Configuring storm suppression
In interface or port group view, you can set the maximum size of broadcast, multicast, or unknown
unicast traffic allowed to pass through an interface or each interface in a port group. 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.
The storm suppression thresholds configured for an Ethernet interface might become invalid if you
enable the storm control function for the interface. For information about the storm control function,
see "Configuring storm control on an Ethernet interface."
T
o 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
view or port group view.
• Enter Ethernet interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
Use either command.
To configure storm suppression
on an Ethernet interface, enter
Ethernet interface view.
To configure storm suppression
on a group of Ethernet
interfaces, enter port group
view.
3. Set the broadcast
suppression threshold
ratio.
broadcast-suppression
{ ratio |
kbps
max-kbps }
Optional.
By default, all broadcast traffic
is allowed to pass through.
4. Set the multicast
suppression threshold
ratio.
multicast-suppression
{ ratio |
kbps
max-kbps }
Optional.
By default, all multicast traffic is
allowed to pass through.
5. Set the unknown unicast
suppression threshold
ratio.
unicast-suppression
{ ratio |
kbps
max-kbps }
Optional.
By default, all unknown unicast
traffic is allowed to pass
through.
NOTE:
For an Ethernet interface that belongs to a port group, if you set a traffic suppression threshold for
the interface in both Ethernet interface view and port group view, the threshold configured last takes
effect.
Setting the statistics polling interval
To set the statistics polling interval globally or 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. Set the statistics polling
interval on the Ethernet
interface.
flow-interval
interval
Optional.
The default interface statistics
polling interval is 300 seconds.
