182CHAPTER 9: CONFIGURATION COMMANDS FOR ETHERNET INTERFACES IN BRIDGE MODE

mdi

Syntax	mdi { across auto normal }
	undo mdi
View	Ethernet interface view
Parameter	across: Specifies cross-over cables for the Ethernet interface.
	auto: Configures the Ethernet interface to be auto-sensing for the cable type.
	normal: Specifies straight-through cables for the Ethernet interface.

Description

n

Use the mdi command to configure the cable type that can be sensed by an Ethernet interface.

Use the undo mdi command to restore the system default.

By default, an Ethernet interface senses the type of the network cable connected to it automatically.

The optical port of a Combo port does not support this command.

Example # Configure the interface Ethernet 1/0 to use cross over cable.

Parameter ratio: Maximal ratio of multicast traffic to the total transmission capability of an Ethernet interface, in the range of 1 to 100. Currently, this argument can only be set to 100.

pps max-pps: Specifies the maximal number of multicast packets passing an Ethernet interface per second, in pps, representing packets per second. Currently, the max-ppsargument can only be 190, 380, 760, 1488, 2976, 5952, or 11904.

Description Use the multicast-suppressioncommand to configure multicast storm suppression ratio on an interface.
