HP MSR2000/3000/4000 Router Series Interface Configuration Guide

Setting the statistics polling interval
Step Command Remarks
1. Enter system view.
system-view N/A
2. Set the statistics polling
interval.
flow-interval interval
By default, the interface statistics
polling interval is 300 seconds.
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 interface discards packets until the traffic drops below
this threshold.
Configuration guidelines
When you configure the suppression threshold in pps or kbps, 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 an Ethernet interface:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter Ethernet interface view.
interface interface-type
interface-number
N/A
3. Enable broadcast suppression
and set the broadcast
suppression threshold.
broadcast-suppression { ratio |
pps max-pps | kbps max-kbps }
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 | kbps max-kbps }
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 | kbps max-kbps }
By default, unknown unicast traffic
is allowed to pass through an
interface.
