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

Switch(Config-Port-Range)#
3.2.1.2.6 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
3.2.1.2.7 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
ES4626/ES4650's 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.
Example: Setting the cable type support of Ethernet ports 1/5 -8 to straight-through cable
only.
Switch(Config)#interface ethernet 1/5-8
Switch(Config-Port-Range)#mdi normal
