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 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.

multicast-suppression
Syntax multicast-suppression { ratio | pps max-pps }
undo multicast-suppression
View Ethernet interface view, port group view
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-pps argument can only be 190, 380, 760, 1488, 2976, 5952, or 11904.
Description Use the
multicast-suppression command to configure multicast storm
