Configuration procedure
To set storm suppression thresholds on one or multiple Ethernet interfaces:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter Ethernet interface or
subinterface view.
interface interface-type
{ interface-number |
interface-number.subnumber }
N/A
3. Enable broadcast suppression
and set the broadcast
suppression threshold.
broadcast-suppression { ratio |
pps max-pps }
By default, broadcast traffic is
allowed to pass through an
interface.
4. Enable multicast suppression
and set the multicast
suppression threshold.
multicast-suppression { ratio | pps
max-pps }
By default, multicast traffic is
allowed to pass through an
interface.
5. Enable unknown unicast
suppression and set the
unknown unicast suppression
threshold.
unicast-suppression { ratio | pps
max-pps }
By default, unknown unicast traffic
is allowed to pass through an
interface.
Setting the MDIX mode of an Ethernet interface
NOTE:
Fiber ports do not support the MDIX mode setting.
A physical Ethernet interface comprises 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 the interface to communicate with its peer, set the MDIX mode of the interface mode by using
the following guidelines:
• Generally, set the MDIX mode of the interface to AutoMDIX. Set the MDIX mode of the interface to
MDI or MDIX only when the device cannot determine the cable type.
• When a straight-through cable is used, set the interface to operate in the MDIX mode different than
its peer.
• When a crossover cable is used, set the interface to operate in the same MDIX mode as its peer, or
set either end to operate in AutoMDIX mode.
