Setting The Mdix Mode Of An Ethernet Interface - H3C S7500E-XS Series Interface Configuration Manual

Configuration restrictions and guidelines
For the same type of traffic, do not configure storm control together with storm suppression.
Otherwise, the traffic suppression result is not determined. For more information about storm
suppression, see
Configuration procedure
To configure storm control on an Ethernet interface:
Step
1. Enter system view.
2. (Optional.) Set the statistics
polling interval of the storm
control module.
3. Enter Ethernet interface
view.
4. (Optional.) Enable storm
control, and set the lower
and upper thresholds for
broadcast, multicast, or
unknown unicast traffic.
5. Set the control action to take
when monitored traffic
exceeds the upper
threshold.
6. (Optional.) Enable the
Ethernet interface to output
log messages when it
detects storm control
threshold events.
7. (Optional.) Enable the
Ethernet interface to send
storm control threshold
event traps.

Setting the MDIX mode of an Ethernet interface

IMPORTANT:
Fiber ports do not support the MDIX mode setting.
A physical Ethernet interface has eight pins, each of which plays a dedicated role. For example, pins
1 and 2 transmit signals, and pins 3 and 6 receive signals. You can use both crossover and
straight-through Ethernet cables to connect copper Ethernet interfaces. To accommodate these
types of cables, a copper Ethernet interface can operate in one of the following Medium Dependent
Interface-Crossover (MDIX) modes:
•
MDIX mode—Pins 1 and 2 are receive pins and pins 3 and 6 are transmit pins.
•
MDI mode—Pins 1 and 2 are transmit pins and pins 3 and 6 are receive pins.
•
AutoMDIX mode—The interface negotiates pin roles with its peer.
To enable a copper Ethernet interface to communicate with its peer, set the MDIX mode of the
interface by following these guidelines:

Remarks
N/A
The default setting is 10 seconds.
For network stability, use the
default or set a longer statistics
polling interval.
N/A
By default, storm control is
disabled.
By default, storm control is
disabled.
By default, the Ethernet interface
outputs log messages when
monitored traffic exceeds the
upper threshold or drops below
the lower threshold.
By default, the Ethernet interface
sends traps when monitored
traffic exceeds the upper
threshold or drops below the
lower threshold from the upper
threshold.
