NOTE:
•
This function is available only for Layer 2 copper ports that support speed auto negotiation, and is
unavailable for combo interfaces.
•
The
speed
and
speed auto
commands supersede each other, and whichever is configured last takes
effect.
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
."
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
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
|
pps
max-pps
|
kbps
max-kbps
}
Optional.
By default, all broadcast traffic is
allowed to pass through.
4.
Set the multicast
suppression threshold ratio.
multicast-suppression
{
ratio
|
pps
max-pps
|
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
|
pps
max-pps
|
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 on an Ethernet interface:
