mdi { across | auto | normal }
undo mdi
View
Ethernet port view
Parameters
across: Sets the MDI mode to medium dependent interface (MDI).
normal: Sets the MDI mode to media dependent interface-X mode (MDI-X).
auto: Sets the MDI mode to auto-sensing. Port operating in this mode adjust its MDI mode between
MDI and MDI-X automatically.
An RJ-45 interface can operate in MDI or MDI-X mode.
To connect two RJ-45 interfaces operating in the same MDI mode, use a crossover cable; to
connect two RJ-45 interfaces operating in different MDI modes, use a straight-through cable.
The MDI mode of an optical port is fixed to auto.
Description
Use the mdi command to set the MDI mode for a port.
Use the undo mdi command to restore the default setting.
By default, a port operates in auto-sensing MDI mode.
