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, 1/4-5, 1/8.
Switch(Config)#interface ethernet 1/1;1/4-5;1/8
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
ES4624-SFP/26-SFP’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
