To do… Use the command… Remarks
Enter system view system-view —
Enter Ethernet interface view interface interface-type interface-number —
Set speed options for auto negotiation speed auto { 10 | 100 | 1000 } * Optional
NOTE:
•
This function is available only for Layer 2 copper GE ports that support speed auto negotiation.
• The speed and speed auto commands supersede each other, and whichever is configured last takes
effect.
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) as a whole globally in system view or on a per-interface basis in
Ethernet interface view or port group view.
In interface or port group view, you 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.
NOTE:
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 .”
Follow these steps to set storm suppression thresholds on one or multiple Ethernet interfaces:
To do… Use the command… Remarks
Enter system view system-view —
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.
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.
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.
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.
