Setting The Statistics Polling Interval; Configuring A Layer 2 Ethernet Interface; Configuring Storm Suppression - HP MSR Router Series Configuration Manual

Setting the statistics polling interval

Step
1. Enter system view.
2. Set the statistics polling
interval.
To display the interface statistics collected in the last polling interval, use the display interface command.
To clear interface statistics, use the reset counters interface command.

Configuring a Layer 2 Ethernet interface

Configuring storm suppression

You can use the storm suppression function to limit the size of a particular type of traffic (broadcast,
multicast, or unknown unicast traffic) on an interface. When the broadcast, multicast, or unknown unicast
traffic on the interface exceeds this threshold, the system discards packets until the traffic drops below this
threshold.
Configuration guidelines
When you configure the suppression threshold in pps, the device might convert the configured value into
a multiple of a certain step supported by the chip. As a result, the actual suppression threshold might be
different from the configured one. For the suppression threshold that takes effect, see the prompt on the
device.
Configuration procedure
To set storm suppression thresholds on one or multiple Ethernet interfaces:
Step
1. Enter system view.
2. Enter Ethernet interface or
subinterface view.
3. Enable broadcast suppression
and set the broadcast
suppression threshold.
4. Enable multicast suppression
and set the multicast
suppression threshold.
5. Enable unknown unicast
suppression and set the
unknown unicast suppression
threshold.
