.5 loopback
Command: loopback
no loopback
Function: Enables the loopback test function in an Ethernet port; the “no loopback” command
disables the loopback test on an Ethernet port.
Command mode: Interface 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 1/1 – 8
Switch(Config)#interface ethernet 1/1-8
Switch(Config-Port-Range)#loopback
7.2.1.2.6 mdi
Command: mdi { auto | across | normal }
no mdi
Function: Sets the cable types supported by the Ethernet port; the “no mdi” command sets the
cable type to auto-identification. This command is not supported on ES4710BD line card ports of
1000Mbps or more, these ports have auto-identification set for cable types.
Parameters: auto indicates auto identification of cable types; across indicates crossover cable
support only; normal indicates straight-through cable support only.
Command mode: Interface Mode
Default: Port cable type is set to auto-identification by default.
Usage Guide: Auto-identification is recommended. Generally, straight-through cable is used for
switch-PC connection and crossover cable is used for switch-switch connection.
